Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 16-3Corrective Maintenance using Status Display PagesStatus Display PagesStatus display pages are the principle interface between the technician/operator and the Series II cellular system. They allow the technician to view system status, generate status reports, enter commands, and receive system responses.Status display pages are graphical displays that represent the hardware and software subsystems of the cell site and also display a nearly real-time status of all the cell sites serving the Executive Cellular Processor (ECP). Fault conditions received by the ECP for any of the cell sites on the network are indicated at the top of the status display page via colors and flashing indicators. The technician may then bring up a visual display of the particular cell site that issued the fault condition. Status display pages allow the ECP technician to: check the status of cell site hardware units, generate output reports on cell site hardware units, remove (deactivate), restore (activate), and switch cell site hardware units; and inhibit, allow, and run diagnostics on cell site hardware units. The commands entered using the status display page are entered at the command line at the bottom of the status display page.This section addresses status display pages. In particular, it:■Identifies and describes the major status display pages■Gives directions for displaying them on the screen■Identifies and describes the major indicators on the status display pages2130 - Cell Site Status Summary Display PageThe 2130 - Cell Site Status Summary page (See Figure 16-1) provides overall summary status for each Cell Site.2130 - Procedure to Analyze the 2130 - Cell Site Status Summary Page■Select ECP Control & Display from the AUTOPLEX(R) System 1000 ECP Access menu. ■Open the 2130 - Cell Site Status Summary page.■Analyze the overall status of each Cell Site or a specific Cell Site (See Figure 16-1, and Table 16-1).■For more information about a specific Cell Site, use the page commands to navigate to the desired cell status display page. For details about other cell status display pages, refer to the appropriate section in this document.

There are two screens: one to show the status of locate and beacon radios, and another to show the status of setup and beacon radios.The locate radios screen version has commands to:■Conditionally remove and restore LC radios■Diagnose LC radios■Generate LC radios status message output reports.The setup radios screen version has commands to:■Conditionally remove and restore SU radios■Diagnose SU radios■Generate SU radios status message output reports.In addition, all screen versions allow you to generate Cell Site status message output reports.AMPS setup and analog locate radios are simply RCUs or SBRCUs configured to perform setup and analog locate channel functions. Normally, at startup, two setup radios (one active and one standby) and two locate radios (both active) are used.Setup radios perform the receive and transmit functions required to set up an AMPS or TDMA call,* but not a CDMA call. CDMA uses its own control channels to set up a CDMA call.Analog locate radios, which receive but do not transmit, assist only in the handoff of an AMPS call. As explanation, a handoff decision for an AMPS call is based on Cell Site measurements of signal strengths received from the mobile station. In contrast, the handoff decision for a TDMA or CDMA call is based on mobile * Unless the Cell Site has the TDMA digital control channel (DCCH) feature, in which case the DCCH is used to set up calls for IS-136 compliant TDMA/AMPS dual-mode mobiles.
Lucent Technologies — ProprietarySee notice on first page16-28 401-660-100 Issue 11 August 2000Corrective Maintenance using Status Display Pagesmeasurements of signal strengths received from radios at neighboring sites. This latter type of handoff is referred to as mobile-assisted handoff (MAHO).A feature known as the digital verification color code (DVCC) verification feature can ensure a high success rate for the TDMA MAHO procedure. For this feature, there is a digital locate radio (L-DRU) available to each physical antenna face, or sector, neighboring the serving face. (An L-DRU can carry one, two, or three digital locate channels.) Both analog and digital locate radios (L-RCUs,L-SBRCUs, L-DRUs) for the cell are displayed on the 2135 page.Beacon radios (B-DRUs, B-EDRUs), which may also be realized by analog voice radios (V-RCUs, V-SBRCUs), are instrumental in the TDMA MAHO procedure. A beacon radio has its transmitter On all the time and transmits at a fixed power level. Beacon radios may also carry voice (traffic) channels.For the TDMA MAHO feature, there is one beacon or beacon-like* radio associated with each physical antenna face, or sector, neighboring the serving face. The Cell Site sends a list of MAHO channels associated with the neighboring faces to the TDMA/AMPS dual-mode mobile assigned to a TDMA digital traffic channel. The dual-mode mobile periodically measures the strength of the MAHO channels (as well as the strength and bit error rate of the serving TDMA digital traffic channel) and reports the results to the serving cell. It is from these measurements that the serving cell decides whether a neighboring face can better serve the call.* AMPS setup radios and TDMA digital control channel (DCCH) radios qualify as beacon-like radios because they have their transmitters On all the time and transmit at fixed power levels. The RF operating frequencies of the beacon and beacon-like radios together constitute the MAHO channels.

The fiber-link microcell system can handle any combination of AMPS, TDMA, and CDMA radio equipment simultaneously.The LMT consists of a low-power RF radiator device inside a weather-hardened housing. It is intended for remote indoor or outdoor deployment, and may be located up to 7 miles (11.2 km) from the Series II Cell Site.The optical interface equipment at the host Cell Site provides the electrical-to-optical interface between the host Cell Site and the fiber-link microcell system. There is a single-shelf modular optical interface shelf (OIS) that supports up to four LMTs, or the larger OIF that supports up to 21 LMTs. For each LMT, there must be one installed OTU in the OIS or OIF.One or more LMTs can function as a sector of a host cell; as many as eight LMTs may be assigned to a sector. LMTs may be assigned to all sectors of an AMPS Series II Cell Site as long as the total number of LMTs does not exceed 21: an AMPS Series II Cell Site is limited to a maximum of 21 LMTs.

It can be configured as an overhead channel (pilot/sync/access or page) or a traffic (voice) channel.■BCR-BIU-ACU (BBA)A baseband combiner and radio (BCR) and its associated bus interface unit (BIU) and analog conversion unit (ACU) form a CDMA radio set—the BBA (for BCR-BIU-ACU). Because the BBA is a single point failure for a sector, redundant BBAs—one active and the other in standby mode—may be installed for increased reliability. (A BBA pair is redundant.) For OA&M purposes, the BBA is treated as a single maintenance unit.The 2138 page shows the following information for each CCC:■Number of channel elements (CEs) out-of-service■Associated packet pipe (PP) trunk group member.The 2138 page shows the following information for each BBA pair:■Assigned CDMA channel (carrier) number■Associated physical antenna face (PAF).In addition, the 2138 page shows the identity of the serving DCS, packet pipe trunk group, and the Global Positioning System (GPS) alarms status.

The transmit bus can bypass a slot in which a CCU is either not present or has been removed from service, but it cannot bypass two (or more) adjacent slots.Be aware that the removal of any two adjacent CCUs will break the transmit bus path, thereby disrupting the transmit data upstream from the break. As an example, removing CCUs 2 and 3 will also remove CCUs 4 through 7. For a conditional remove request, MRA will not permit the removal of two adjacent CCUs if the removal would result in exceeding the traffic CE out-of-service threshold limit. For an unconditional remove request, MRA will allow the removal of two adjacent CCUs with no regard for the traffic CE out-of-service threshold limit.2139 Procedure to Remove/Restore/Diagnose or Generate a Status Report for CCUs 01.

Maintenance commands are also available on this display page.IS-54 TDMA is enhanced by implementing the DCCH feature as described in the IS-136 standard. The DCCH performs the setup function for mobile subscribers using IS-136 compliant TDMA/AMPS dual-mode mobiles.The DCCH is used in place of the analog control channel (ACC). The DCCH is carried by a TDMA radio (DRU, EDRU) configured as a DCCH radio, and the ACC is carried by an AMPS radio (RCU, SBRCU) configured as a setup radio. For the TDMA radio (DRU, EDRU), there is one non-volatile memory (NVM) image file for the DCCH radio, digital voice radio, and digital beacon radio. The RCC downloads the personality type and other specific parameter values to each TDMA radio at initialization. Since a TDMA radio provides a basic modulation efficiency of three user channels (1 - 3) per 30-kHz of bandwidth, the DCCH radio may also carry digital traffic and beacon channels. The DCCH is carried on user channel 1.Typically, there is one DCCH per physical antenna face, or sector, in a TDMA system. Up to three DCCHs are allowed per sector.

Previously, the OOS could only be defined, or set, on a per-cell level. Because the software that performed the OOS checking for conditional OA&M commands, checked on a per LAF basis, it was possible for the per-cell OSS limits to block the testing of radios on a specific LAF. This is no longer a problem. The ability to set OOS limits on a per LAF basis allows the service-provider to set the voice radio OSS limits at the same level at which the Cell Site software performs the OOS checking for conditional OA&M commands; that is, at the per LAF level. New RC/V Translation Parameters 0This feature adds 4 new AMPS and TDMA Voice Radio OOS limit translations to the ceqface form, as below:1. AMPS Voice Radio OOS Limit Server Group 0.

When CDMA is introduced into a service area, the CDMA frequency band must be cleared of analog/TDMA activity, both within the cells that are supporting CDMA and within a guard zone surrounding the CDMA service area. The guard zone is necessary to ensure that CDMA activity does not impact service in the remaining analog/TDMA service area.The spectrum swap capability is used when CDMA is being installed and you need to activate and test CDMA without affecting the system during high traffic periods. You can turn CDMA on during low traffic periods for testing, then turn CDMA off and restore analog/TDMA.Up to 150 cells can be swapped between CDMA and analog/TDMA with a 30 minute period. Larger numbers of cells can be swapped but the swap may not complete within 30 minutes. Stable calls in the technology being swapped are camped on for five to 15 minutes (adjustable via RC/V) and are then dropped.Using the following procedure is service affecting. Calls in the area undergoing the swap will be dropped when the camp-on period expires. (Five to 15 minutes—15 minutes is the default value.)Procedure to Swap CDMA Spectrum to/from AMPS/TDMA1.

Initializing, Setting Up, and Using OCNS at CDMA Cell SitesYou can request orthogonal-channel noise simulation (OCNS) setup at Series II Cell Sites with CDMA equipment.OCNS is a CDMA-specific feature in which a special software personality is loaded into one or more CDMA channel elements (CEs) at the Cell Site. OCNS-configured CEs are used to generate radio signals that simulate the effect of multiple users operating in a specified sector on a specified CDMA carrier, so that CDMA system capacity can be estimated in the presence of actual electrical noise from the environment.The following command formats are divided into initial and secondary command requests. Command format 1 is an initial OCNS request. Command formats 2, 3, and 4 are secondary command requests. Use command format 1 before making any secondary requests.You can make as many secondary command requests as you want after making the initial OCNS request.NOTE:After a secondary command request is made, you cannot make another initial command request until command format 3 is used to stop OCNS or the STOP:OCNS;CELL a command is used.!CAUTION:OCNS reduces the amount of available resources for, and interferes with, CDMA traffic.

Fundamental to Lucent’s long term Operations, Administration, and Maintenance (OA&M) strategy is to allow technicians, using information provided to the Executive Cellular Processor (ECP) by the cell sites, to be able to isolate any fault down to an individual piece of equipment. In general, this has involved giving the Executive Cellular Processor (ECP) the ability to correlate different types of error messages and alarms received from the cell sites. In order to support this diagnostic strategy, the Maintenance Request Administrator/Technician Interface (MRA/TI) error messages from the cell are designed to contain and convey as much detail as possible to the Executive Cellular Processor (ECP).
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 17-29Corrective Maintenance using ECP Craft InterfaceThe Maintenance request Administrator Info (MRAINFO) & Technician Interface Info (TIINFO) FieldsThe Maintenance Request Administrator (MRA) and other Radio Cluster Server (RCS) maintenance software, use a field called MRAINFO to specify reason codes and to pass them to other processes within the Radio Control Cluster (RCS) and external to it. In particular, to the Technician Interface (TI), within which the field is defined as TIINFO by the Executive Cellular Processor (ECP). The MRAINFO/TIINFO output message structure is defined as a UCHAR, making it only 8 bits long and able to hold no more than 256 values. The continuing evolution of systems and equipment means that many more error messages have to be accommodated if our maintenance strategy continues to be that of helping the technician isolate a fault down to an individual piece of equipment. Therefore, beginning with R13.0, the MRAINFO/TIINFO field has been redefined as a USHORT, making it 16 bits long, so that it can represent many more error conditions and continue to uniquely identify each one.Increased Length and Values Supported by MRAINFO and TIINFO FieldsTo handle the pre-R13 MRAINFO/TIINFO messages, two functions have been be written and built into the software library so that the entire Executive Cellular Processor (ECP) can have access to them. One function translates the incoming MRAINFO/TIINFO messages into the new 16-bit format, and the other translates the outgoing MRAINFO/TIINFO messages into the new 16-bit format. This feature supports all cell generics and types at the Executive Cellular Processor (ECP). It handles pre-R13.0 compatible cells differently than R13.0 compatible cells, but the logic used will be transparent in future releases.

Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 18-3Alarm Collection and ReportingIntroductionThe alarm and FITS interface (AFI) units (See Figure 18-1), which are part of the RCC (shelf 0) in the primary RCF, monitor both equipment and user-defined alarms. Equipment alarms are gathered from alarm sensors within the AIFs, LAFs, primary RCF, and growth RCFs, while user-defined alarms are gathered from alarm sensors external to the Cell Site equipment. The alarm inputs to the two AFIs are connected in parallel through the backplane of the RCC.The AFI provides an interface for the following alarms:*■One receiver calibration generator (RCG) alarm■Two receive preamplifier alarms■Two reference generator alarms■Six power converter unit (PCU) alarms associated with the primary RCF (18 PCU alarms if both growth RCFs are connected)■Six cooling fan alarms associated with the primary RCF (18 fan alarms if both growth RCFs are connected)■Seven linear amplifier circuit (LAC) alarms via an EIA-422 data link■Eighteen user-defined alarms.NOTE: LAC Maintenance is covered in another section that is entirely dedicated to that subject. It is called, obviously, “LAC Maintenance.”The AFI also provides an interface (See Figure 18-2) for the reference frequency generator (RFG) REF0/REF1 selected status, which indicates which of the two oscillators—reference generator 0 or 1—is active.On each RCF shelf, the alarm signals from the pair of PCUs are wire ORed together to form a single input to the AFI. (For example, the alarm signals from the two PCUs on the RCC shelf are wire ORed together to form the single input PROCPWRL.) All other alarms have individual inputs to the AFI.Except for PROCPWRL, which is internal to the RCC backplane, and the alarm signals from the second growth RCF—RCF2, all alarm signals connect to the RCC backplane via an AYD5 paddleboard connector (See Figure 18-1). The * With ECP Release 7.0 and assuming that the User-Defined Cell Site Alarms (UDA) optional feature is activated, the AFI provides an interface for an additional 12 user-defined alarms and 12 equipment alarms.
Lucent Technologies — ProprietarySee notice on first page18-4 401-660-100 Issue 11 August 2000Alarm Collection and Reportingalarm signals route through the backplane to both the active and standby AFIs, but only the alarms monitored by the active AFI are scanned for alarm conditions.Figure 18-1. Alarm Cabling in the Primary RCFEquipment Alarms There is one alarm associated with the RCG (See Figure 18-2), two alarms associated with the receive preamplifiers (part of the receive filter panels), and two alarms associated with the RFG. As with user-defined alarms, each of these alarms connects to an opto-isolator within the AFI.The “no alarm” state for an RCG or RFG alarm (See Figure 18-3) is with current flowing, while the “no alarm” state for a receive preamplifier alarm is with no current flowing. Unlike user-defined alarms, the polarity for an RCG, RFG, or receive preamplifier alarm is not configurable: each polarity bit is set by on-board firmware to 0 (for no inversion of the alarm signal) or 1 (for inversion of the alarm signal) to achieve the alarm state of logic 0.There is also a REF0/REF1 selected status associated with the RFG. The “REF0 selected” state is with no current flowing, while the “REF1 selected” state is with current flowing. The polarity of the REF0/REF1 select status is not configurable: the polarity bit is set by on-board firmware to 0 to achieve the “REF0 selected” state of logic 1.SHELF 0J110PRIMARY RCF—RCF 0(REAR VIEW)AYD5 PADDLEBOARDAFIs
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 18-5Alarm Collection and ReportingThe AFI monitors six PCU alarms and six fan alarms in the primary RCF (18 PCU alarms and 18 fan alarms if both growth RCFs are connected). Each of the alarms connects to the AFI through one signal line and a common ground return (see “C” and “D” in Figure 18-4, Sheet 2). The “no alarm” state of a PCU or fan alarm is an open (logic 1) between the associated line and the ground return. The polarity for a PCU or fan alarm is not configurable; each polarity bit is set by on-board firmware to 0 (for no inversion of the alarm signal) to achieve the alarm state of logic 0.Linear amplifier circuit alarms are communicated to the AFI via an EIA-422 data link. The active AFI sends address and command messages to the linear amplifier circuits over one line pair, and receives acknowledge and alarm status messages from the linear amplifier units over another line pair.Alarm Status Registers and Scan PointsNineteen 8-bit alarm status registers (0-18) on the AFI store the current alarm information for the equipment being monitored by the AFI. Each bit of the first eleven alarm status registers (0-10) indicates the status of a unique alarm. Alarm status registers 0-2 collect 24 alarms via opto-isolators, while alarm status registers 3-10 collect 64 alarms via direct connections. Prior to ECP Release 7.0, alarm status registers 3-10 collected at most 36 alarms (18 PCU alarms and 18 fan alarms); 28 alarm inputs were unused. With ECP Release 7.0 and assuming that the User-Defined Cell Site Alarms (UDA) optional feature is activated, 24 of the previously unused 28 alarm inputs will be available due to the Increased Cell Alarms enhancement.The remaining eight alarm status registers (11-18) collect LAC alarms via an EIA-422 data link. Each of these registers can store the status of four LACs by allocating a pair of bits to each LAC. Each pair of bits can hold one of four LAC alarm status codes: normal (binary 00), minor (binary 01), major (binary 10), or critical (binary 11). Only alarm status registers 11 and 12 are needed to collect seven LAC alarms.Prior to ECP Release 7.0, the equipment alarm inputs were permanently assigned, that is, the inputs were associated with specific equipment and could not be changed by the user or Cell Site software. With ECP Release 7.0 and assuming that the User-Defined Cell Site Alarms (UDA) optional feature is activated, the equipment alarm inputs will be assigned by Cell Site software based on the Cell Site equipment configuration. The equipment alarm input assignments for the RCF0, RCF1, RCF2, AIF, and LAF will not change.Each alarm is assigned an alarm status register number and bit number (register_number - bit_number) called a scan point. As examples, the scan point for user-defined alarm 0 (user-defined alarms range from 0 through 17) is 0-0, the scan point for reference generator 1 is 2-6, and the scan point for LAC 0 is 11-0 (bit 0 is the first of two bits—bits 0 and 1—holding status for LAC 0).
Lucent Technologies — ProprietarySee notice on first page18-6 401-660-100 Issue 11 August 2000Alarm Collection and ReportingAlarm Reporting to the ECPThe AFI scans the alarm inputs every two seconds to update its alarm memory. When the AFI detects an alarm condition, it sets a flag in the alarm memory. The CPU, which scans the alarm memory every four seconds, reads the flag and responds by transmitting the alarm condition via an X.25 signaling channel to the ECP.The CPU reports an alarm condition only once to the ECP, at the time that the CPU initially senses the alarm. The CPU will also send an “all clear” message to the ECP when the alarm condition either clears itself or is cleared by Cell Site maintenance personnel.

