TransCell 1900TM Operation and Maintenance Manual 1000497APage 1-4TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE1.4 SYSTEM OVERVIEWThe TransCell 1900TM System provides an economical means for building out bothcoverage and capacity for TIA/EIA-136 TDMA wireless communications. The TransCell1900TM System uses distributed RF elements to receive and transmit TDMA-based signalsat remote sites, and microwave data links for two-way transport.  These signals betweenthe remote sites and the Base Transceiver Station (BTS) interface at the designated hubsite.The system software oversees all elements of the TransCell 1900TM System and providesoperational data to a Network Operations Center (NOC). The software also provides themeans to remotely set all system operational parameters and to locally install softwareupgrades. All user communications are conducted through an Ethernet® TCP/IP ASCIIinterface.1.4.1 System ConfigurationA typical TransCell 1900TM System configuration is shown in Figure 1-1. The basic systemconfiguration is a Hub/Remote Pair (HRP). Each HRP consists of a Hub Subsystem (eithera Master or Slave) and a Remote Subsystem connected with a microwave data link. EachHub Subsystem (Hub 1 through Hub n) is directly connected to a BTS.Monitoring and control access to the TransCell 1900TM System is provided both locally andremotely. Local access for monitoring and control of each HRP is provided at both the Huband the Remote subsystems in the form of an Ethernet port. Any computer meeting theminimum configuration requirements (see paragraph 1.4.5.1) with the HRP User Interface(HUI) software installed and the appropriate list of Internet Protocol (IP) addresses can beconnected for password-controlled access.At the NOC, the System Element Manager (SEM) software, installed on an appropriatelyconfigured computer, continuously captures alarm data from the Wide Area Network(WAN) for each HRP. The alarm data is displayed for review and acknowledgment via theSEM user interface, and it is made available to the NOC’s Operation Support Services(OSS). A computer with the HUI software installed also may be activated at the NOCC formonitoring and control access to operating parameters of each HRP.

This section itemizes some of the main system software functions and their defaultruntime status.  It is recommended that the TransCell 1900TM use the system defaultsduring normal operation.  See Table 3-2 below.Table 3-2.

Specific alarms may be enabled or disabled at aparticular HRP using the HRP User Interface (HUI).  All alarms are initially enabled.  It isrecommended that all alarms remain enabled during normal system operation.  For moreon enabling and disabling particular alarms, see the SEM/HUI User Manual.  A completealarm list and troubleshooting guide can be found in section 4.4.2.5.
TransCell 1900TM Operation and Maintenance Manual 1000497APage 3-5TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE3.6.1.2 Autolevel FunctionalityThe Forward Path Automatic Power Leveling (“Autolevel”) function regulates power levelsthroughout all Hub Remote Pair (HRP) forward carriers to maintain a specific output ateach Remote Transmitter Antenna Port, thereby stabilizing the system’s RF footprint whilemaintaining signal quality throughout the system.  It does so serially, beginning with HRPcarrier one and cycling through all six carriers in turn.  The frequency of each full visitationcycle can be modified.  Also under user control is the Autolevel Setpoint, which is the RFpower level to be maintained at the Transmitter, and the Autolevel Threshold, which is themargin under which the Autolevel routine will consider the measured RF power closeenough to the desired level.  For default settings, see Table 3-2.  Autolevel can be enabledand disabled using the HRP User Interface (HUI).  It is recommended that this functionremain enabled during normal operation.  For a complete list of HUI commands and validparameter ranges, see the SEM/HUI User Manual.NOTEAutolevel is not intended to prohibit rapid RF power increases, but tocompensate for gain variation due to temperature fluctuation or BaseStation Radio replacements.  Instantaneous overpower conditions arehandled autonomously at the Remote Transmitter via PowerAmplifier shutdown.  Shutdown will occur at an output power of 37.2watts peak (worst case) measured at the enclosure antenna terminal.However, the Autolevel function does detect when an overpowercondition has passed, and will return the Transmitter to itsoperational state.3.6.1.3 Autosync FunctionalityThe Microwave Datalink Automatic Synchronization ("Autosync”) function uses a staggeredcycle operation to autonomously lock Hub and Remote Data Link Forward and Reversepaths.  This function uses a fixed frequency approach, so it is imperative that both the Huband Remote Data Link Modules (DLM) are tuned to the correct channels. Default channelsare 1 and 6, and are user controllable.  Typical time to completion of a successful Data Linklock from cold start (both Hub and Remote simultaneously powered on) is 2 minutes.  If nolock occurs within 11 minutes at the Hub Subsystem, Autosync enters a loop-back mode todetermine if there is an equipment problem with the local DLM.  After the success orfailure of a local loop-back test is noted in the corresponding HUB DLM OUTPUT orREMOTE DLM INPUT ALARM, Autosync restarts the lock process.  This cycle is repeatedindefinitely until the Data Link is locked between Hub and Remote DLMs.  AlthoughAutosync can be enabled and disabled via the HRP User Interface (HUI), it should never bedisabled in normal operation.  For a complete list of HUI commands and valid DLMparameter ranges, see the SEM/HUI User Manual.NOTEIn simulcast configurations the loop-back test may periodically de-sense the donor base-station.  It is recommended that, upon receivinga loop-back alarm in a simulcast system, the operator disable furtherloop-back testing until the alarm is resolved on site.
TransCell 1900TM Operation and Maintenance Manual 1000497APage 3-6TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE WARNINGDisabling the Autosync function may lead to extended down time, asany momentary break in Data-Link lock would then require a sitevisit to the Remote Enclosure to re-enable Autosync and re-lock theData-Link.  Autosync should only be disabled during specificinstallation procedures called out in the TransCell 1900TMInstallation Document #1000462.3.6.1.4 Reverse Autogain FunctionalityThe Reverse Path Automatic Gain (“Reverse Autogain”) function uses a noise figuremeasurement to adjust the reverse HRP carrier gain to maintain specified sensitivitylevels.  Like Autolevel, Reverse Autogain has a user controlled visit time, gain levelsetpoint, and toggle state.  For default settings, see Table 3-2.  For a complete list of HUIcommands and valid Reverse Autogain parameter ranges, see the SEM/HUI User Manual.3.6.1.5 Forward ContinuityThe “Forward Continuity” function is used to detect a lost DCCH signal and to determinethe exact location of any disconnect within the system’s forward path.  When a fault isdetected, an alarm is generated and sent to the System Element Manager (SEM) fordisposition.  This function has two main time cycles.  Operating outside the MaintenanceWindow, Forward Continuity validates power levels at each point in the forward pathoccupied by the DCCH only.  This phase is non-intrusive to the system.  Operating Insidethe Maintenance Window, Forward Continuity uses the DCCH and internal test tones tovalidate the power levels of each HRP forward carrier.  During this phase, call processing isbriefly interrupted at the beginning and end of the Maintenance Window. ForwardContinuity is enabled by default and can be enabled and disabled via the HRP UserInterface (HUI).  For a complete list of HUI commands and valid parameter ranges, see theSEM/HUI User Manual.3.6.1.6 Reverse ContinuityThe “Reverse Continuity” function is used to detect and determine the location of anydisconnect with the system’s reverse path.   When a fault is detected, an alarm is generatedand sent to the System Element Manager (SEM) for disposition.  This function brieflyinterrupts call processing at the beginning and end of the Maintenance Window to run therequired RF testing.  Reverse Continuity is enabled by default and can be enabled anddisabled via the HRP User Interface (HUI).  For a complete list of HUI commands and validparameter ranges, see the SEM/HUI User Manual.3.6.2 Software System MaintenanceThis section delineates specific system procedures likely to be needed during routinemaintenance of the TransCell 1900TM system.  For a more complete list of system setupprocedures, see the Transcell 1900TM Installation Document #1000462.3.6.2.1 Defining the Maintenance WindowThe Maintenance Window is a period of time in which an HRP may audit the system’schannels in a manner that prohibits phone calls.  As is discussed in sections 3.6.1.5 and3.6.1.6, this disruption occurs at each end of the Maintenance Window.  If the Maintenance