Each side of the RCC has one AFI board. The alarm inputs to the two boards are connected in parallel. The Core Processor reports the status of each alarm to the MSC by a data channel.The AFI board is a buffered interface for the following alarms: ■Eighteen user-assigned alarms ■Five alarms from the Antenna Interface Frame (AIF) ■Twelve alarms from each Radio Channel Frame (RCF) ■Alarms from the Linear Amplifier Frames (LAFs) by an EIA-422 data link. All of the alarms are connected to the Alarm/FITS Interface (AFI) board by an AYD5 adapter board. On the AFI board, the interface for each of the user alarms and the AIF alarms is an opto-isolator with some protective input resistance. These are used for alarm connections made over lines that are 20 feet or greater in length. The design provides one of two alarm device switch arrangements. In both opto-isolator configurations 1 and 2, the “no alarm” condition is with current flowing through the diode element in the opto-isolator; the “alarm” state is with no current flowing. As shown in configurations 1 and 2, the “no alarm” state can be accomplished with either open or closed switch devices. This arrangement also provides a means for detecting a break in a line pair. Each RCF reports the status of 12 alarms to the RCC—6 alarms for shelf power (one for each shelf) and 6 alarms for the fans (one for each fan). Each of these alarms is connected to the AFI board by one line and a common ground return. This is shown by alarm device 3. Each alarm is connected to the input of a tri-state gate in the AFI. For each RCF alarm, the alarm state is with a short (logic low) between the associated line and the ground return. Alarms from the LACs are detected by the active AFI circuit sending address and command messages to the LACs over one line pair and receiving acknowledgment and alarm status messages over another line pair. Cell Site alarm circuits are monitored by the AFI circuit boards on the RCC shelf. Each side of the RCC has one AFI board. The alarm inputs to the two boards are connected in parallel.

Alarms from the LACs are detected by the active AFI circuit sending address and command messages to the LACs over one line pair and receiving acknowledgment and alarm status messages over another line pair. User-Defined Alarms User-defined alarms include miscellaneous alarm conditions, such as fire, forced entry, high temperature, and alarms from ancillary co-located equipment. All the user-defined alarms are connected to the AFIs via one 50-pin, D-type female connector. User-defined alarms are collected in an alarm control panel, which is an optional panel that may be mounted in the FIF or on a Cell Site wall.The AFI derives +12 Vdc from +24 Vdc, which is available on the RCC backplane, using an on-board voltage regulator. The +12 Vdc branches to 24 output pins on the AFI, 18 of which serve as the source voltage for the external alarm switch devices used to implement user-defined alarms. In addition, each of the +12 Vdc output pins connects through the backplane to the corresponding pin on the mate AFI.On the AFI, the interface for each user-defined alarm is an opto-isolator with some protective input resistance. Opto-isolators are used for alarm connections made over lines that are six meters or greater in length. As shown in both “A” and “B” of Figure 18-4, Sheet 2, the design provides for two different types of alarm switch devices: normally closed contact and normally open contact.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 18-15Alarm Collection and ReportingThere are two translations associated with each user-defined alarm: an equipage translation used to enable the alarm and a polarity translation used to invert (if need be) the logic state of the alarm signal. The “no alarm” state for an alarm is with current flowing (see “A” and “B” in Figure 18-4, Sheet 2), which also provides a means for detecting a break in a line pair. The ECP technician must set the associated polarity translation to 1 so that the alarm signal is inverted before being written into the alarm memory. (The equipage and polarity translations for user-defined alarms are specified using the ceqcom2 RC/V form.)A logic 0 in any bit position of the AFI alarm memory indicates an active alarm. That is, within the alarm memory, a logic 0 is the active alarm state, and a logic 1 is the “no alarm” state.The alarm level (critical, major, or minor) and alarm text associated with each alarm are defined by the ECP technician using the User-Defined Cell Site Alarms (UDA) optional feature. For more information, refer to the User-Defined Cell Site Alarms (UDA) Optional Feature document (401-612-057), which is part of the AUTOPLEX Cellular Telecommunications Systems System 1000 Optional Features document (401-900-004).

(An adjunct, as used here, is simply an additional frame, or cabinet, at the base station providing a function that is not essential to base station operation.) The Series IIm T1/E1 Minicell and IImm T1/E1 Microcell will take advantage of the additional 12 equipment alarms to monitor CDPD, Battery, and CDMA adjuncts.Besides providing additional user-defined and equipment alarms, the Increased Cell Alarms enhancement allows 42 existing equipment alarms to be assigned by the cell based on the Cell Site equipment configuration. Hence, upon implementing the Increased Cell Alarms enhancement, a total of 54 (42 plus 12) equipment alarms may be assigned by the cell. The cell recognizes the cell equipment configuration by reading the Cell Site translations data base; it then uses that information to assign the appropriate alarm text strings to the 8-bit alarm status registers in the AFI.The alarm level (critical, major, or minor) and alarm text associated with a user-defined alarm are defined by the ECP technician using the User-Defined Cell Site Alarms (UDA) optional feature. For more information, refer to User-Defined Cell Site Alarms (UDA) Optional Feature (401-612-057).The 42 existing equipment alarms that may be assigned by the cell are:■Twelve alarms normally associated with the primary RCF—RCF0■Twelve alarms normally associated with the first growth RCF—RCF1■Twelve alarms normally associated with the second growth RCF—RCF2■Six alarms normally associated with the RCG, receive preamplifiers, and RFG. (More exactly, there are five alarms plus the RFG REF0/REF1 selected status, which indicates which of the two oscillators—reference generator 0 or 1—is active.)* The Increased Cell Alarms enhancement may be implemented in the Series II Cell Site, Series IIm T1/E1 Minicell, or Series IImm T1/E1 Microcell.

The kit consists of an alarm adapter interface (AAI) AYD10 board, mounting hardware, cabling, and connectors. Since the mounting hardware and cabling depend on the type of Series II base station (traditional Series II, Series IIm, or Series IImm), several different kits are available. The figures show the AAI cabling in the traditional Series II Cell Site; the AAI mounts on top of the primary RCF.The AAI interconnects to the wiring side of the RCC backplane via the frame cabling. The AAI sources +5 Vdc and +24 Vdc from the RCC backplane and shares a common ground connection with the AFI.The AAI provides an opto-isolator interface that is electrically identical to the AFI opto-isolator interface. The AAI contains 24 opto-isolators, one for each of the external alarm switch devices used to implement the additional 24 alarms. The AAI derives +12 Vdc from the +24 Vdc using an on-board voltage regulator, to serve as the source voltage for the external alarm switch devices.A 50-pin, ribbon-type female connector (J2) on the AAI is the interface (See Figure 18-6) for the 24 external alarm switch devices. There are two pins for each alarm input; the additional two pins are circuit ground. Twelve pin pairs are reserved for the additional user-defined alarms (alarms 18 through 29), and twelve pin pairs are reserved for the additional equipment alarms. Each pin pair consists of a positive lead (+12 Vdc) and a negative lead (alarm input).As an alternative to the J2 connector, there are also three terminal blocks (J3, J4, and J5) on the AAI (See Figure 18-7) that may be used as the interface to the 24 external alarm switch devices. The terminal blocks provide an interconnection similar to the alarm control panel residing in the FIF. The J3 terminal block provides 24 positive terminals (+24 Vdc), the J4 terminal block provides 24 negative terminals (alarm input), and the J5 terminal block provides 24 circuit-ground terminals (common). The circuit-ground terminals allow for normally open contact alarm switch devices.An AAI opto-isolator, by sensing the presence or absence of current on the alarm signal input line, places a transistor-transistor logic (TTL) 0 for “no alarm” or 1 for “alarm” onto an alarm signal output line. The 24 alarm signal output lines route through the RCC backplane to both the active and standby AFIs.Of the 28 unused bits in AFI alarm status registers 3-10 (prior to ECP Release 7.0), 24 are now used to collect the additional 24 alarms made available by the Increased Cell Alarms enhancement.

Therefore, two new translations—one for the CDPD adjunct and one for the Battery adjunct—have been created so that the cell can identify the CDPD and Battery adjuncts and assign the appropriate alarms.Support Documentation for the Increased Cell Alarms EnhancementThe Increased Cell Alarms enhancement is described in the User-Defined Cell Site Alarms (UDA) Optional Feature document (401-612-057), which is part of the AUTOPLEX Cellular Telecommunications Systems System 1000 Optional Features document (401-900-004).Procedures for installing the Increased Cell Alarms enhancement hardware in the Series II Cell Site, Series IIm T1/E1 Minicell, or Series IImm T1/E1 Microcell are included in the User-Defined Cell Site Alarms (UDA) Optional Feature document.Directional Setup  The Directional Setup feature allows each sector in a directional Cell Site to have its own setup radio or radios, with each radio assigned a unique setup channel. The setup radios use the same Linear Amplifier Circuit (LAC) and antenna as the voice radios assigned to each sector. The setup radios transmit and receive on the directional faces, therefore eliminating the need for an omnidirectional antenna and equipment in the directional Cell Site. Directional setup, coupled with the wideband LAC, increases the number of voice circuits that a cell can serve since a lower gain omnidirectional setup antenna no longer limits the coverage area. The Directional Setup only provides directional voice while the Omnidirectional Setup provides both directional and omnidirectional voice. Two sparing policies are available to the customer for setup radios. Neither uses receive switches, thus each setup radio is uniquely associated with a given antenna sector and may be located in either single or double height radio shelves. The sparing policies are as follows: Providing full duplication of each setup radio without receive switches (on-line spares) Using the recent change/verify process for the manual radio reconfiguration without receive switches to change a voice radio to a setup radio (off-line spares). Directional Setup is required for Microcells. Directional Setup also supports Mobile-Assisted Handoff for Dual-Mode Mobile Station (DMMS) operating in the digital mode by providing a continuous fixed power setup signal that the DMMS measures to determine the best serving face.

See Figure 18-8. At the Radio Channel Frames (RCFs), there are two distinct RF receiver interface configurations, the switchable antenna connection and the fixed antenna connection. In Release 4, the switchable antenna configuration is used only in the upper 2 radio shelves (shelves 1 and 2) of the P-RCF to support setup and locate receive antenna switching needs. A diagram of this configuration is given in Figure. Signals from the antenna interface enter the RCF by the common port of a 1:9 power divider located in the interconnection assembly at the top of the frame. An output port from as many as 4 (omni, alpha, beta, and gamma) power dividers is cabled to an RF switch board located in shelf 1. The switch consists of a 4 by 12 matrix which allows any of the 12 radios on the shelf to have its receive inputs connected to any 1 of 4 antenna faces. The switch matrix is controlled by logic outputs from the Radio Channel Units (RCUs) themselves. The shelf contains 2 identical RF switch boards, one for Diversity 0 and one for Diversity 1. Shelf 2 is cabled in an identical manner as described above. In a 6-sector configuration, shelf 2 allows receive antenna switching among the omni, delta, epsilon, and zeta faces.