Widening the Maintenance Windowimproves system availability, as channel audits are performed over a more statisticallysignificant portion of each day.  The Maintenance Window start and end times may bemodified via the HRP User Interface (HUI). For a complete list of HUI commands and validparameter ranges, see the SEM / HUI User Manual.3.6.2.2 Changing and adding TDMA channelsThe procedure for adding TDMA channels can be found in the Transcell 1900TMInstallation Document.  The procedure for changing channels is as follows.a. Login to target Hub Remote Pair (HRP) using the HRP User Interface (HUI).b. Type GET HTM BAND and GET RTM BAND to see if the HRP is in the desired PCSband.c. If the HTM and RTM are in the incorrect band, type SET HTM BAND X and SETRTM BAND X, where X is the desired PCS band of operation. WARNINGThis step retunes the HTM and RTM to default frequencies in thedesired PCS band, and therefore disrupts current phone traffic on allchannels.  If only a subset of carriers is to be changed, skip this step.d. Type SET HRP TDMACHAN X Y, where X is the carrier designator through theTransCell 1900TM system (1-6), and Y is the desired TDMA channel assignment.For example, to assign TDMA channel 123 to HRP carrier 6, the command wouldread SET TDMACHAN 6 123. WARNINGThe TransCell 1900TM system is a multi-band system meetingTIA/EIA-136 channel specifications.  However, it is a single bandsystem at any given time, blocking channel changes that would rangeoutside the set PCS band.  The liability for operating in a PCS bandnot licensed to the operator rests entirely with the operator.NOTEIf a Maintenance Window parameter is adjusted during the currentMaintenance Window, the desired changes will not take effect until thenew start time is reached.  Furthermore, a change to MaintenanceWindow parameter while inside the Maintenance Window triggers thetermination cycle of the current Maintenance Window.

Theuse of these channels is allowable provided the operator owns bothPCS bands in which these border channels exist.  Otherwise, the useof the TDMA border channels violates FCC 47 CFR 24.235.  See Table3-3 for a list of border channels.e. Repeat previous step for each desired channel change. WARNINGIn the event where some HRP carriers are unused, it is imperativethat these unused carriers are not mapped to TDMA channels whichare active elsewhere in that HRP.  Failure to tune inactive carriersaway from active TDMA channels may result in degraded systemperformance.Table 3-3.

For a complete list of commands, see the SEM /HUI User Manual.  The recommended method to status the entire HRP is by using thescript SYSTAT.TXT.  The contents of  SYSTAT.TXT include a few “GET” commands andseveral calls to subordinate script files, which the HUI executes in sequence.  To useSYSTAT.TXT, login to the target HRP and type @systat.txt.  There are several bundledscripts which status specific modules and groups of modules in the TransCell 1900TMsystem.  A tutorial on creating and using script files as well as a complete listing of bundledscripts can be found in the SEM/HUI Manual.3.6.2.4 Toggling Transmitter StateDuring normal operation, the Remote Transmitter Power Amplifier (PA) should alwaysremain enabled.  However, during some maintenance actions (such as removing or adding aBTS radio) the operator may wish to toggle the PA output at the corresponding HubRemote Pair (HRP) for safety purposes.  The following is the procedure for toggling one ormore PA states.a. Login to target HRPb. If all PA states require enabling, type @PAON.TXT at the HRP User Interface (HUI)command line.c. If all PA states require disabling, type @PAOFF.TXT at the HUI command line.
TransCell 1900TM Operation and Maintenance Manual 1000497APage 3-9TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE WARNINGDue to safety concerns, a manual Remote Transmitter PowerAmplifier (PA) shutdown will not be reversed by autonomous systemsoftware.  Be sure to re-enable all desired PA outputs beforereturning the TransCell 1900TM system to normal operation.Failure to do so will result in degraded call processing statistics.d. To toggle individual PA states, type SET PA STATE N B, where N is the PA number(1-6) and B is a boolean integer (0=off, 1 =on).  For example, to disable the PApertaining to carrier four, the message would read SET PA STATE 4 0.e. Repeat previous step for each desired PA state toggle.