This amplifier type was hard-coded into an amplifier alarm table that was created specifically for that particular type of amplifier. Within that table each type of alarm pertaining to that specific amplifier was hard-coded and pre-defined. Also hard-coded and pre-defined was the alarm text string for each alarm type in the table.There were multiple amplifier alarm tables for multiple types of amplifiers. However, at cell initialization only one amplifier alarm type/table was selected, based upon the type of amplifier the cell was equipped with. Once selected, the hard coded alarm table became the template for all amplifier alarm reports, including the text strings. While this method was quick and simple in application, it only recognized one single type of amplifier for the entire cell, so all cell amplifiers had to be of the same type. Alarm scanning could not support a cell that had 2 or more different types of amplifiers.To address these problems, the AS software has been redesigned and is being introduced in ECP Release 11.0 and CDMA Release 6.0. The current release of the AS redesign supports:1. High-power Transmit Power Amplifier (HTPA) used with the CDMA Cellular minicell 2. PCS CDMA Amplifier (PCA) and High-power PCS CDMA Amplifier (HPCA) used with the CDMA Personal Communications Services (PCS) minicell.With the introduction of the AS Redesign feature, the amplifier alarm table is dynamically populated, according to the amplifier type, on a per amplifier alarm address basis. Any amplifier unit whose amplifier type is supported can be assigned to any amplifier address. The new populated alarm table does not hard code the information of the physical amplifier unit number and the corresponding alarm text. Therefore, it is possible to make the amplifier unit self-configuring. Although, the AS Redesign feature begins with one type of amplifier, the CDMA Transmit Unit (CTU) / Receive Unit (RU), the long term goal is to layout a common architecture such that future development can be used to eliminate all hard coded alarm tables and to support mixed type amplifier configurations.The AS Redesign feature in this release supports only CDMA PCS and CDMA Cellular Minicell technologies, such as the cellular CDMA Adjunct to small cells. It does not affect the existing hard-coded alarm processing used by the Series II AMPS, TDMA, and CDMA.
Lucent Technologies — ProprietarySee notice on first page18-22 401-660-100 Issue 11 August 2000Alarm Collection and ReportingPreviously, Alarm Scanning (AS) software for alarms at the Cell Site and the Mobile Switching Center used hard-coded tables to assign not only the Alarm and FITS Interface (AFI) alarm addresses, but the alarm text string for each internal device unit (e.g. amplifiers) as wellWith the introduction of this feature, the Cell Site software provides a generic reporting function, so that all amplifier alarm specific assignment information (amplifier unit number/amplifier alarm address and alarm text string assignments) can be retrieved from the cell translation data/Executive Cellular Processor (ECP) database and ECP global data owned by the AS RTR Unix process. The goal is to provide a long-term solution for amplifier alarm reporting mechanism with minimum effort whenever a new amplifier/device or new amplifier alarm configuration is added to the Cell Site. Constructing the alarm text string for all amplifier alarm messages at the ECP AS RTR Unix process makes it possible for the alarm reports at the Cell Site and alarm reports from the Executive Cellular Processor (ECP) to be synchronized. In particular, the following 2 reports are synchronized:1. Spontaneous Amplifier Alarm Report, that is initiated from the cell site2. AS Office Alarm Summary Report, that is directly processed by the ECP in response to an office alarm summary request.As a result, this feature will solve any incorrect AS query problem due to the amplifier alarm hardcoded design that fails to handle different amplifier alarm address and corresponding amplifier unit assignment. The AS redesign is intended to establish a common platform that could provide groundwork to support all technologies. When the feature is incorporated in the AMPS/TDMA applications, future implementation of new technologies can be minimized. However, the feature is currently applied to only CDMA applications. Scope Alarm Scanning Redesign depends on the existing AUTOPLEX System amplifier alarm infrastructure and alarm reporting capabilities defined in the cell site and MSC OA&M documents. The feature adds the following amplifier alarm related capabilities:■Provides amplifier alarm address assignment flexibility for the amplifier alarm hardware design; any combination of currently supported amplifiers of the same or different types in the Radio Channel Frames (RCF) - Primary and Growth Frames 0 and 1 as well as CDMA adjunct. The reconfiguration of the currently supported amplifiers can be performed via the Recent Change and Verify (RC/V) interface without Software Update (SU)/Retrofit.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 18-23Alarm Collection and Reporting■Allows the reuse, or reassignment, of existing amplifier alarm states (4-bit alarm data representations) and their alarm descriptions (alarm text) to a different amplifier/type with minimum effort.■Allows all amplifier related alarm reports (alarm office summary report, amplifier alarm query response, and spontaneous alarm scan report) to be synchronized with consistent amplifier unit number, amplifier name, and alarm text string for the same alarm status.■Allows a single or multiple amplifier alarm status of the PCS CDMA Minicell CDMA Transmit Unit (CTU) / Receive Unit (RU) amplifier to be reportable by the MSC.Customer Perspective This feature provides a new platform for more amplifier alarm related applications/configurations [e.g. Cellular CDMA adjunct to Series IIm (Minicell)/Series IImm (Microcell)]. Features The alarm scanning redesign is an on-going OA&M effort targeted for all technologies as well as all various alarm types (amplifier, AIF, power/fan, equipment, and user alarms).The ECP/Cell Site release for this feature is backward compatible with earlier release. The existing alarm reporting capabilities are not affected. The new ECP release supports both new and old cell site releases.Cell Site Functions Dynamically Populated Amplifier Alarm TableThe amplifier unit number and alarm text string assignments were previously hardcoded in the cell amplifier alarm tables on a per alarm address basis. The hardcoded design led to the propagation of cell alarm tables, which are difficult to maintain, and fail to support amplifier alarm address reconfiguration. The dynamically populated alarm table is therefore required to provide alarm address flexibility and self-configuration.The amplifier alarm address is sent to the ECP and is used as logical amplifier unit number for all amplifier alarm reports. An Amplifier alarm address has 2 representations:1. Denoted as offset/register number and bit number. 2. Referred as circuit ID with a range of 0-31 in the ceqcom2 RC/V form).The amplifier alarm table is dynamically populated according to the amplifier type on a per amplifier alarm address basis for CDMA Cellular Minicell and PCS CDMA Minicell. The new populated alarm table does not hardcode the information of the alarm text and physical amplifier unit number.
Lucent Technologies — ProprietarySee notice on first page18-24 401-660-100 Issue 11 August 2000Alarm Collection and ReportingAs it is populated on a per amplifier alarm address basis, any amplifier unit with a supported amplifier type is assignable to any amplifier address. The dynamically populated table allows the amplifier unit to configure itself.NOTE:For the TDMA, Series II CDMA and AMPS cells, the system uses the existing hardcoded amplifier alarm table for alarm processing. Because at this point, this feature is for the CDMA Minicell technology only, the existing hardcoded alarm processing for other technologies (TDMA, Series II CDMA, AMPS) is not be affected.The dynamically populated amplifier alarm table supports the Cellular Minicell Adjunct to the Series IIm (Minicell) configurations to allow the coexistence of mixing Series IIm (Minicell) ICLA and CDMA Cellular Minicell HTPA amplifier alarm types.The amplifier alarm table supports the Cellular MiniCell Adjunct to the Series IImm (Microcell) configurations to allow the coexistence of mixing Series IImm (Microcell) and LAC amplifier alarm types in the same cell.MSC Functions Amplifier Alarm Reporting/QueryEvery 4 seconds, the AFI polls the alarm status of each amplifier circuit through the EIA-422 bus interface message containing the amplifier alarm address. The Alarm Scanning Process in the Cell Site software then reads the alarm data associated with each amplifier alarm address and reports to the MSC.Previously, amplifier alarm reporting and query functioned as follows: The physical amplifier unit number was hardcoded as part of a text string in the cell site amplifier alarm table. It was not retrievable by the Cell Site/ECP software. The amplifier alarm report, requested by the Cell Site software or technician worked well when the amplifier alarm address lined up with the physical amplifier unit number (e.g. alarm address x used by physical amplifier unit x) for traditional Series II LAC amplifiers. However, the physical amplifier unit number could be different from the amplifier alarm address number to which the amplifier unit was assigned. Because the Cell Site software was not capable of communicating to the remote amplifier controller, it could not relate the alarm status from each amplifier alarm address to the remote amplifier unit being queried.For the PCS CDMA Minicell, the alarm assignment of the CDMA Transmit Unit (CTU) / Receive Unit (RU) amplifiers begins with amplifier alarm address 29. The alarm status of CTU physical amplifier unit 0 is passed on to the RCC through amplifier alarm address 29, address 30 for CTU physical amplifier unit 1, etc. The physical amplifier unit number was previously hardcoded to the spontaneous alarm report at the ROP. When the technician was informed that the physical
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 18-25Alarm Collection and Reportingamplifier unit 0 was at the alarm state, he/she had to query the amplifier alarm status of this alarmed amplifier by entering the amplifier alarm address 29 in the OP:CELL-LAC alarm input command.This inflexibility of the user interface has been corrected by defining a logical amplifier unit number for each amplifier unit associated with an amplifier alarm address and providing the logical amplifier unit number to the physical amplifier unit mapping. But, to provide the logical to/from physical amplifier unit number mapping and configuration information to the RC/V would have a great impact on the existing amplifier installation procedure. In order not to introduce any additional amplifier installation overhead, such as RC/V administration work, the following statements apply:■The Existing amplifier alarm address (referred as circuit ID in the RC/V form) is the logical amplifier alarm unit number for the associated amplifier unit.■ The Physical amplifier unit numbering will no longer be supported by the AS reporting software.The technician will be instructed to locate the physical amplifier unit based on the sector, carrier, and radio Baseband, Bus and Analog (BBA) trio circuit information given in the ECP database. Consequently, all amplifier alarm input/output messages and Status Display Page will all use the logical amplifier unit number to report the amplifier alarm status. NOTE:The Baseband Combiner and Radio (BCR), Bus Interface Unit (BIU) and Analog Conversion Unit (ACU) trios are known collectively as the BBA. Upon detecting a non-sanity related amplifier alarm, the cell derives the amplifier alarm state from the amplifier type and the value of the four scanning point bits as defined in the HW spec/arch document and send the MSC the alarm address (offset #, bit #), alarm level/severity, alarm state summary (off normal or normal), and alarm state.Four amplifier alarm states for the HTPA amplifier and 6 amplifier alarm states for the PCA/HPCA amplifier should be reported.With this release, the following amplifier alarms are supported:Four alarm states are supported for the Linear Amplifier Circuit (LAC) alarm:0 - None1 - LAC minor alarm2 - LAC major alarm3 - LAC critical alarm.
Lucent Technologies — ProprietarySee notice on first page18-26 401-660-100 Issue 11 August 2000Alarm Collection and ReportingSix alarm states are supported for the PCS CDMA MiniCell:0 - None1 - CDMA Transmit Unit (CTU) failure-critical alarm, 2 - Single Receive Unit (RU) failure-major alarm3 - CTU and single RU failure-critical alarm4 - Both RU failure-critical alarm5 - CTU and double RU failure-critical alarm. The content of the interface message is not changed, except the alarm text string to be replaced by the amplifier alarm state.The MSC then constructs the spontaneous scanning amplifier alarm report to provide the following information:■Cell Number■Alarm Scan Point (offset# & bit#)■Logical Amplifier Unit number converted from alarm scan point■Amplifier name associated with the amplifier type■Alarm description (text string) associated with the state and amplifier type■Alarm summary state (The "OFF NORMAL" alarm condition indicates a hardware/communication failure).The technician originated office alarm summary (OP:ALARM) report, in addition to other data, contains the alarm scan point and the "OFF NORMAL/NORMAL" alarm summary state.The amplifier name on a per amplifier type basis and alarm text string on a per amplifier type and amplifier alarm state basis is assignable through ECP global data owned by ECP AS Unix process.Up to 16 amplifier alarm states per amplifier type as well as up to 70 alphanumeric characters per alarm text string is supported.Upon receiving the amplifier sanity failure message from the cell site, the ECP, rather than the Cell Site, constructs the following alarm text string on a per system basis for the amplifier sanity failure reporting: "SANITY ALARM COMMUNICATION FAILURE." The logical amplifier unit number (0-31) and amplifier alarm state of each alarmed amplifier in the cell site is delivered to the MSC, on Status Display Page (SDP) 2136, showing display/update every 15 seconds.The sanity failure is displayed as it is now.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 18-27Alarm Collection and ReportingThe basic alarm state (on or off) per alarm unit on the SDP 2136 page is supported for amplifier units of a new amplifier type reusing an existing amplifier alarm state (4-bit alarm data representations).The MSC also sends to the cell site the logical amplifier unit number (0-31) for the individual amplifier OP query request from the technician.A new AU option for the OP:CELL command is allowed to query the alarm status of non-LAC type amplifiers.One "REPT:CELL-ALARM SCANNING" report showing both CDMA Transmit Unit (CTU) and Receive Unit (RU) alarm status is sent to the ROP.The LAC alarm data is in the form of 4 bits labeled W, C, Bit 1, and Bit 0. These 4 bits in the alarm response message are used to indicate the status of the CTU and RUs. Because the hardware reports both CTU and RU status simultaneously, one report is generatedPrior to this feature, the physical amplifier unit number (0), rather than the logical amplifier unit number (29), was indicated in all amplifier alarm related output messages (i.e. alarm office summary report, amplifier alarm query response report, and spontaneous scan output report) at the ROP for the CDMA PCS Minicell. In order to minimize the impact to this existing user interface, the physical amplifier unit number will be provided as well in all amplifier alarm output messages.Without logical to/from physical amplifier unit number mapping information in the RC/V, this would have to be done through a hardcoded method in the TI. Note that providing both physical and logical amplifier unit numbers is for PCS CDMA Minicell only, not for CDMA Cellular Minicell adjuncts to the Series IIm (Minicell) / Series IImm (Microcell). This would be an interim solution until input from customers regarding the amplifier unit physical numbering for the mixed amplifier cell configuration is obtained.CDMA Transmit Unit (CTU) and Receive Unit (RU) Separate AlarmsThe CDMA Transmitter unit (CTU) has the following alarm conditions: ■Transmit (Tx) up-converter synthesizer out-of-lock■Transmit (Tx) amplifier alarm (amplifier malfunction, amplifier over-temperature, and over current). If any of these alarm conditions occur, the Radio Control Complex (RCC) is informed.Each Receive Unit (RU) has 2 alarm conditions: ■Low Noise Amplifier (LNA) failure
Lucent Technologies — ProprietarySee notice on first page18-28 401-660-100 Issue 11 August 2000Alarm Collection and Reporting■RU down converter synthesizer out-of-lock. If either of these alarm conditions occur, the RCC is informed.For the PCS CDMA Minicell, the receiver unit alarm was reported as part of the CTU transmit amplifier status message. Any failure occurring on both diversity receive units would result in a critical alarm. Currently, RU and CTU alarms are accurately reported at the ROP, but incorrectly reported in the "OP:ALARM,ALL" or "OP:CELL-LAC" input command response. This feature will report the CTU critical alarm, single receiver unit major alarm and double receiver unit critical alarm separately on the display pages and the ROP.A single receiver unit alarm indicates the loss of half the diversity pair and traffic capacity limitation while the double receiver unit alarm indicates a total loss of the receiver diversity pair. Most of all, it allows the multiple amplifier alarm (state 3 and state 5) to be reported.This feature will also provide a CTU/RU status page (new 2136 page) to display the status of all CTUs/RUs at a single PCS CDMA Minicell. Because the receiver unit alarm message from the alarm circuit does not pass the affected RU number, the major (yellow background for single RU failure) and critical (red background for double RU failure) indicators will be highlighted on the pair of diversity amplifiers. Upon being informed of a single amplifier alarm, the technician has to check the LED indicator at the Alarm Control Board's faceplate to determine which RU causes a single receiver alarm. Furthermore, to facilitate amplifier maintenance, the sector number and carrier number associated with the CTU and the sector number associated with the RU pair must also be displayed. The display page supports the configurations of 1 carrier-6 sectors, 1-3 carriers-3 sectors, 1-9 carriers-omni. The CTU/RU numbering will be based on the logical amplifier unit number.This feature provides the alarm reporting capabilities for each CTU and each pair of the RU. These include new "OP:CELL-CTU" and OP:CELL-RU" input command options, the modified "OP:ALARM,ALL" output report and spontaneous alarm reports (REPT:CELL a ALARM SCANNING).The RCG icon in the 2131 page are marked "uneq" for CDMA Cellular Minicell and PCS CDMA Minicell. An RU (PCS CDMA Minicell Receive Unit)" icon reflects the status summary of both down-converters/receive diversity pair based on the 2 RUs in the diversity receive paths of the PCS CDMA Minicell. A single receive diversity alarm will be displayed with a yellow background to indicate the loss of half the diversity pair and traffic capacity limitation while a double RU alarm will be in a red background to indicate a total loss of the receive diversity pair.

Lucent Technologies — ProprietarySee notice on first page20-2 401-660-100 Issue 11 August 2000AMapping Status Display Page Unit Numbers to HardwareIntroductionThis section shows how logical unit numbers on the ECP status display pages map to their physical counterparts in the Series II Cell Site. For example, logical unit DS1 0 on the 2134 - Cell DS-1 Unit Status page maps to a DS1 or DFI hardware unit seated in shelf 3, slot 12, of the primary RCF. The mapping is established through translations, or system-configuration parameters, which hold the static data determining the behavior of the Cell Site.The recent change and verify (RC/V) subsystem at the ECP is used to build (or update) the Cell Site translations data base, that is, assign specific attributes to the various translations. Specifically, the RC/V ceqcom2 form is used to establish how Series II Cell Sites are equipped, that is, establish the logical-to-physical mappings of hardware units for each and every Series II Cell Site.In the current RC/V implementation, some logical-to-physical unit mapping is fixed and cannot be changed by the user: the mapping is the same for each and every Series II Cell Site sold by Lucent Technologies. (DS1 0 is an example of this type of mapping.) Other logical-to-physical unit mappings are not fixed and can be established as the user sees fit. For the latter case, the only way to identify the physical location (frame, shelf, slot) associated with a logical unit number on the status display page is to consult the ceqcom2 form.Logical-to-Physical Mappings of Generic Cell Site UnitsThe mappings in Figure 20-1 show how the CSC (RCC) and certain DS1 and CAT logical unit numbers on the status display pages map to their physical counterparts in the primary RCF. CSC 0 and CSC 1, DS1 0 and DS1 1, and CAT 0 and CAT 1 are fixed and cannot be changed by the user. The other two DS1s residing in shelf 0, slot 21, and shelf 5, slot 14, serve as examples of logical-to-physical mappings established by the user; they can be assigned any DS1 logical numbers within the range 2 through 13.The range for DS1 logical numbers is 0 through 13 since a fully equipped, non-CDMA, Series II Cell Site can hold up to 14 DS1s. Seven DS1 slots connect to TDM bus 0 (TDM0) (See Figure 20-2), and seven DS1 slots connect to TDM bus 1 (TDM1).NOTE:TDM buses are always installed "red stripe up."A DFI may reside in any slot reserved for the DS1. When DS1 and DFI units are equipped using RC/V, both units are given “DS1” logical numbers. With few exceptions, there is no distinction between DFI and DS1 units on the status display pages; both are lumped together under the “DS-1” heading.

The range for CAT logical numbers in a non-CDMA Cell Site is 0 through 3. The active (on-line) CAT, CAT 0 or CAT 1 (See Figure 20-3), provides the TDM bus clocks for TDM0. The active CAT, CAT 2 or CAT 3, provides the TDM bus clocks for TDM1. NOTE:TDM buses are always installed "red stripe up."

Logical-to-Physical Unit Mapping for the CAT (Sheet 3 of 3)Logical-to-Physical Mappings of CDMA-Specific Cell Site UnitsThe mappings in Figure 20-6 and Figure 20-8 show how the CDMA logical unit numbers on the status display pages map to their physical counterparts in the Series II Cell Site. For example, as highlighted in reverse video in Figure 20-6, logical unit CCC 7 on the status display page maps to the CCC seated in shelf 0, slot 12, of CDMA growth frame RCF1. In the current RC/V implementation, the logical-to-physical unit mapping for CDMA units is fixed and cannot be changed by the user.Up to two CDMA growth frames, CDMA RCF1 and CDMA RCF2, may reside at a Series II Cell Site.CCUs are addressed using a fixed numbering scheme that associates each CCU with its particular CCC.

The user could associated other “DS1’ logical numbers with those DFIs, but the DFIs must be physically located as shown in the Figure 20-10. DFIs are required for CDMA operation. (Slot 24 of shelves 2 and 3 of the CDMA growth frame is reserved for the DFI.)The range for CAT logical numbers in a CDMA Cell Site is 0 through 5. CAT 4 and CAT 5 are always SCT units. (Slot 24 of shelves 0 and 1 of the CDMA growth frame is reserved for the SCT.)On the status display pages, SCT and CAT units are lumped together under the “CAT” heading. A c displayed next to a CAT logical number indicates a CAT board, and an s displayed next to a CAT logical number indicates a SCT board. When equipping SCT and CAT units using RC/V, SCT units are configured for GPS timing, while CAT units are configured for no GPS timing. RC/V is not used to configure a SCT for TDM bus timing; that configuration is accomplished manually via a TDM enable switch on the wiring side (rear side) of the backplane associated with the installed SCT. The active (on-line) SCT provides CDMA reference signals for the entire CDMA growth frame in which it resides.Upon comparing the two figures, you will notice a difference in TDM1 cabling between the AMPS/TDMA RCF2 and the CDMA RCF2. The TDM1 cabling in the AMPS/TDMA RCF2 starts at the bottom of the frame, whereas the TDM1 cabling in the CDMA RCF2 starts at the top.NOTE:TDM buses are always installed "red stripe up."

Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-3CDMA MaintenanceIntroductionThis section describes the code division multiple access (CDMA) system as implemented in the Series II platform and presents trouble-clearing procedures to correct faults pertaining to CDMA Cell Site hardware units. It also presents cursory trouble-clearing procedures to correct faults pertaining to CDMA voice-processing hardware units at the 5ESS®-2000 Switch DCS.CRTU and CDMA Functional Testing The CDMA radio test unit (CRTU) is used by the RCC to verify proper operation of CDMA radio equipment at a Series II Cell Site, Cellular CDMA Minicell, or Personal Communications Services (PCS) CDMA Minicell. The CRTU can test 8- or 13-kbit/s CDMA vocoder operation.The CRTU supplements Cell Site diagnostic testing with functional testing. CDMA functional testing verifies that the network is able to originate mobile calls over the cell CDMA channels and that all cell CDMA radio equipment is operational. The CRTU can automatically test every idle (in-service and non-busy) CDMA traffic channel element (CE) in the cell without human intervention.There are two types of CDMA functional tests:1. Overhead channel functional tests, which verify that the pilot/sync/access (P/S/A) CEs and page CEs are operational.2. Traffic path functional tests, which verify that the CDMA traffic CEs are operational.The CDMA functional tests require that the CRTU set up test calls using the mobile station test (MOST) feature.The CRTU has a TDM bus connection to the RCC, and RF connections through the radio switch panel (RSP) to the directional couplers of the transmit and receive filter panels at the antennas (See Figure 21-1). NOTE:TDM buses are always installed "red stripe up."
Lucent Technologies — ProprietarySee notice on first page21-4 401-660-100 Issue 11 August 2000CDMA MaintenanceFigure 21-1. High-Level View of the CRTU Test SystemCRTU Components The CRTU consists of two hardware components (See Figure 21-1): the CRTU interface (CRTUi) and the CRTU module (CRTUm). The CRTUi is a plug-in board installed in the primary RCF through which the RCC communicates with an IS-95B compliant mobile station in the CRTUm. From an RCC perspective, the CRTUi and CRTUm together look like a single maintenance unit, just like the RTU or TRTU.The CRTUi contains the firmware needed to run the CDMA functional tests. In response to functional test messages from the RCC, the CRTUi carries out the specified actions and returns the test information to the RCC. The message exchange is through TDM0.NOTE:The term CRTU will be used in this document except when it is necessary to distinguish between the CRTUi and CRTUm components.TXANTRCCCDMAAMPSLAC &AIFRX ANTsDIV0DIV1RSPCRTUmCRTUiTXANTRCCCDMAAMPSLAC &AIFRX ANTsDIV0DIV1RSPCRTUmCRTUi5ESS®-2000 SWITCH DCSTO/FROMECP COMPLEXOMPTIME SLOTINTERCHANGEUNITPCM PACKET PIPEDIGITAL TRUNK UNITT1 LINESPSTNMSCFRAME RELAYPROTOCOLHANDLERMOSTTONEGENERATORDIGITALFACILITIESINTErfACEDIGITALFACILITIESINTErfACEPROTOCOLHANDLERFOR VOICECRTUmCRTUiDEFINITIONS:CDMA RADIO TEST UNIT MODULECDMA RADIO TEST UNIT INTErfACE MOSTRSPMOBILE STATION TEST (FEATURE)RADIO SWITCH PANELSERIES II Cell SiteSERIES II Cell SiteDFIDFIT1 LINESCD M A PATHTDMBUSTDMBUS RFTDMBUSTDMBUS RF
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-5CDMA MaintenanceThe CRTUi communicates with the CRTUm through an EIA-422 asynchronous data link. It is over this data link that the CRTUi, under the direction of the RCC, instructs the CRTUm to perform individual CDMA functional tests, and over which the CRTUi and RCC collect the test results. Included with the four-wire EIA-422 data link are two control leads. One control lead allows the CRTUi or RCC to turn off the CRTUm by disabling power to the CRTUm. The other control lead is reserved for future use.The CRTUi communicates with the RSP through an RSP control board (RCB)* and a second EIA-422 asynchronous data link. It is over this data link that the CRTUi, under the direction of the RCC, instructs the RSP to set its internal RF switches to connect to the desired RF path (See Figure 21-2).An AYD12 paddleboard (circuit board), installed on the wiring side of the CRTUi slot pinfield, provides the two physical connectors needed to interconnect the CRTUi with the CRTUm and the RCB.NOTE:Be aware that the port designations J1 and J2 on the PCS CDMA Minicell RSP map to port designations J2 and J1 on the Series II Cell Site RSP or Cellular CDMA Minicell RSP—the port designations are reversed. As clarification, J1 on the PCS CDMA Minicell RSP allows access to the transmit filter panels, whereas J1 on the Series II Cell Site RSP allows access to the receive filter panels.The CRTUi faceplate has three light-emitting diode (LED) indicators, one red, one yellow, and one green. Their meanings are as follows:Red LED 0Controlled by the CRTUi; lighted during the self-test initiated upon powerup or after a reset and goes off after successful completion of the self-test; lighted during normal operation if the CRTUi has a board error or is insane.Yellow LED 0Controlled by Cell Site system software; Lighted during non-volatile memory (NVM) update.Green LED 0Controlled by the CRTUi; Lighted when a CDMA functional test is executing.* Since the Series II Cell Site has both CDMA and AMPS radios, the RCB is needed so that both the CRTU and RTU can access the RSP. No RCB is needed for the Cellular CDMA Minicell or PCS CDMA Minicell since neither contains AMPS (or TDMA) radios.

Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-7CDMA MaintenanceExecutive Cellular Processor FormThe ecp form contains the ECP information used to process calls, make service measurements, and provide automatic message accounting (AMA) information. The values specified here will be used for each cell served by this ECP unless other values are specified on an individual cell basis using the RC/V cell forms, such as ceqcom2. The values on the RC/V cell forms for an individual cell take precedence over the ECP values.The following new fields have been added to the “CDMA Information (Non-Power Control)” screen of the ecp form:■Overhead Channels Functional Test Interval (min)—The interval between automatic requests of the CDMA overhead channel functional test.The interval value for the routine (scheduled) overhead channel functional test can be set to any value within the range 1 - 1440 minutes in increments of 1 minute. The default interval value is 25 minutes.Value 1439 has special meaning. Setting the interval value to 1439 disables (inhibits) the execution of routine CDMA overhead channel functional tests and prevents the Cell Sites from reporting an off-normal alarm to the ECP. (Unlike the INH command, which does cause the targeted Cell Site to report an off-normal alarm to the ECP. The INH command is intended for short-term disabling—inhibiting.)(A Cell Site off-normal alarm indicates one or more of the following off-normal states at the cell: inhibited, alarmed, out-of-service, overload, or initializing.)■Traffic Path Functional Test Interval (min)—The interval between automatic requests of the CDMA traffic path functional test.The interval value for the routine (scheduled) traffic path functional test can be set to any value within the range 1 - 1440 minutes in increments of1 minute. The default interval value is 60 minutesValue 1439 has special meaning. Setting the interval value to 1439 disables the execution of routine CDMA traffic path functional tests and prevents the Cell Sites from reporting an off-normal alarm to the ECP.■Traffic Path Functional Test MOST DN—A special directory number dialed by the CRTU during CDMA overhead channel and traffic path functional testsMOST DN stands for mobile station test (MOST) directory number (DN).
Lucent Technologies — ProprietarySee notice on first page21-8 401-660-100 Issue 11 August 2000CDMA MaintenanceCell Equipage Common FormThe ceqcom2 form contains information concerning Cell Site equipment configuration, status, and maintenance-related parameters for an individual Series II cell. The values on the ceqcom2 form take precedence over the values on the ecp form.The following new fields have been added to the “Radio Test Unit” screen of the ceqcom2 form:■CDMA RTU - Status—Used to equip a CRTU at a Series II cell.The allowed values for the CDMA RTU (CRTU) status field are unequipped, equipped, and growth. The default value is unequipped. When equipped, the CRTUi slot location is fixed at frame 0, shelf 0, slot 15.■Functional Test Intervals:—CDMA Overhead Channels (min)—CDMA Traffic Path (min)The interval value for the routine (scheduled) overhead channel functional test and the interval value for the routine (scheduled) traffic path functional test can be set to any value within the range 1 - 1440 minutes in increments of 1 minute. There are no default interval values on the ceqcom2 form.Value 1439 has special meaning. Setting the interval value to 1439 for CDMA Overhead Channels (min) disables the execution of routine CDMA overhead channel functional tests and prevents the Cell Site from reporting an off-normal alarm to the ECP. Likewise, setting the interval value to 1439 for CDMA Traffic Path (min) disables the execution of routine CDMA traffic path functional tests and prevents the Cell Site from reporting an off-normal alarm to the ECP.An interval value specified here will override the interval value (including 1439) specified on the ecp form. However, when an interval value is null (no entry) on the ceqcom2 form, the interval value on the ecp form is used by the cell.Subscriber and Feature Information FormThe sub form contains information for the mobile subscriber, including any custom calling features the subscriber may have.The following new values have been added to the Mobile Directory Number Type field of the sub form:■y for CDMA RTU (CRTU) test mode mobile■b for CDMA test mode mobile.There are two types of CDMA MOST calls: those that are originated by the CRTU, and those that are originated by any other IS-95 compliant test mobile. Both the ECP and RCC can distinguish between the two types of MOST calls because
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-9CDMA Maintenanceeach type has a unique Mobile Directory Number Type value (y, b)* designated via the sub form. Both types of CDMA MOST calls use the same special directory number specified in the Traffic Path Functional Test MOST DN field of the ecp form.Cell Equipage Component Location FormThe ceqcloc form is a review-only form containing information about how Series II cells are equipped. It contains the physical layout information for each slot on each shelf in each frame.The following new equipment assignment can be reviewed on the ceqcloc form: the CRTUi at frame 0, shelf 0, slot 15. After you enter the Series II cell number a (1-222), frame 0, shelf 0, and slot 15 in the ceqcloc form, the Component Type field of the form should display CDMA RTU.Status Display Page Changes to Support the CRTUCertain indicators and commands have been added to the following status display pages to support the CRTU:■2131 - Cell Equipment Status page■2132 - Cell Software Status page.2131 - Cell Equipment Status Display PageThe 2131 page displays the configuration of Cell Site hardware units and provides a status summary of each unit or group of units for an individual Cell Site.The CRTU indicator and four additional page commands† have been added to the 2131 page. You can use the additional page commands to execute any of the following operations on the CRTU:■Remove CRTU from service■Restore CRTU to service■Diagnose CRTU■Generate status output message report on CRTU.The result of the remove, restore, diagnose, or generate-status page command is identical to entering the RMV, RST, DGN, or OP command at the ECP Craft Shell prompt or at the command line at the bottom of a status display page.* The values y and b are literal values, not variables. You enter y in the Mobile Directory Number Type field of the sub form for the CRTU.†Page commands are also known as poke commands.
Lucent Technologies — ProprietarySee notice on first page21-10 401-660-100 Issue 11 August 2000CDMA MaintenanceThe CRTU can be in one of four states (active, out-of-service, unequipped, or growth) as indicated by the video state of the CRTU indicator:1. act (steady black on green)2. oos (steady black on red)3. uneq (steady magenta on black)4. grow (steady white on magenta).2132 - Cell Software Status Display PageThe 2132 page provides software status indicators and allow/inhibit page commands for the following Cell Site software processes:■Audits■Audit/HEH (hardware error handler) output■Boot (initialization)■Call processing■Forward setup channel control■Routine functional tests■Interrupts■Phase monitoring■Routine diagnostics■Diversity error imbalance output.The result of an allow or inhibit page command is identical to entering the ALW or INH command at the ECP Craft Shell prompt or at the command line at the bottom of a status display page.Inhibiting a Cell Site software process causes the affected cell to send an off-normal alarm to the ECP. (A steady black on white CELL status indicator on the status display pages means that at least one Cell Site in the system is in the inh state.) A subsequent allowing of the Cell Site software process causes the affected cell to send an “all clear” message to the ECP, thereby clearing the cell off-normal alarm at the ECP.Two menu commands for the CDMA functional tests have been added to the 2132 page: oc for overhead channel tests, and tp for traffic path tests. You can use the additional menu commands to:■Allow or inhibit the execution of routine (scheduled) overhead channel functional tests.■Allow or inhibit the execution of routine (scheduled) traffic path functional tests.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-11CDMA MaintenanceEntering the menu command to allow or inhibit the execution of a routine CDMA functional test when the test is disabled via translations has no affect. You must first revisit the RC/V ecp or ceqcom2 form and specify an interval value other than 1439.
Lucent Technologies — ProprietarySee notice on first page21-12 401-660-100 Issue 11 August 2000CDMA MaintenanceCommand and Report Changes to Support the CRTUSeveral technician interface input commands and reports have been modified to support the CRTU. Most but not all of the modified input commands are listed below:■ALW:CELL a,FT OC - Allows the execution of routine (scheduled) overhead channel functional tests at cell a (1-222).(Entering the ALW:CELL a,FT OC command when the CDMA overhead channel test is disabled via translations has no affect. You must first revisit the RC/V ecp or ceqcom2 form and specify an interval value other than 1439, then enter the ALW command.

Enter the following commands to inhibit the execution of routine CDMA functional tests:INH:CELL a,FT OCINH:CELL a,FT TP2. Install the CRTU hardware.Consult the installation procedures in the Installation Handbook 225, Section 880 to install the CRTU hardware.Part of the CRTU installation is to assign the CRTUm a directory number and to program the CRTUm with the cell-site-specific CDMA carrier assignment (1.23-MHz segment of spectrum). A CDMA carrier is specified by center RF channel number.The installer uses a special Lucent Technologies personal computer (PC) window-based tool to load the CRTUm directory number, the CDMA channel information, and many other mobile-related parameters into the CRTUm. The loading process is known as NAMing. (NAM stands for number assignment module.)3. Access the RC/V Series II Cell Equipage Common form (ceqcom2) and set the CDMA RTU - Status field to g for grow.