Faults arefiltered and/or correlated by the SPM to generate alarms. All faults are monitored andlogged by the HRPs. The alarms are then reported to the MSC via the SEM workstation.Current alarms can also be gathered on site using the HRP User Interface software.  Bylogging into the local SPM via the HUI, the user is able to retrieve active alarms by typingGET LOCALSPM OPENALMS.
TransCell 1900TM Operation and Maintenance Manual 1000497APage 4-23TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE4.4.2.1 Software Fault DetectionThe SPMs in the Hub and Remote Subsystems perform fault detection on a scheduled basis.The software in the SPM monitors for new fault occurrences and absence of previousoccurrences. New faults are analyzed to determine if a new alarm should be generated. Thenon-repetition of previously detected faults results in the closing of one or more activealarms.  Each TransCell 1900TM modulel has a hexidecimal fault bitmask which can bemodified to disable certain faults at a module level.  However, this practice is notrecommended.  See Table 4-2 for a complete bitmask list. If an alarm activity must bedisabled, it is recommended that it is disabled usint the alarm number via the HUI.  Referto SEM/HUI User's Guide. The Hub and the Remote alarm statuses are reported to theSEM workstation through messages in SPM command language format.The Hub and Remote Subsystems are equipped with hardware watchdog timers. If thesoftware does not reset the watchdog timer during a preset time period, the watchdog timertimes out and issues a hardware reset to the Hub and Remote SPM processors.Table 4-2 Fault Bitmasks by ModuleModule BIT FaultLVPS [0] 8 Volt Fault for both Prim/Red[1] 12 Volt Fault for both Prim/Red[2] Lost AC Fault for both Prim/RedPAPS [0] Comms loss faultTTAM [0] 3 dB Loss[1] >=6 dB Loss[2] Power Disabled[3] DC Power[4] Battery backupSPM [0] Too Hot[1] Too Cold[2] No CommsPower Amp [0] Over Temperature Fault[1] Input Over Power Fault[2] Output Over Power Fault[3] Over Voltage Fault[4] Under Voltage Fault[5] Output VSWR Fault[6] Low Gain Fault[7] High Gain Fault[8] Warmup Period Fault[9] Reset Indication Fault[10] Spare 2[11] Spare 3

For details on alarm database utilities and functionality, see SEM / HUI UserManual.4.4.2.5 Alarm ClosingThe TransCell 1900TM system employs many autonomous functions in an effort to rectifyalarm conditions.  When an alarm condition is no longer occurring, the HRP will auto-closethe corresponding alarm.  The exception to this model is the case where one-shot alarms aregenerated.  One-shot alarms report a condition that is either rectified prior to or as part ofthe reporting process, or a condition that cannot be determined by a thirty second cycle.  Ifthese alarms were allowed to auto-close, they would only be active for one cycle, potentiallyescaping detection by the SEM operator.  Therefore, to facilitate the operator’s awareness ofpotential issues, these one-shot alarms are “user-closeable” alarms.  Except in the case ofcontinuity alarms, user-closeable alarms do not auto-close.  Alarms with “Continuity”included in their details will close if the next continuity cycle produces no errors. For moreinformation on continuity cycles, see paragraphs 3.6.1.4 and 3.6.1.5. The SEM operator mayclose any user-closeable alarm after taking the appropriate action, as necessary, to resolvethe issue.  To close an alarm, select its entry in the SEM active alarm window and click onthe “close” button which appears below the active alarm list.  The following criteria define aUser-Closeable Alarm:♦ All alarms/warnings  which include the word “Continuity” in their details section.♦ All HUB_SPM_PROCESSOR_WARNINGs♦ All REM_SPM_PROCESSOR_WARNINGs