Functional tests can be initiated manually (on demand) to test new installations or troubleshoot suspected problems, or can be initiated on a scheduled basis (routine functional tests). The frequency, or interval value, of routine functional tests is specified in the ECP translations. The RCC automatically runs routine functional tests according to the prescribed schedule.* Complete this step only if you want to override the interval values specified in the ecp form (Step 7). The interval values on the ceqcom2 form for an individual cell take precedence over the ECP interval values.
Lucent Technologies — ProprietarySee notice on first page21-16 401-660-100 Issue 11 August 2000CDMA MaintenanceThe RCC uses the CRTU to perform CDMA functional tests on every antenna face (omni, alpha, beta, gamma, delta, epsilon, zeta) of a CDMA cell. The CRTU must be in the active state to perform the tests.There are two types of CDMA functional tests: overhead channel functional tests and traffic path functional tests. Testing is limited to one CDMA carrier per antenna face with the following exception: for CDMA Series II Cell Sites, CDMA traffic path testing of multiple CDMA carriers is supported.NOTE:Multiple CDMA carriers on an omni cell or cell sector consist of one or two common CDMA carriers and one or more optional non-common CDMA carriers. For the cellular band class (850 MHz), the TIA IS-95 standard defines two common carriers: the primary CDMA carrier, which is centered on RF channel 283 for System A (A band) and 384 for System B (B band), and the secondary CDMA carrier, which is centered on RF channel 691 for System A (A’ band) and 777 for System B (B’ band). Each CDMA omni cell or cell sector must be assigned at least one common carrier. Non-common CDMA carriers are chosen by the system operator within certain limits defined in the IS-95 standard. The 1.23-MHz bandwidth for a CDMA carrier suggests that the minimum center frequency separation between center frequencies is 1.23 MHz.NOTE:For the PCS band class (1900 MHz), candidates for common CDMA carriers range from channel numbers 25 to 1175 in increments of 25.NOTE:A common CDMA carrier has its own unique pilot channel, sync channel, paging channel, access channel, and traffic channels. A non-common CDMA carrier has its own unique pilot channel and traffic channels but no sync, paging, or access channels. In CDMA Release 3.0, there is one paging channel per common carrier per antenna face, known as the primary paging channel, which is covered (spread) using Walsh code function number 1.Each common CDMA carrier (primary, secondary) on an antenna face has one channel element (CE) configured as the pilot/sync/access overhead channel, known as the P/S/A CE, and another configured as the paging overhead channel, known as the page CE. The two CEs may be on the same CDMA channel unit (CCU) or on different CCUs within the same CDMA cluster.The overhead channel and traffic path functional tests verify the operation of the following Cell Site equipment: RF transmit paths, RF receive paths, and CDMA radio equipment.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-17CDMA Maintenance Default Interval Values The interval values for the routine (scheduled) CDMA functional tests are specified in the ECP translations. The default interval value for the routine overhead channel functional test is 25 minutes, and the default interval value for the routine traffic path functional test is 60 minutes.For a 3-sector cell, the various antenna faces are tested in a sequential fashion: sector 1 (alpha), then sector 2 (beta), and then sector 3 (gamma). Sector 1 is tested during the first 1/3 of the interval value, sector 2 is tested during the second 1/3 of the interval value, and sector 3 is tested during the last 1/3 of the interval value. A similar scenario holds true for a 6-sector cell.Transmit and Receive Test Paths Access to the transmit and receive test paths is established through the RCB, RSP, and the dual-port directional couplers located on the antenna side of the transmit and receive filter panels. The RCC selects the required test paths by controlling the switches on the RSP via an EIA-422 data link between the CRTUi and the RSP.The RCC directs the RSP to select the incident directional-coupler port of the transmit filter panel. This port passes a portion of the RF transmit signal from the CE_under_test to the CRTUm receiver.The RCC also directs the RSP to select the incident directional-coupler port of the receive filter panel associated with the diversity 0 receive path (See Figure 21-3). This port passes the RF transmit signal from the CRTUm to the CE_under_test.
Lucent Technologies — ProprietarySee notice on first page21-18 401-660-100 Issue 11 August 2000CDMA MaintenanceNOTE:Currently, the CDMA functional tests verify the operation of the diversity 0 receive path but not the diversity 1 receive path. Figure 21-3. RF Diversity 0 Receive Path Setup for CDMA Functional Tests atthe Series II Cell SiteMOST-Terminated Test Calls The CDMA functional tests require that the CRTU set up test calls using the mobile station test (MOST) feature.There are two types of CDMA MOST calls: those that are originated by the CRTU as described in this section, and those that are originated by any other IS-95 compliant test mobile. Both the ECP and RCC can distinguish between the two types of MOST calls because each type has a unique Mobile Directory Number Type value designated via the RC/V sub form. The Mobile Directory Number Type value for the CRTU is y.J2 P1 J1J20 J50 J60J40J30J10J3J4RSP1:4RCCP/O RCB*RF SWASSYCRTUi4442ACNTRL2P/O RCB*AYD8CNTRL2BC* RSP CONTROL BOARDCRTUmRXTXEIA-422 ASYNC INTErfACEA B CRX ANTDIV 01:6RX FILTER PANEL DIV 0WITHAYD 1 2P/O AIF0P/O RCF1 OR RCF2 (CDMA GROWTH FRAME)CDMARADIO SETP/O RCF0TDM BUSP/O FIFBBACDMACLUSTERCEsDFI(RF) (RF)
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-19CDMA MaintenanceThe RCC instructs the CRTU to dial the CRTU-designated MOST directory number. Upon receiving the call, the ECP identifies the call as a MOST call during digit analysis and terminates the test call to a low-tone source at the DCS. The ECP also identifies the call as a MOST call originating from the CRTU.NOTE:Both the ECP and RCC set certain bits in their call records to identify the call as a MOST call originating from the CRTU.By instructing the CRTU to send a certain 3-digit feature code, the RCC can trigger any one of several MOST test functions including forced handoff. During the traffic path functional test, the RCC uses the MOST forced handoff function to hand off the call from one traffic CE to another within the same physical antenna face, or sector, until the call has been handled by each idle (in-service and non-busy) traffic CE available to the antenna face.For a CDMA subcell * on an antenna face, the RCC uses the MOST forced handoff function to hand off the call to each idle CE in the subcell. For multiple subcells on an antenna face, the RCC uses the MOST forced handoff function to hand off the call to each idle CE in the one subcell, then hand off the call to each idle CE in the next subcell, and so on until the call has been handled by each idle CE available to the antenna face.Special software at the RCC provides the CE selection algorithm for the MOST forced handoff function. After the RCC triggers a MOST forced handoff, the CE selection algorithm starts at the CE currently handling the call and searches forward through an ordered list of CEs until it finds an idle CE to handle the call. The RCC then hands off the call to the selected CE. After executing the handoff, the RCC can either trigger another forced handoff to continue the test session or release the MOST call if all idle traffic CEs have been tested.Overhead Channel Functional Test The overhead channel functional test verifies the pilot, sync, paging, and access special purpose channels for each antenna face, or sector, of the cell. The testing of one antenna face takes approximately 30 seconds to complete.During overhead channel functional testing, the CRTU acquires the pilot, sync, and paging channels—known as the CDMA forward control channels—by locking on to a particular CDMA center frequency (carrier) and pilot pseudo-noise (PN) offset. During the final portion of the testing, the CRTU calls the CRTU-designated MOST directory number to verify access and paging operation.* At a CDMA cell, up to three CDMA shelves—shelves 0, 1, and 2 or shelves 3, 4, and 5—can be interconnected to form a subcell. All CEs within a subcell are available to the antenna face.
Lucent Technologies — ProprietarySee notice on first page21-20 401-660-100 Issue 11 August 2000CDMA MaintenanceThe overhead channel functional test may be initiated in one of three ways: by a manual request, by a timer—scheduled—assuming that the overhead channel functional tests are in the allowed state, or by the RCC after an overhead channel has been migrated to a different CE.NOTE:If during normal operations the RCC detects a failure in an overhead channel or a failure in the CCU carrying the overhead channel, the RCC will automatically migrate the overhead channel to another CE—select an idle traffic channel and reconfigure it as the overhead channel. The overhead channel CEs for a common CDMA carrier on an omni cell or cell sector must be on the same CDMA cluster, that is, must be controlled by the same CDMA cluster controller (CCC). This recovery action does not apply to a failure detected during CDMA overhead channel functional testing; with CDMA Release 3.0, the RCC takes no recovery action for a failed CDMA overhead channel functional test other than reporting the failure to the ECP.The overhead channel functional test consists of two parts:1. Pilot, sync, and paging channel acquisition test—Verifies that the overhead-channel forward path is functioning.The pilot channel is an unmodulated, direct-sequence spread-spectrum signal transmitted continuously by each sector of a CDMA cell. It allows the mobile to acquire the timing of the forward control channels and provides a coherent carrier phase reference for demodulating the sync and paging channels.The sync channel provides time-of-day and frame synchronization to the mobile. The mobile uses this channel to acquire cell and sector-specific information.The paging channel transmits control information to idle mobiles during mobile powerup and when a mobile is acquiring a new Cell Site. It conveys pages to the mobiles.For the pilot, sync, and paging channel acquisition test, the RCC instructs the CRTU to connect to a certain antenna face through the RSP. When connected to the antenna face, the CRTU acquires the pilot, sync, and paging channels for the face and transitions to the system idle state. The RCC then queries the status of the CRTU, to which the CRTU must return the system idle state for the test to pass.2. Access-paging channel test—Verifies that the overhead-channel reverse path is functioning.The access channel is a CDMA reverse channel used for short signaling message exchange such as mobile registration, mobile call origination, and response to pages. The access channel is a slotted random access channel used by mobiles to communicate to the Cell Site.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-21CDMA MaintenanceFor the access-paging channel test, the RCC instructs the CRTU to initiate a CRTU-designated MOST call. The test passes if the network can set up the call.For a multiple-sector cell, the RCC performs both parts of the overhead channel functional test on sector 1 (alpha), then performs both parts of the overhead channel functional test on sector 2 (beta), and so on until the RCC has tested all sectors of the cell.The overhead channel functional test consists of the following basic steps.1. The RCC selects an antenna face to test.2. The RCC instructs the CRTU to connect the RSP to the selected antenna face. (The CRTU connects the RSP to the transmit path and the diversity 0 receive path.)3. The RCC queries the status of the CRTU.4. The CRTU returns the system idle state to the RCC, indicating that the CRTU has acquired the pilot, sync, and paging channels.The RCC now knows that the overhead-channel forward path is functioning. What remains is to test the overhead-channel reverse path—perform the access-paging channel test.5. The RCC instructs the CRTU to dial the CRTU-designated MOST directory number.6. The CRTUm dials the MOST directory number.7. The P/S/A CE for the selected antenna face receives an “over the air” origination message from the CRTU and passes the message to its controlling CCC.8. The controlling CCC instructs its page CE to acknowledge the CRTU origination. The page CE sends an “over the air” acknowledgment message to the CRTU.9. The controlling CCC informs the RCC that the CRTUm has originated a call.10. The RCC instructs the CRTU to release the MOST call. The CRTU releases the call and then releases control of the RSP (and RCB for a Series II Cell Site).At this point, the overhead channel functional test for the selected antenna face is complete.NOTE:If the overhead channel functional test fails for any reason, the RCC will try up to two more times to complete the test. If all three attempts fail, the RCC
Lucent Technologies — ProprietarySee notice on first page21-22 401-660-100 Issue 11 August 2000CDMA Maintenancewill abort the overhead channel functional test for the selected antenna face.If the cell being tested has more than one antenna face, and if the test was initiated manually for more than one antenna face, the RCC will immediately select and begin testing the next antenna face. If the test was initiated by a timer—a scheduled functional test, the RCC will wait a certain amount of time before testing the next antenna face.The RCC will report the test results (pass, fail) of all manually initiated overhead channel functional tests to the ECP. In contrast, the RCC will only report the tests results of a routine (scheduled) overhead channel functional test if the test fails.Traffic Path Functional TestThe objective of the traffic path functional test is to verify that a CDMA traffic path can be established and maintained through every traffic CE on every antenna face, or sector, of the cell. A CE configured as a traffic channel contains the necessary circuitry to process one CDMA traffic channel.NOTE:A traffic channel, which is a communication path between a mobile station and a Cell Site, carries user and signaling information. The term traffic channel implies a forward and reverse pair.The test begins with an overhead channel functional test, during which the RCC instructs the CRTU to dial the CRTU-designated MOST directory number to test the access-paging portion of the overhead channel test. The RCC then completes the call using a traffic CE available to the antenna face being tested, and then hands off the call from CE to CE to test every traffic channel path available to the antenna face.The RCC repeats the MOST call origination and handoff for each antenna face of the cell. The testing time of one antenna face varies from less than one minute to more than three or four minutes, depending upon how many idle traffic CEs are available to the antenna face.The traffic path functional test may be initiated in one of two ways: by a manual request or by a timer—scheduled—assuming that the traffic path functional tests are in the allowed state.The traffic path functional test consists of the following basic steps.1. The RCC selects an antenna face and then performs an overhead channel functional test on that face. The RCC instructs the CRTU to dial the CRTU-designated MOST directory number to test the access-paging portion of
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-23CDMA Maintenancethe overhead channel test.Only if the overhead channel test passes will the RCC continue to Step 2.2. Upon receiving the CRTU origination, the RCC allocates a traffic CE to handle the call and sends a message to the ECP requesting message and subscriber validation. (RCC-ECP message exchange is through the Cell Site data link.)3. The ECP identifies the call as a CRTU-designated MOST call during digit analysis and terminates the test call to a low-tone source at the DCS.4. The ECP sends a subscriber validation message to the RCC. The ECP also sets up the proper speech handler connections at the DCS.5. The RCC passes the Walsh code assignment of the allocated traffic CE to the CCC controlling the page CE. The CCC instructs its page CE to send the assignment to the CRTU, and the page CE responds by sending an “over the air” channel assignment message to the CRTU.6. The RCC receives a speech handler assignment and a call ID from the ECP and passes the information to the CCC controlling the allocated traffic CE. (This CCC need not be the same CCC controlling the page CE.) The RCC also sends a channel confirmation message to the ECP.7. The CCC controlling the allocated traffic CE passes the speech-handler assignment and call ID to the traffic CE. The traffic CE uses this information to complete the call path through the DCS, at which time the MOST low tone is received by the CRTU.At this point, both the ECP and RCC have certain bits set in their call records to identify the call as a MOST call originating from the CRTU.8. The RCC queries the status of the CRTU. The CRTU returns the traffic channel state to the RCC, verifying that the CRTU is in the talk state.9. The RCC instructs the CRTU to send a certain 3-digit feature code to trigger the MOST forced handoff function. The CRTU sends the 3-digit feature code as an “over the air” flash with information message, which is extracted by the traffic CE and forwarded to the RCC.(CDMA supports both mobile-to-ECP and ECP-to-mobile flash with information messages. The communication path consists of (1) the mobile-to-RCC path via the established traffic channel and (2) the RCC-to-ECP path via the Cell Site data link. The flash with information messages are used to support certain feature activations and deactivations such as MOST service requests, 3-way calling, and call waiting. The contents of a flash with information message sent to the mobile will display on the mobile’s backlit display.)
Lucent Technologies — ProprietarySee notice on first page21-24 401-660-100 Issue 11 August 2000CDMA Maintenance10. The RCC sends the flash with information message to the ECP. (RCC-ECP message exchange is through the Cell Site data link.) The ECP sends a MOST forced handoff command to the RCC.11. The MOST CE selection algorithm at the RCC selects the next CE to which the call should be handed off. The RCC writes data pertaining to the selected CE (CE, CCU, CCC, and sector) into a global data area and then attempts to hand off the MOST call to the selected CE.12. If the handoff is successful, the RCC reports the result to the ECP and sends an “over the air” flash with information message to the CRTU. The message contains the CE, CCU, CCC, and sector pertaining to the handed-off call. (Since the mobile is inside the CRTUm, you will not be able to see the message on the mobile’s backlit display.) The RCC also updates the global data area for the selected CE with the successful test result.If the handoff fails, the RCC reports the result to the ECP but does not send an “over the air” flash with information message to the CRTU. The RCC updates the global data area for the selected CE with the failed test result.13. After executing a forced handoff, the RCC consults the global data area to determine whether to trigger another forced handoff or terminate the test session. The RCC will terminate the test session if all idle traffic CEs available to the selected antenna face have been tested.14. To terminate the traffic path functional test, the RCC instructs the CRTU to release the MOST call. The CRTU releases the call and then releases control of the RSP (and RCB for a Series II Cell Site).At this point, the traffic path functional test for the selected antenna face is complete.If during the test a handoff fails and the call drops, the RCC will try up to three times to re-establish the call. If successful, the traffic path functional test will continue with a handoff to the next CE after the last failed CE. If all three attempts fail to re-establish the call, the RCC will abort the traffic path functional test for the selected antenna face.If the cell being tested has more than one antenna face, and if the test was initiated manually for more than one antenna face, the RCC will immediately select and begin testing the next antenna face. If the test was initiated by a timer—a scheduled functional test, the RCC will wait a certain amount of time before testing the next antenna face.The RCC will report the test results (pass, fail) of all manually initiated traffic path functional tests to the ECP. In contrast, the RCC will only report the tests results of a routine (scheduled) traffic path functional test if the test fails.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-25CDMA MaintenanceFunctional Test Errors and System Recovery ActionsWhen a CDMA functional test fails, the RCC hardware error handler (HEH) software subsystem responds in one of two ways, depending upon the failure:■Reports the failure to the ECP, takes action to correct the failure, and then reports the result of the recovery action to the ECP.■Does nothing more than report the failure to the ECP.The ECP decodes the data in the HEH-initiated report into an output message and prints the output message at the read-only printer (ROP). In situations where no automatic recovery action is taken or automatic recovery action fails, the technician must perform manual recovery procedures from the ECP. Manual recovery procedures for a failed overhead channel or traffic path functional test can be found in the Release 3.0 Isolation Strategy memorandum written by Thomas E. Wing.When a technician initiates a CDMA functional test, the RCC will report the test results (pass, fail) to the ECP. In contrast, the RCC will only report the tests results of a routine (scheduled) CDMA functional test if the test fails. The RCC routine maintenance scheduler (RMS) software subsystem generates the report (pass, fail) for manually initiated CDMA functional tests, whereas HEH generates the report (fail only) for routine CDMA functional tests.General Errors Some errors are common to both the overhead channel and traffic path functional tests. Those errors, together with the automatic recovery actions, are listed and described below:■Functional test timer expired.The RCC sets a timer at the beginning of a functional test; if the functional test does not complete before the timer expires, the functional test aborts. HEH takes no recovery action other than to report the failure to the ECP.■RCC-to-CRTUi communication failureHEH conditionally restores the CRTU and sends a report to the ECP.■CRTUi-to-CRTUm communication failureHEH conditionally restores the CRTU and sends a report to the ECP.Overhead Channel Functional Test Errors Currently, for a failed overhead channel functional test, HEH does nothing more than report the failure to the ECP. The technician must perform manual recovery procedures from the ECP.What follows is an RMS-generated report for a manually initiated overhead channel functional test that passed:M 40 EXC:CELL 132 FT OC, COMPLETED       OC 1            COMPLETED    ALL TESTS PASSED

If a sector fails the overhead channel functional test, the RMS-generated report identifies the failed sector but does not identify the location of the faulty overhead channel CE. RMS makes no attempt to identify the faulty CE.Compare the previous RMS-generated reports with the following HEH-generated report:M 23 REPT:CELL 132 HEH, CCC 7, CCU 2, CE 0     PID: OS= FTSUPV, N/A, 0     FT OC FAILURE: NO_OVERHEAD     99 15 00 00 84 00 02 a8 00 00     00 00 00 10 07 75 00 02 03 23     00 00 5b 19 04 52An HEH-generated report differs from the RMS-generated report in that (1) the HEH-generated report does not include sector numbers, (2) the HEH-generated report does not include any information about individual tests that passed, and (3) the HEH-generated report does include the location of the faulty overhead channel CE. HEH identifies the faulty CE by CE number, CCU number, and CCC number.Traffic Path Functional Test ErrorsA traffic path functional test will fail for any one of the following reasons:■Executing the overhead channel test portion of the traffic path functional test revealed that one or more overhead channels are not working. The test aborts. The reason identified here will appear in the report sent to the ECP.■MOST call was unexpectedly torn down. The test aborts. The reason and source of the call termination will appear in the report sent to the ECP.■Handoff to selected CE failed and the call dropped. The test continues assuming a call can be re-established within three attempts; otherwise, the test aborts. The failed CE will appear in the report sent to the ECP.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 21-27CDMA Maintenance■Handoff to selected CE is rejected but the call is maintained on the previously selected CE. The test continues; the CE selection algorithm selects the next CE for testing. The failed CE will appear in the report sent to the ECP. Currently, for any type of failure encountered during a traffic path functional test, HEH takes no recovery action other than to report the failure to the ECP. The technician must perform manual recovery procedures from the ECP.What follows is a RMS-generated report of a manually initiated traffic path functional test that passed:M 49 EXC:CELL 132 FT TP, COMPLETEDTP 1  COMPLETED  ALL TESTS PASSEDCCC  7, CCU 2, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 4, CE  0  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 4, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 5, CE  0  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 5, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 6, CE  0  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 6, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 1, CE  1  COMPLETED     ALL TESTS PASSEDWhat follows is a RMS-generated report of a manually initiated traffic path functional test that failed:M 06 EXC:CELL 132 FT TP, COMPLETEDTP 1  PARTIALLY COMPLETED LOST TRAFFICCCC  7, CCU 4, CE  0  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 4, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 5, CE  0  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 5, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 6, CE  0  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 6, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 1, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 2, CE  1  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 3, CE  0  COMPLETED     ALL TESTS PASSEDCCC  7, CCU 3, CE  1  PARTIALLY COMPLETED LOST TRAFFICAn RMS-generated report contains the results for each sector tested (TP 0 = omni, TP 1 = sector 1, TP 2 = sector 2, ...) and the results for each traffic CE tested within the individual sectors.

Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 22-3Linear Amplifier Circuit (LAC) MaintenanceLAC Maintenance Procedures This chapter provides the recommended procedures for identifying and troubleshooting problems with Linear Amplifier Circuits (LACs) in Series II cell site. All cell site maintenance personnel and ECP operators should be familiar with these procedures. It is important to recognize that there are a number of preliminary diagnostic steps which should be taken at the MSC, prior to dispatching maintenance personnel to the cell site. Lighted LAC LEDs at the cell site or LAC alarm reports at the MSC, by themselves, do not provide sufficient information for troubleshooting LAC problems. LAC maintenance procedures should include the following four steps: 1. Obtaining and analyzing LAC alarm reports at the MSC. These include both the "LACSUM" and "LACALM" reports. 2. Assigning priorities to LAC alarms and, if necessary, dispatching maintenance personnel to the cell site. 3. Observing visual indicators at the cell site and determining the proper course of action indicated in the table. 4. Performing the procedures indicated in the table to determine the cause of the problem and then taking the proper steps to remedy the situation. The response to LAC alarms should be prioritized depending upon the type of alarm being generated, either MINOR, MAJOR, or CRITICAL. The appropriate response also depends upon whether the alarm is continuous or intermittent. Continuous alarms, which are more likely to be service affecting, are also relatively easy to detect at the MSC and to troubleshoot at the site. Intermittent alarms, while often harder to diagnose than continuous alarms, are generally not service affecting. Knowledge of LAC alarm history is extremely useful for determining the cause of LAC-related problems. While at the cell site, maintenance personnel should also be in constant contact with the operator at the MSC in order to monitor the current LAC alarm status. The LAC Alarm Query System (LAQS) test equipment can also be used to monitor the LAC alarm status at the site. Although reported as LAC alarms, many problems may be caused by other equipment in the cell site, such as failed radios, loose or faulty cabling, failed alarm reporting circuits in the Radio Channel Frame (RCF), etc. While every effort has been made to consider these potential causes in the procedures described herein, problems will occasionally arise which have not been considered. For further assistance, call the CTSO Hotline at 1-800-225-4672.

This report provides a summary of the day's LAC alarms for each cell site controlled by the ECP. After logging on, type in the following commands: NOTE:As an aid in troubleshooting, a copy of the LACSUM report should be taken to the cell site when performing maintenance. The LACSUM report, which is updated hourly, records the number of LAC alarms, by category, for up to 24 hours beginning at 6AM. At 6AM the following day, the 24 hour summary is saved for reference as LACSUM.Ext, where Ext denotes the day of the week the file was saved. (LACSUM.Fri contains alarms from 6AM Thursday to 6AM Friday.) A sample LACSUM report listing alarm totals by cell and LAC number under the following categories is shown in Table 22-1: * If the LACSUM file is not found in the LACMON directory on the ECP, contact the system administrator or call the AT&T CTSO Hotline at 1-800-225-4672. cd /user/pecc/LAC-MON to change to the LACMON directory cat LACSUM to list the LACSUM file

Note that the LACs in cells 1 and 13 are issuing an alarm every hour, indicating a continuous alarm. All other alarms are intermittent. Also, the LAC in cell 106 is issuing a combination of MINOR and MAJOR alarms, which may indicate multiple Linear Amplifier Modules (LAMs) in alarm. This is in contrast to the LAC in cell 9, which is only issuing MAJOR alarms, indicating a Preamp problem. An easy way to view alarm activity throughout the day for a particular LAC is to search the file for each occurrence of a particular string of characters by using the grep command. For example, to see all alarms for cell 1, LAC 3, beginning at 6 AM, enter: grep '1 3' LACALM (Press the TAB key between 1 and 3) The computer will return the following from the example LACALM file: 9 1 **A  05/05/93 16:04 9 1 **A  05/05/93 16:13 1 3 **S  05/05/93 16:21 13 2  A  05/05/93 16:21 9 1 **A  05/05/93 16:22 6  2  * A  05/05/93 16:24 6  2  * A  05/05/93 16:44 1 3 **S  05/05/93 17:21 13 2  A  05/05/93 17:21 106  5  * A  05/05/93 17:51 106  5  * A  05/05/93 17:54 106 5  **A  05/05/93 17:57 1 3 **S  05/05/93 18:22 13 2  A  05/05/93 18:22 18 0  **S  05/05/93 18:33 18 1  **S  05/05/93 18:33 18 2  **S  05/05/93 18:33 1 3 **S  05/05/93 19:21 13 2  A  05/05/93 19:21 12 0  *CA  05/05/93 19:55

Interpreting the LAC Alarm Reports This section describes how to interpret the LACSUM and LACALM reports at the MSC. The following alarm descriptions are intended as a guide for determining possible causes and corrective actions for LAC alarms, to the greatest extent possible, from the MSC. Knowledge of the detailed troubleshooting procedures in paragraph D is assumed. It is also important to understand the differences in how A/B-Series and C-Series LACs report alarms, as described in paragraph F. Additional technical details of the LAC alarm detection and reporting system are also included in paragraph G. NOTE:Be sure that the line of "equals" signs is printed out at the bottom of the LACSUM report. This line indicates that the hourly update has been completed. If this line is not present, the file was printed in the middle of the update and is not complete. Reprint the file.  1 3 **S 05/05/93 06:21 1 3 **S 05/05/93 07:22 1 3 **S 05/05/93 08:21 1 3 **S 05/05/93 09:21 1 3 **S 05/05/93 10:22 1 3 **S 05/05/93 11:21 1 3 **S 05/05/93 12:21 1 3 **S 05/05/93 13:21 1 3 **S 05/05/93 14:22 1 3 **S 05/05/93 15:21 1 3 **S 05/05/93 16:21 1 3 **S 05/05/93 17:21 1 3 **S 05/05/93 18:22 1 3 **S 05/05/93 19:21
Lucent Technologies — ProprietarySee notice on first page22-8 401-660-100 Issue 11 August 2000Linear Amplifier Circuit (LAC) Maintenance!CAUTION:Be careful that LAC alarms generated as a result of recent maintenance activities are not mistakenly interpreted as legitimate LAC alarms. This can be avoided by printing out the LACSUM file, not LACSUM.Ext, at the beginning of the maintenance window. Continuous Alarms Continuous alarms are potentially service affecting and should be attended to promptly. Since continuous alarms are reported once an hour, the number of occurrences recorded will depend upon the time period covered by the LACSUM report. A full 24-hour summary report would show 24 occurrences for a continuous alarm. In the example above, cell 1, LAC 3 lists 14 occurrences over a 14-hour period, which may indicate a continuous alarm. Suspected continuous alarms should be confirmed by looking at the detailed LACALM report, as illustrated in the preceding example. MINOR Alarms The table summarizes the possible causes of MINOR alarms. These causes are, in order of likelihood: LAM alarms, Processor alarms, and Low-Level Thermal alarms. Intermittent MINOR alarms are generally not service affecting, but may lead to a service-affecting condition if they persist. A small number of intermittent MINOR alarms (less than 5 per day) is not usually cause for concern since they can be expected to occur, occasionally, as a result of transient traffic conditions. If they continue to occur over a number of days, or increase in frequency over time, a site visit may be warranted. NOTE:A/B-Series LACs report fan failures and LAM bias power failures as MINOR alarms. Beginning with the 1C LAC, these conditions are reported as MAJOR and CRITICAL alarms, respectively. See the Fan Alarm Procedure and LAM Bias Fault Procedure for further details. LAM alarms are the most frequent cause of MINOR alarms and are commonly caused by a bad LAM or its associated fuse. Large numbers of intermittent MINOR alarms are usually due to a faulty LAM or a loose LAM fuse, whereas a continuous MINOR alarm is usually due to a blown LAM fuse. A bad LAM or fuse is indicated at the cell site by a lighted LAM LED on the circular power distribution (AYM) board. If no LAM LEDs are visible upon entering the site, use the Radio Control Procedure to uncover suspected LAM alarms. Processor alarms are less frequent and are indicated at the cell site by a lighted LINEARIZER LED on the LAC. If the Radio Control Procedure fails to identify a bad LAM, the Processor Alarm Query Procedure should be performed to
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 22-9Linear Amplifier Circuit (LAC) Maintenancedetermine if the LAC has issued a Processor alarm. A LAC should not be replaced for a MINOR alarm if it has not issued a processor alarm*. Low-level Thermal alarms indicate that the LAC is beginning to overheat. Overheating may be caused by the LAC being overdriven or may be due to a Linear Amplifier Unit (LAU) fan failure or a cell site air conditioning failure. This type of alarm is seldom encountered. See Thermal Alarm Procedure. NOTE:If the LAC has not issued a processor alarm and over-heating has been ruled out, an intermittent MINOR alarm was most likely caused by an LAM. It is often difficult to identify LAMs which alarm only a few times in one day. Since a failed LAM is not service affecting, it may be best to continue to monitor the LAC from the MSC and return to the site if the alarms become more frequent. MAJOR Alarms  MAJOR alarms are, in order of likelihood: ■Preamp alarms■Multiple LAMs in alarm■a blown Final Correction Amplifier (FCA) fuse■a failed fan (C-Series LACs)■a mid-level thermal alarm. A major alarm, particularly a continuous alarm, indicates that the LAC is operating in a condition which may be service affecting, or may soon become so. Although the LAC output power may be reduced (due to a bad preamp or a blown preamp fuse), service should not be completely interrupted due to a MAJOR alarm condition. * Except for A/B-Series LACs with a LAM Bias Fault. See LAM Bias Fault Procedure.

Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 22-11Linear Amplifier Circuit (LAC) MaintenancePreamp alarms are the most frequent cause of MAJOR alarms. MAJOR alarms without accompanying MINOR alarms are almost always generated by the Preamp, especially if they are intermittent. A bad Preamp or blown Preamp fuse is indicated by a lighted LAC Preamp LED at the cell site. If a Preamp LED is not visible upon entering the cell site, use the Radio Control Procedure to uncover an intermittent preamp problem. See Preamp Alarm Procedure. Multiple LAMs in alarm will also generate MAJOR alarms. This may involve from 2-6 LAMs, depending upon the LAC configuration. A tripped LAC breaker will cause groups of LAMs to generate a continuous MAJOR alarm. Intermittent MAJOR alarms of this type are usually accompanied by MINOR alarms, since individual failed LAMs may not respond exactly the same to changing traffic conditions. This type of LAM alarm is usually easy to diagnose at the cell site since multiple LAM LEDs will be lighted. See LAM Alarm Procedures. A blown FCA fuse will generate a MAJOR alarm in C-Series LACs. This may be caused by the LAC being over-driven or may result from the LAC being powered-up with too many radios turned on. A blown FCA fuse is indicated by a continuously lighted LINEARIZER LED at the cell site. (A/B-Series LACs report a blown FCA fuse as a MINOR alarm. The FCA fuse is not field accessible in these LACs, however.) A bad fan or a blown fan fuse will also generate a MAJOR alarm in C-Series LACs, which is indicated at the cell site by a lighted FANS LED in combination with another lighted LED indicating the particular fan, either LINEAR AMPLIFIER UNIT, PRE-AMPLIFIER, or LINEARIZER. See FAN Alarm Procedure. Mid-level Thermal alarms indicate that the LAC is about to overheat. Overheating may be caused by the LAC being overdriven or may be due to an LAU fan failure. These alarms will be preceded in time by low-level thermal alarms (MINOR) and should usually not be allowed to progress to the mid-level. (A cell site air conditioning failure should not cause the LAC to heat up to the mid-level, as long as the LAU fan is functioning properly.) See Thermal Alarm Procedure. CRITICAL Alarms CRITICAL alarms are, in order of likelihood: ■Multiple LAMs in alarm■A complete loss of LAM Bias Voltage■A failed component in the Linearizer ■A High-level thermal alarm. !CAUTION:A CRITICAL LAC alarm results in immediate loss of service and must be attended to promptly. (When a critical alarm condition is detected, bias
Lucent Technologies — ProprietarySee notice on first page22-12 401-660-100 Issue 11 August 2000Linear Amplifier Circuit (LAC) Maintenancevoltage is removed from the LAMs, thereby shutting down the RF output power of the LAC.) Multiple LAMs in alarm due to tripped breakers are the most common cause of CRITICAL alarms. Other possibilities include multiple blown LAM fuses or failed LAMs, although it is unlikely that the number of LAM failures would have been allowed to progress to this level. This type of failure is indicated by multiple lighted LAM LEDs at the cell site. See LAM Alarm Procedures. NOTE:When a CRITICAL number of LAM failures has been detected, 5-volt LAM bias is turned off, shutting down the LAMs, and a CRITICAL alarm is issued. The radios on the LAC will be blocked from service by the ECP in response to the CRITICAL alarm. Once the LAMs shut down, or RF is removed, LAM failures can no longer be detected (except for a blown fuse) and the CRITICAL alarm will clear after about a 5-second delay. If radios are re-applied before the cause of the CRITICAL alarm condition is corrected, the cycle will repeat. An LAM bias fault will also generate a CRITICAL alarm on C-Series LACs and is indicated by simultaneously lighted LINEAR AMPLIFIER UNIT and LINEARIZER LEDs (See Figure 22-11) at the cell site. See LAM Bias Fault Procedure. High-level thermal alarms indicate that the LAC has overheated. The LAC will shut itself down when its temperature reaches this level and will remain shut off until its temperature falls to the mid-level. Overheating may be caused by the LAC being overdriven or may be due to an LAU fan failure. This alarm will be preceded in time by low-level (MINOR) and mid-level (MAJOR) thermal alarms and should not be allowed to progress to the high level. (A cell site air conditioning failure should not cause the LAC to heat up to the high-level, as long as the LAU fan is functioning properly.) See Thermal Alarm Procedure. SANITY Alarms SANITY (MAJS) alarms indicate that the LAC is not responding correctly to queries by the UN166 Alarm/FITS Interface (AFI) Board in the Radio Channel Frame. Common causes include mis-addressed LACs, faulty alarm cables, and incorrectly installed LAC microprocessors. SANITY alarms may also be caused by a damaged alarm circuit in a LAC or in a UN166/AFI board. In the presence of LAC SANITY alarms in a cell, view all LAC alarms with suspicion. One mis-addressed or otherwise "insane" LAC will often confuse alarm reporting for all LACs in the site. Cell 18 (paragraph B) illustrates a situation where 3 LACs are reporting SANITY alarms, as well as other alarms. This is most likely the result of a problem with only one of the LACs.
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 22-13Linear Amplifier Circuit (LAC) MaintenanceSANITY alarms, by themselves, are not service affecting, but they may mask other service-affecting conditions. Therefore, this type of alarm should be investigated promptly. NOTE: Resolve SANITY alarms before attempting to troubleshoot other alarms, since the other alarms may or may not be real. See Sanity Alarm Procedure. INFO Alarms All alarms which do not fit into one of the four previous categories are reported as INFO alarms. The only alarms which fall into this category are Input Drive alarms, which are issued by the LAC when it is being overdriven. This type of alarm should be investigated promptly, since overdriven LACs can trip breakers, resulting in a CRITICAL alarm condition. NOTE:An INFO alarm will often be issued as a result of problems with the alarm reporting system and may occur in combination with SANITY alarms. A damaged UN166 AFI Board will often issue Input Drive warnings when they don't really exist. See Info Alarm Procedure. Troubleshooting Procedures at the Cell Site Initial Procedure at the Cell Site LAC alarm indicator LEDs may not be lit when initially entering the cell site. Many alarms are dependent on radio traffic and may be intermittent, making them difficult to diagnose. This is especially true of LAM alarms (MINOR), as well as Preamp alarms (MAJOR). Check the LACALM file to determine the time of day when alarms occur most often and visit the site at that time, if possible. Upon entering the cell site: 1. Observe the LAM LEDs and the LEDs on the front faceplate of the LAC. 2. If LEDs are ON, follow the procedure indicated in the LAC Alarm Troubleshooting table. 3. If NO LEDS are ON, —and MINOR or MAJOR alarms have been reported, follow the Radio Control Procedure below. —and SANITY alarms have been reported, proceed to Sanity Alarm Procedure. —and INFO alarms have been reported, proceed to INFO Alarm Procedure.
Lucent Technologies — ProprietarySee notice on first page22-14 401-660-100 Issue 11 August 2000Linear Amplifier Circuit (LAC) MaintenanceRadio Control Procedure for Traffic Dependent Alarms This procedure is used to exercise the LAC in order to uncover those types of alarms which are traffic dependent. The conditions under which an alarm is generated often depends upon the number of radios active, the frequencies at which they are operating, and also upon the operating temperature of the LAC and/or Preamp. Observe the LAC LEDs while following the procedure described in Step 2 below. When an alarm and LED is observed, refer to the table for the appropriate troubleshooting procedure. If an LED does not light while performing Step 2, follow the instructions given in Steps 3 through 6. 1. Have the MSC take the radios on the LAC out of service. 2. Have the MSC configure (Turn ON) all radios* on the LAC. a. Wait 1 minute. Turn OFF one radio with the manual switch. b. Wait 3 seconds. Turn OFF another radio. c. Continue in this manner until all radios are off. d. Turn ON one radio. Watch for an LED for 3 seconds. Turn OFF the radio. e. Turn ON the next radio. Watch for an LED for 3 seconds. Turn OFF the radio. f. Continue in this fashion until each radio has been tried, one at a time. g. Turn ON all radios and observe the LEDs while allowing the LAC to warm up for 5 minutes. h. After the LAC has warmed up, repeat steps a through f, above. i. When finished, have the MSC reinstate the radios into service. 3. If a lighted LED is not observed, and major alarms have been reported, refer to the LACALM report to determine the time of day when the alarms occur, and return to the site at that time. 4. If a lighted LED is not observed, and minor alarms have been reported, check that all LAM fuses are securely seated in their sockets. If an LAM LED lights when its associated fuse is wiggled, remove the fuse and bend the leads slightly; looking at the bottom of the fuse with one lead on the left and one on the right, bend one slightly up, and the other slightly down. Reinsert the fuse. * For information on using the CFR MULTI command to turn on multiple radios, refer to AT&T 401-610-055 Issue 5, AUTOPLEX Cellular Telecommunications Systems Input Messages, Volume 1.

If a lighted LED is still not observed, and minor alarms have been reported, proceed to the Processor Alarm Procedure to determine if the LAC has generated a processor alarm. 6. If the LAC has not issued a Processor alarm, and minor alarms have been reported, the alarm was probably caused by a faulty LAM or a loose LAM fuse. Refer to the LACALM report to determine the time of day when the alarms occur, and return to the site at that time. !CAUTION:Make sure that all radio switches are turned ON before leaving the cell site. LAM Alarm Procedures  Case 1 - One or More Individual LAM LEDs Light Symptoms: Non-adjacent LAM LEDs are lighted. If a group of adjacent LAM LEDs are lighted, see Case 2 below. Probable Causes: 1. LAM fuse improperly seated in socket. 2. Blown or missing LAM fuse. 3. LAM module not properly seated in LAU. 4. Improperly seated LAM ribbon cable connector. 5. Faulty LAM module. NOTE:A faulty LAM requires at least one radio to be active with a LAC output power of at least 15 watts in order to issue an alarm and light its LED. If a LAM failure is suspected and no LAM LEDs light, follow the Radio Control Procedure to apply radios to the LAC. Procedure: 1. Check that the associated LAM fuse is securely seated in its socket. If the LED goes out when the fuse is wiggled, remove and bend the leads slightly: looking at the bottom of the fuse with one lead on the left and one on the right, bend one slightly up, and the other slightly down. Reinsert the fuse. Check all other LAM fuses. 2. Make sure that the LAM is securely seated in the LAU and that the thrumbscrew, which secures the LAM in the LAU, is tight. (Thumbscrews should be finger tight.) 3. Remove and reseat the LAM ribbon cable connector.

Remove and check the fuse; if the fuse is good proceed to Step 5. a. If the fuse is blown, replace it with a new fuse. Do not take one from a 10 LAM LAC, thinking the fuse is spare just because the slot is not equipped with an LAM. NOTE:A good fuse must always be in place to prevent a false alarm. b. If the fuse blows right away with little or no traffic present, replace the LAM. c. If within the maintenance window, have the MSC turn up (configure) all the radios on the LAC and wait 15 minutes to be sure the fuse doesn't blow again under full power conditions. If it does, move the LAM to another position. If the fuse blows in the new position, replace the LAM. d. If more than one LAM has a blown fuse, check the output power of the LAC to be sure it is not being overdriven. (See Step 3 for Case 2 below.) e. If the LAC is operating within its power rating, and an LAM continues to blow fuses, regardless of position, replace the LAM. 5. Interchange the suspect LAM with another LAM in the LAU. If the suspect LAM still alarms, replace it. Before concluding that the alarm has cleared, be sure that there is at least one radio active with a LAC output power of at least 15 watts. 6. Use the Radio Control Procedure to check with each radio ON alone, and then with all radios ON together. Case 2 - Groups of LAM LEDs Light Symptoms: 1. For a 20 LAM LAC: groups of 5 LEDs are lighted sequentially. 2. For a 10 LAM LAC: groups of 2 or 3 LEDs, depending on the breaker. Probable Causes: One or more tripped 20A breakers feeding the LAU. Procedure: 1. Check the main 20A breakers (See Figure 22-2).
Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 22-17Linear Amplifier Circuit (LAC) Maintenance—If only one breaker has tripped, and it is found during an active traffic period, reset the breaker, verifying that it does not trip again. If the breaker does trip again, have the MSC block one or more radios from service until the breaker holds. Return during the maintenance window. —If a tripped 20A breaker is found during the maintenance window, have the radios taken out of service. Turn off all breakers supplying the LAC, wait 10 seconds, then turn all breakers back on, beginning with the breaker supplying the Linearizer. 2. If breakers trip again without any radios on, check for shorts in the DC power cabling, frame capacitors, LAM power connectors, etc. 3. During the maintenance period, have the MSC configure all of the radios on the LAC. Using the switch on each radio, turn off all but one and measure the output power of each radio at the J4 antenna connector to be sure that the LAC is operating within its rating of 240 watts for a full-power LAC or 100 watts for a half-power LAC, taking into account the insertion loss from the LAC output to the J4 antenna connector. 4. Verify with the MSC that the radios on the LAC are using the correct VRAL settings. 5. In addition to measuring the output power at the J4 antenna connector, verify that the insertion loss between the LAC and the J4 antenna connector is correct by measuring the power on the output end of the first cable leaving the LAC. 6. If the LAC is operating close to its maximum power rating and a breaker trips with all radios ON, turn OFF one or two radios. If the breaker no longer trips, swap three of the LAMs operating from the tripping breaker with LAMs operating from the other breakers, one from each breaker. Check again with all radios ON. NOTE:When measuring RF power, always allow margin for measurement uncertainty; for example, assuming an uncertainty of 5%, be sure the power does not exceed 95% of rating. If it is high, readjust the power.Case 3 - All LAM LEDs Light Probable Causes: 1. Tripped breakers 2. 10/20 LAM switch setting Procedure:

Before a preamp is installed, check that the gain adjustment screw is turned fully counter-clockwise (minimum gain). 2. Before adjusting the gain, be sure to allow at least a 30-minute warm-up period to allow the preamp to stabilize. Notes about Preamp Alarms 1. A blown fuse can result in an intermittent alarm for some preamps; the alarm will clear without traffic. This is true for AT&T as well as Amplidyne preamps. Trontech and Decibel units will give a continuous alarm for a blown fuse. This is due to a difference in the implementation of the alarm circuitry. LAMLEDs10/20SWITCHLAMFUSES

The preamp alarm circuitry monitors the output power difference between the two redundant RF power paths within the preamp. Therefore, in the very unlikely case of two blown fuses, both outputs will be zero and an alarm will not be issued. 3. A preamp alarm may occur at low power level but not at high, or vice versa, or it may be a function of frequency and occur with one radio or group of radios but not with another. Use the Radio Control Procedure to check for intermittent preamp alarms. Preamp Troubleshooting Procedures Symptoms: 1. Major Alarms reported at the MSC. 2. The PREAMP LED on the LAC lights for some combination of radios. 3. The FANS LED is not lighted. Probable Causes: 1. Blown Preamp fuse. 2. Loose or faulty RF connections at the preamp input/output. 3. Faulty DC cable to the preamp. 4. Faulty preamp. Procedure: 1. Make certain that all RF cables are tight. 2. Follow the Flow Chart (See Figure 22-4).

Lucent Technologies — ProprietarySee notice on first page22-22 401-660-100 Issue 11 August 2000Linear Amplifier Circuit (LAC) Maintenanceappears as a MAJOR alarm on the ROP, with the word SANITY after the LAC number, and is listed on the LACSUM report under the heading, MAJS. Incorrect LAC address settings are a common cause of LAC SANITY alarms. Addressing problems are usually only encountered upon initial LAC installation or when a LAC is changed. LAC SANITY alarms may also be generated when alarm bus circuits on either the UN166 AFI board or on the LAC are damaged. NOTE:All LACs in a cell site are connected together on a common alarm bus, with each LAC on the bus assigned a unique identification or "address" number. Since the LACs share a common alarm bus, one faulty cable or alarm circuit, or mis- addressed LAC, can contaminate the bus, causing multiple SANITY alarms, or result in the reporting of false alarms. Setting LAC Addresses It is common practice to assign an address to correspond with the position of the LAC in the frame, with the first frame assigned addresses 0,1,2 and 3 and the growth frame assigned 4,5, and 6. Although not recommended, other numbering schemes are also used. If in doubt, check the cell site addresses in the CEQCOM2 database* on the ECP. Whenever an LAC is installed in a frame, its alarm address must be set (See Figure 22-5). The address† is set (in binary) from 0 to 31, using the 5 position rocker switch on the AYE1 board, which is accessed via a window in the front of the Linearizer. Be sure that no address is used more than once, since the data will be corrupted if more than one LAC attempts to "talk" on the bus at the same time. NOTE:In recently produced LACs the FAC/FLD switch (See Figure 22-10) was moved to the front of the Linearizer (See Figure 22-11) to allow easier access. LACs with this feature have a 6-position dip switch in place of the 5-position switch. The top switch, labeled "1", is used for the FAC/FLD setting and the bottom 5 switches, labeled 2-6, are used for the address setting. LACs with this feature are clearly marked. * See AT&T 401-610-036, AUTOPLEX Cellular Telecommunications Systems Data Base Update Guide, for further information. †Beginning with Series II Cell Site Software Release 4.3, only LAC addresses 0 - 6 are permitted.

Setting the LAC Address Sanity Alarm Troubleshooting Since all LACs in the cell site share a common alarm bus, finding the source of SANITY alarms can often be difficult, since a single faulty alarm interface in an LAC or in one of the two UN166 AFI boards can confuse the alarm reporting for all devices attached to the bus. Although the following procedure is most effective when SANITY alarms are continuous, the same steps should be followed to diagnose intermittent SANITY alarms. Current LAC alarm status may be determined at the cell site by using the LAC Alarm Query System (LAQS) test equipment described in paragraph E. Although it is possible to diagnose LAC SANITY problems without using this equipment, the LAQS system makes the job much easier. Using this equipment is simply a matter of disconnecting the LAF alarm cables from the RCF and then connecting the LAQS system to the LAF(s) or to an individual LAC. See paragraph E for further details. Symptoms: One or more LACs are reporting SANITY alarms at the MSC. Probable Causes: Incorrect LAC address settings, a damaged UN166 AFI board, a damaged LAC, an improperly installed LAC microprocessor, loose or damaged alarm bus cables or connectors. 0123456SW-1 SW-2Switch SettingsSW-3 SW-4 SW-5LACAddress012 43500000000000000011111111100000000000

Check that all five breakers on each LAC are ON. 2. Check all LAC addresses, verifying that each LAC has a unique address. Verify with the MSC that the number of LACs shown on the MCRT agrees with the number of LACs in the site. If in doubt about the LAC addressing scheme, check the CEQCOM2 database. 3. Check the alarm bus cabling between frames, making sure that all connectors are properly seated, from J104 on RCF0 to J2 on LAF0, and from J1 on LAF0 to J1 on LAF1.4. Make sure that the AYD5 Paddle Board is properly seated on the RCC backplane in the Radio Channel Frame.5. Remove the inactive UN166 AFI board from the Radio Channel Frame. a. Using an ohmmeter, measure the resistance between Pin 1 and Pin 8 on the 26LS32 chip on the AFI board. Likewise, measure the resistance between Pins 2 and 8. Both resistance values should be between 4K ohms and 200K ohms. If either of the resistance values is outside this range, there is a problem with the board. b. Measure the resistance between Pin 13 and Pin 8 on the 26LS31 chip on the AFI board. Likewise, measure the resistance between Pins 14 and 8. Both resistance values should be greater than 20K ohms. If either of the resistance values is less than 20K ohms, there is a problem with the board. c. Replace the AFI board, if necessary, and re-insert it into the frame. 6. Have the operator at the MSC switch active controllers* in the RCF. Repeat Step 5 for the other UN166 board. 7. Connect the LAQS test equipment to the LAC alarm bus as described in paragraph E. Verify that all LACs in the site are properly indicated in the Addresses of On-Line LACs section of the main LAQS menu. 8. Select LAQS Option 5, Re-query for Listening LACs, to verify the integrity of the alarm interface. This option will cause the test set to repeatedly search for LACs on the alarm bus, reporting any inconsistent results. This feature is especially useful for detecting intermittent conditions. Allow the software to run for several minutes before concluding that all LACs are reporting correctly. 9. If inconsistencies are reported, attempt to isolate the problem by disconnecting and re-connecting LAFs and/or LACs from the alarm bus until all inconsistent alarm reporting is eliminated. * Issue ECP command SWITCH:Cell,CSC.

Once a problem LAC is isolated, reset its microprocessor by powering it down, waiting 10 seconds, and re-setting the breakers. After re-setting the LAC, bring up two radios and allow at least 2 minutes for any alarms to clear. !CAUTION:Make sure that all radios are turned off before re-applying power to the LAC. 11. If the LAC continues to report inconsistently after it has been reset, double check its address and inspect the LAC alarm cable and connections (See Figure 22-9). Connect it to the bus by itself and check the integrity of the LAC alarm cable by moving it to another LAC. If the problem moves with the cable, replace the cable. If the problem clears, move the cable back and suspect a problem with the LAC. 12. Power down the suspect LAC and disconnect the alarm cable from the top-most 9-pin D-sub connector at the back of the AYG3 pack (J10) (See Figure 22-6). a. Using an ohmmeter, measure the resistance from Pins 1 and 2 to ground on LAC connector J10. (Use the connector shell for ground.) Both resistance values should be greater than 20K ohms. If either value is less than 20K ohms, there is a problem with the LAC. b. Likewise, measure the resistance from Pins 3 and 4 to ground. Both resistance values between 4K ohms and 200K ohms. If either of the resistance values is outside this range, there is a problem with the LAC. 13. If the LAC resistance values check out OK, remove the cover over the microprocessor on the side of the AYE1 pack in the LAC. Check for bent pins on the processor chip, or other obvious problems. 14. Once all faulty LACs have been isolated, reconnect the other LAF and/or LACs to the alarm bus. Verify with the MSC that none of the connected LACs are generating alarms and that only the disconnected LACs are generating SANITY alarms. 15. Replace all faulty LACs, making sure to correctly set the address on any new LACs. Verify that all LAC SANITY alarms have been cleared. Use the LAQS equipment, Menu Option 5, to verify the integrity of the LAC alarm bus. NOTE:If replacements are not available, leave all defective LACs disconnected from the alarm bus until they can be replaced.

Disconnect the alarm cable at J1 of LAF0, so that only LAF0 is connected to the alarm bus. (Expect all LACs in the disconnected LAF to give SANITY alarms at the MSC.) 9. If the LACs in LAF0 stop giving SANITY alarms, there is a problem in LAF1. If the alarms from the LACs in LAF0 persist, there is a problem in LAF0. Connect the problem LAF to the alarm bus, leaving the other LAF alarm cable disconnected. 10. Isolate a faulty LAC or LAC alarm cable by disconnecting LACs from the alarm bus, one LAC at a time. Disconnect the alarm cable from the top-most 9-pin D-sub connector at the back of the AYG3 pack (J10) (See Figure 22-9).

During the maintenance period, have the MSC configure all of the radios on the LAC. Using the switch on each radio, turn off all but one and measure the output power of each radio at the J4 antenna connector to be sure that the LAC is operating within its rating of 240 watts for a full-power LAC or 100 watts for a half-power LAC, taking into account the insertion loss from the LAC output to the J4 antenna connector. 2. In addition to measuring the output power at the J4 antenna connector, verify that the insertion loss between the LAC and the J4 antenna connector is correct by measuring the power on the output end of the first cable leaving the LAC. NOTE:When measuring RF power, always allow margin for measurement uncertainty; for example, assuming an uncertainty of 5%, be sure the power does not exceed 95% of rating. If it is high, readjust the power. 3. If the LAC is operating within its rated output power, suspect a problem with one or both of the UN166 AFI boards. 4. Make sure that the AYD5 Paddle Board is properly seated on the RCC backplane in the Radio Channel Frame. 5. Remove the inactive UN166 AFI board from the Radio Channel Frame. a. Using an ohmmeter, measure the resistance between Pin 1 and Pin 8 on the 26LS32 chip on the AFI board. Likewise, measure the resistance between Pins 2 and 8. Both resistance values should be between 4K ohms and 200K ohms. If either of the resistance values is outside this range, there is a problem with the board. b. Measure the resistance between Pin 13 and Pin 8 on the 26LS31 chip on the AFI board. Likewise, measure the resistance between Pins 14 and 8. Both resistance values should be greater than 20K ohms. If either of the resistance values is less than 20K ohms, there is a problem with the board. c. Replace the AFI board, if necessary, and re-insert it into the frame. 6. Have the operator at the MSC switch active controllers* in the RCF. 7. Repeat Step 5 for the other UN166 board. * Issue ECP command SWITCH:Cell,CSC.

This condition will not occur as long as the LAU FAN (See Figure 22-12)and cell site air conditioning are both functioning properly. Symptoms: 1. MINOR, MAJOR, or CRITICAL alarms at the MSC 2. LAU fan failure 3. Cell site air conditioning failure Procedure: 1. An LAU fan (See Figure 22-12) failure is the most probable cause of Thermal alarms. An air conditioning failure may result in a low-level (MINOR) Thermal alarm but should not progress to MAJOR or CRITICAL alarms as long as the LAU fan is functioning normally. 2. During normal operation, LAMs may be warm to the touch, but should not be so hot that you cannot leave your hand in contact with them. 3. If the LAU fan and air conditioning are both functioning properly, and the LAMs appear to be too hot, check the output power of the LAC to verify that it is being operated within its rating. Processor Alarm Procedure Symptoms: 1. Linearizer (LZR) LED lights. 2. MINOR alarms reported at the MSC. Probable Causes: 1. FAC/FLD switch is in the wrong (FAC) position. 2. The LAC microprocessor is issuing an alarm. Checking the FAC/FLD Switch The FAC/FLD switch is set to the FAC position during LAC production and should be set to the FLD position before leaving the factory. If this switch is in the wrong position it will be evident by a continuously lighted LINEARIZER LED at LAC installation. 1. The FAC/FLD switch is located on the AYE1 circuit pack (See Figure 22-10), which is the 2nd pack from the left in the linearizer. The switch is accessed through an opening located on the side of the pack at the top rear corner, near the microprocessor cover plate. Remove a few
Lucent Technologies — ProprietarySee notice on first page22-40 401-660-100 Issue 11 August 2000Linear Amplifier Circuit (LAC) MaintenanceLAMs near the bottom of the LAU and use a flashlight to check the position of the switch. (There are actually two switches, but only the upper one is used.) Insert a scribe, or other pointed tool, into the circular indent in the upper slide switch, making sure that the switch is positioned toward the front of the LAC. 2. If the position is wrong, change it and check to verify that the alarm has cleared. (In some cases it may take a few minutes for the alarm to clear.) NOTE:In recently produced LACs the FAC/FLD switch was moved to the front of the Linearizer (See Figure 22-10) to allow easier access. LACs with this feature have a 6-position dip switch in place of the 5-position switch. The top switch, labeled "1", is used for the FAC/FLD setting and the bottom 5 switches, labeled 2-6, are used for the address setting. The top switch should be in the "0" position for field operation. LACs with this feature are clearly marked. Checking the Version of the Microprocessor Firmware A/B Series LACs with AYE1 circuit packs prior to Version 7 do not store processor alarm information, making it impossible to tell if the LAC has issued a Processor alarm. If the SERIES number on the AYE1 circuit pack is from 1 to 6 (the label is located on the top front corner of the pack), the microprocessor should be replaced with one having the latest firmware. (If the AYE1 pack does not have a SERIES number label, it is an old version - replace the processor.) Refer to AT&T Engineering Change Procedure ECP-C20144CB for details on how to replace the microprocessor. NOTE:The LAC Alarm Query System (LAQS) may display an error message when attempting to communicate with an LAC which does not store processor information. When upgrading the microprocessor: 1. Be sure to turn off all radios and power down the LAC beforehand. 2. After replacing the microprocessor, be sure to follow the instructions for labeling the AYE1 circuit pack to show that it has been upgraded. 3. Before re-applying power, make sure that all radios are off. Re-apply power first to the Linearizer and then to the LAU. 4. Turn on 2 radios and allow the LAC to adjust for 2 minutes. Bring up all radios. If the alarm repeats, proceed with the next section to query the microprocessor alarm registers to determine if the LAC has issued a Processor alarm.

If the alarm remains clear, try other combinations of radios as described in the Radio Control Procedure. Be sure the LAC is not reporting a SANITY alarm at the MSC. 6. After leaving the site, continue to monitor the LAC from the MSC to determine if the alarm has cleared. If the alarm returns, go back to the site and query the microprocessor.Checking the Microprocessor Alarm Registers The LAC's microprocessor stores the current LAC alarm status as well as information about what caused Processor MINOR alarms. To access this information, the LAF frames must be disconnected from the alarm bus and connected to a FITS computer via a customized IEEE-488 to RS-422 Converter. Even though this will result in SANITY alarms at the MSC for all LACs, this procedure will not interfere with live traffic at the cell site. An LAC should not be replaced for MINOR alarms unless it has issued a Processor alarm.* To read the LAC Processor alarm registers, connect the FITS computer to the LAC alarm bus and run the LAQS software. After reading the Processor Alarm Registers, refer to the following sections for corrective actions. Refer to Paragraph E for detailed instructions on using the LAQS software. * Except for A/B-Series LACs with a LAM Bias Fault (see LAM Bias Fault procedure).

Therefore, do not turn off the LAC prior to checking the alarm registers. Microprocessor Alarm Registers - Corrective Actions NOTE:For 10-LAM LACs, verify that the LAC is configured with a 2-dB attenuator on the AYF4 circuit pack J35 connector. For 20-LAM LACs, verify that the attenuator is not installed. See the LAC Removal/Installation ProceduresNOTE:Intermittent Processor Alarms: Intermittent Processor alarms are generally not service affecting, but may lead to a service affecting condition if they persist. A small number of Processor alarms is not usually cause for concern, since they may occur, occasionally, as a result of transient traffic conditions. Symptoms: 1. Intermittent MINOR alarms reported at the MSC. 2. Alarms in any Processor Alarm Register. 3. Other alarm procedures have failed to uncover problems. Procedure: 1. Reset the Processor Alarm Registers by using the LAQS software or by powering down the LAC. Refer to Paragraph E for a description of the LAQS software. 2. Continue to monitor the LAC from the MSC for intermittent MINOR alarms. 3. If intermittent MINOR alarms continue to be reported, return to the site and read the Processor Alarm Registers again. 4. If the total number of Processor alarms is greater than or equal to the number of MINOR alarms reported since the last site visit, the problem is internal to the LAC. Replace the LAC. 5. If the number of MINOR alarms reported since the last site visit is greater than the number of Processor alarms, suspect a problem with one of the LAMs. Perform the Radio Control Procedure to isolate the bad LAM. 6. Reset the Processor Alarm Registers before leaving the site.

Numerous Processor alarms. Suspect: 1. A blown fuse on the AYG3 circuit pack. 2. A blown FCA fuse on the front panel of the Linearizer. Procedure: 1. Before checking any fuses, inhibit call processing and turn off all radios on the LAC. Open all 5 breakers which feed the LAC. 2. For Register 3 alarms, check the FCA fuse on the front of the Linearizer. Replace it with a 32V/10A AGC style fuse if blown. 3. On newly built LACs, there is a window on the left side of the Linearizer sheet metal which allows access to a row of fuses in the AYG3 circuit pack.Remove the screws holding the LAC in the frame and carefully pull it out on the slides. Carefully pry off the spring-loaded fuse cover on the side of the AYG3 pack, exposing a row of seven fuses in sockets. 4. Use a pair of needle-nose pliers to pull out F8, the second fuse from the top, and F7 the third fuse from the top. They are both 3A Buss PC fuses with part number BK/PCB-3. If either of these fuses is blown, replace both of them with Bussman BK/PCE-5 fuses. Be careful not to drop a fuse into the casting. 5. Reset the circuit breakers (with all radios off). Reset the breaker supplying the Linearizer first. 6. Turn on 2 radios and wait 2 minutes to allow the LAC to adjust. 7. Exercise the LAC with various numbers of radios, as described in the Radio Control Procedure to confirm that the alarm condition does not re-occur. !CAUTION:The other AYG3 fuses should not be replaced in the field. If one of these fuses blows, it may have been caused by a short circuit inside the Linearizer. If any of these fuses fails, the LAC should be replaced. Other Continuous Processor Alarms: Symptoms: 1. Continuous LINEARIZER LED.
Lucent Technologies — ProprietarySee notice on first page22-46 401-660-100 Issue 11 August 20002. Numerous Processor alarms. Procedure: 1. Be sure to rule out problems with the FCA and AYG3 fuses, as described above. 2. If the LINEARIZER LED is continuously lighted and the LAC has issued a large number of Processor alarms, then the LAC should be replaced. The LAC Alarm Query System (LAQS) The LAC's microprocessor stores the current LAC alarm status as well as information about what caused Processor MINOR alarms. The LAQS system is a testing tool which connects to the LAC alarm bus, allowing the user to communicate directly with the LAC. To access this information, the LAF frames must be disconnected from the alarm bus and connected to a FITS computer via a customized RS-232 to RS-422 Converter. Even though this will result in SANITY alarms at the MSC for all LACs (during the time that the alarm cable is disconnected), this procedure will not interfere with live traffic at the cell site. !CAUTION:The information stored in the Processor Alarm Registers is lost when the LAC is powered down. Therefore, do not turn off the LAC prior to connecting the LAQS system. NOTE:Contact your AT&T Account Executive for information on how to obtain the following equipment. Required Equipment: ■Any Computer With a 9-Pin Serial Interface ■LAWX Interface Kit (ED3R102-30 G1). Installation: 1. Disconnect all LAF frames from the alarm bus by removing the connector at J104 on the top of the RCF frame. This will result in SANITY alarm reports at the MSC for all LACs while the cable is disconnected. 2. Connect the RS-422 cable from the converter box to the free alarm bus connector on the last LAF frame: J1 on LAF0 if equipped with only one frame, J2 on LAF1 if equipped with two frames. 3. Connect the FITS computer to the converter box with the IEEE-488 cable.

Differences in Alarm Reporting Between A/B-Series and C-Series LACs 0Although all LACs issue the same types of alarms, there are differences between C-Series and A/B-Series LACs which affect how failures are reported under the various categories of alarms (MINOR, MAJOR, and CRITICAL), as well as which LAC LEDs are lit under various trouble conditions. These differences are summarized below: Visual Alarm Indications  0As an aid in troubleshooting, alarm and status information is provided in the form of visual LED indicators on the LAC. Five status LEDs are located on the faceplate of the Linearizer (LZR) cabinet and twenty LEDs are located around the circumference of the donut-shaped AYM power distribution board on the LAU, one for each of the LAM positions.

Linearizer Faceplate LEDs  0There are five LEDs on the front faceplate of the Linearizer; four of them are labeled the same on all LACs, even though the conditions under which they light are somewhat different for C-Series LACs than for earlier vintages, as described above. The position of the LEDs and their labels is shown below, followed by a description of their functions.Input Drive - The RF input to the LAC from the Preamplifier is too high. Fans - Provided on C-Series LACs and used to indicate a fan failure. The associated LED is also lighted to indicate which fan has failed; either the LAU, LZR, or Pre-Amplifier fan. NOTE:The preamp fan alarm is associated with LAF position 0 only. Antenna - Present but unused on A/B-Series LACs. Linear Amplifier Unit (LAU) - Indicates a failure in the LAU; either the LAU fan, LAM failure(s), or a high temperature condition, which can generate either a MINOR, MAJOR, or CRITICAL alarm, depending on temperature level. It is also lighted in the case of a LAM bias voltage problem, which might be due to a power supply failure or due to a fault in one of the LAMs or its associated power connector. PRE-AMPLIFIER - Any failure associated with the Preamplifier; either the preamp fan (LAF position 0 only), one of the two preamp fuses, or the preamp itself (a failure in one side of the internally redundant amplifier, including loss of power, is detected).

Linear Amplifier Unit (LAU) LEDs  0Associated with each LAM on the circular AYM power distribution board in the LAU (Linear Amplifier Unit), is a fuse and an LED which is lighted whenever a loose or blown fuse or a failed LAM is detected. A MINOR, MAJOR, or CRITICAL alarm is issued depending upon how many LAMs have failed and whether the LAC is equipped with 10 LAMs or 20 LAMs. In order to detect a failed LAM, at least one radio with a LAC output power of at least 15 watts must be applied to the LAC. However, no RF is needed to detect a blown fuse. Below is listed the number of failed LAMs required to generate a specific type of alarm for a LAC equipped with either 10 or 20 LAMs. !CAUTION:For LACs equipped with 10 LAMs, each empty slot must be equipped with a good fuse to avoid false alarms. Do not remove fuses from empty LAM positions even though doing so may not result in an immediate alarm indication. Field Replaceable Fuses  0All fuses in the LAC are mounted in the AYG3 circuit pack in the Linearizer. There are two different types of field replaceable fuses: ■AGC style fuses mounted in fuse holders, which are accessed by removing the grille from the front panel of the Linearizer. These are glass fuses which can be visually inspected. Table 22-3.

On recently manufactured LACs these fuses can be accessed through a cover plate on the left side of the Linearizer. These fuses can only be checked with an ohmmeter.■Before checking any Linearizer fuses, inhibit call processing and turn off all radios on the LAC. Open the 30 amp LAC circuit breaker which feeds the Linearizer. Linearizer Faceplate Fuses  0Beginning with the 1C LAC, an extra fuse (marked "FCA") was moved from the inside of the AYG3 circuit pack to the front panel of the Linearizer, allowing it to be changed in the field. The position of the fuses and their labels on the front panel of the Linearizer are shown below, followed by a description of their functions. FCA - Protects the Final Correction Amplifier in the Linearizer. This fuse may be blown if the LAC is overdriven. This fuse is only accessible on C-Series LACs. Linearizer Fan - Protects the fan in the Linearizer. This fuse may blow if the fan fails or if it becomes blocked. Pre-Amplifier - There are 2 preamplifier fuses, one for each of the two redundant RF power paths in the preamp. These fuses may blow if a preamp fails or there is a short in the preamp power cable. If one of these fuses fails, they should both be replaced. Linear Amplifier Unit fan - Protects the fan in the Linear Amplifier Unit. This fuse may blow if the fan fails or if it becomes blocked.

If one of the other fuses blows, it may be caused by a short circuit inside the Linearizer. If any of these other fuses fails, the LAC should be replaced. LAC Alarm Detection and Reporting System - Technical Description This section provides a technical description of how LAC alarm information is transmitted between the LAC and the MSC over the alarm interface bus, and how the alarms are reported at the MSC. LAC Alarm Reporting  0Each LAC in the cell site transmits one of four alarm levels to the MSC: NORMAL, MINOR, MAJOR, or CRITICAL and 10/20 Configuration Status (indicating how many LAMs the LAC is equipped with). In addition, a WARNING alarm is transmitted if a LAC overdrive condition is detected. A SANITY alarm is transmitted by the UN166 AFI board if a LAC fails to respond to a status query. This alarm information can be viewed at the MSC in a number of formats, each of which provides a different level of detail. These are: the Maintenance CRT (MCRT), the Receive-Only Printer (ROP), the LAC alarm summary report (LACSUM), and the detailed LAC alarm report (LACALM). The MCRT and ROP outputs are described below. For details on the LACSUM and LACALM reports, refer to paragraphs A and B. Alarm Scanning  0The UN166 AFI board, located in the Radio Channel Frame (RCF), queries each of the LACs over the RS-422 LAC alarm bus under control of the UN524 Core Processor board. Each allowable LAC address is queried every 2 seconds for alarm status updates. Four bits are transmitted for each of the LACs in the cell. Two bits are used to indicate the LAC alarm state (NORMAL, MINOR, MAJOR, or CRITICAL), one bit is used for 10/20 Configuration Status, and one bit is used for RF Overdrive WARNING. Each query takes approximately 25 msec and is repeated twice in succession for each of the allowable LAC addresses.
Lucent Technologies — ProprietarySee notice on first page22-56 401-660-100 Issue 11 August 2000NOTE:Prior to Cell Site Software Release 4.3, 32 addresses were reserved for LACs. With the introduction of Release 4.3, that number was reduced to 7, numbered 0 through 6. Alarm Status Registers  0Status registers on the AFI board store the current alarm information for each LAC. In addition to alarm state, 10/20 configuration, and WARNING, a register is also reserved for a SANITY alarm. A SANITY alarm is set if a LAC address which is supposed to be equipped fails to respond to a status query. Each alarm status register can store 8 bits of information. Since the four possible LAC alarm levels require 2 bits per LAC, each alarm status register contains alarm status for 4 LACs. LAC warning registers handle 8 LACs per register (1 bit per LAC) as do LAC configuration and LAC sanity registers. The registers are continuously scanned and any changes in state are reported to the MSC and printed out on the ROP. NOTE:On the ROP output, the status registers are referred to as offsets rather than registers. Each of the alarm status registers is assigned a number. Since the number of allowable LAC addresses changed from 32 to 7 with the introduction of Series II Cell Site Software Release 4.3, the address numbers of the LAC alarm status registers also changed. The alarm status register numbers associated with the LACs, for software versions before and after Release 4.3, are summarized below: Table 22-4.

Lucent Technologies — ProprietarySee notice on first page401-660-100 Issue 11 August 2000 22-57Maintenance CRT (MCRT):  0The MCRT terminal* in the MSC serves as the primary interface between the cellular system and the system operator. It is used for most administrative and diagnostic tasks and may be used to display status information for all cells serving the MSC. If the MSC receives an alarm from any piece of equipment or sensor in the system, that alarm state will appear at the top of the screen. The operator may then call up a visual display which indicates the cell site which issued the alarm. The operator may then display another screen showing the alarm status of all equipment in that particular cell site. This screen will display a flag indicating the particular piece of equipment in the cell which issued the alarm. If a LAC is generating the alarm, the operator may then display another screen to determine which LAC in the cell is in alarm. The MCRT only shows which piece of equipment is generating an alarm. It does not show LAC alarm levels, WARNINGS, SANITY, or 10/20 configuration and shows no history. The MCRT, therefore, cannot be used to find the root cause of a LAC alarm. However, since the MCRT display is updated with current alarm information every 4 seconds, the system operator can use it to monitor the current alarm status of a LAC while in communication with maintenance personnel at a cell site. ROP Messages for the LAC  0As discussed above, the ROP prints out a message every time there is a change in the alarm status of a LAC. This information is automatically provided to the ECP by the cell site core software, which polls the registers in the AFI board once every 4 seconds. In ROP terminology, a "NORMAL" condition exists when a LAC is not generating any alarms, and no SANITY or overload WARNING conditions exist. "OFF NORMAL" indicates that the LAC is issuing an alarm. A message is printed only when a change in one of the alarm states occurs, and periodically, once an hour, when the ECP actively queries each cell site for its alarm status. Therefore, if an alarm condition remains continuous, it will be reported by the ECP once an hour. Paragraphs A and B describe how to determine if a LAC alarm is continuous. *For a detailed description of MCRT operation, see AT&T 401-610-151, AUTOPLEX Cellular Telecommunications Systems Daily Operations Guide.
Lucent Technologies — ProprietarySee notice on first page22-58 401-660-100 Issue 11 August 2000LAC alarm message on the ROP: 0The LAC alarm message on the ROP contains 5 lines. The first line gives an indication of the alarm level, the time at which the alarm was printed (in minutes past the hour), and the number of the cell site which generated the alarm. Alarm levels are indicated by a single asterisk for MINOR (*), two asterisks for MAJOR (**), and an asterisk with a C in front for CRITICAL (C*). A SANITY alarm is also tagged as a MAJOR alarm (**), printing out SANITY after the LAC number, as in example 3 below. This is why SANITY alarms are labeled MAJS on the LACSUM report. On the second line, the "OFFSET" and "BIT" numbers indicate which of the storage registers described previously has changed. The BIT number, together with the OFFSET number, can be used to identify the specific LAC which issued the alarm. The BIT number can be ignored, however, since the LAC number is given directly in line 3. The OFFSET number is used to determine whether the change in status involved alarm level, sanity, 10/20 configuration, or an overdrive warning. The third line indicates which LAC issued the alarm. The fourth line shows whether the alarm has just been issued (OFF NORMAL) or has just cleared (NORMAL). The last line shows the date and time at which the alarm was printed on the ROP along with a number used to uniquely identify the event. NOTE:Since the printing of alarm information by the ECP has a low priority relative to call processing activities, the time at which the alarm was printed on the ROP may lag the time at which the alarm was initially reported by the cell site. Three examples of ROP messages are shown below:

If they are to be installed as low-power (10-LAM) LACs, an in-line SMA attenuator must be installed in series with a coaxial cable in the Linearizer and, on C-Series LACs, the 10/20 switch on the front of the circuit AYM board must be changed to the 10 position. To change back to a 20-LAM LAC, the in-line attenuator must be removed and the switch returned to the 20 position. A label (CONVERSION RECORD) is provided on the front face of the Linearizer cabinet on C-Series LACs and should be marked with the date of any 10/20 conversion. A suitable label should also be placed on any A/B-Series LACs which are converted. NOTE:Any new C-Series LACs shipped from the factory as replacements will not have attenuators. The attenuators may be obtained from AT&T as a spare part, Comcode 406825794 or 406822064. Any new C-Series, half-power LACs ordered will have the attenuator shipped loose as part of J41660CA-1, List 3 or J41660CA-2, List 4.
