ADCP-75-187 • Issue 3 • September 2006 • PrefacePage viii© 2006, ADC Telecommunications, Inc.ADMONISHMENTSImportant safety admonishments are used throughout this manual to warn of possible hazards topersons or equipment. An admonishment identifies a possible hazard and then explains whatmay happen if the hazard is not avoided. The admonishments — in the form of Dangers,Warnings, and Cautions — must be followed at all times. These warnings are flagged by use ofthe triangular alert icon (seen below), and are listed in descending order of severity of injury ordamage and likelihood of occurrence.GENERAL SAFETY PRECAUTIONSDanger: Danger is used to indicate the presence of a hazard that will cause severe personalinjury, death, or substantial property damage if the hazard is not avoided.Warning: Warning is used to indicate the presence of a hazard that can cause severe personalinjury, death, or substantial property damage if the hazard is not avoided.Caution: Caution is used to indicate the presence of a hazard that will or can cause minorpersonal injury or property damage if the hazard is not avoided.Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do notlook directly into the optical transceiver of any digital unit or exposure to laser radiation mayresult. An optical power meter should be used to verify active fibers. A protective cap or hoodMUST be immediately placed over any radiating transceiver or optical fiber connector to avoidthe potential of dangerous amounts of radiation exposure. This practice also prevents dirtparticles from entering the adapter or connector. Danger: Do not look into the ends of any optical fiber. Exposure to laser radiation may result.Do not assume laser power is turned-off or the fiber is disconnected at the other end. Danger: Wet conditions increase the potential for receiving an electrical shock when installingor using electrically-powered equipment. To prevent electrical shock, never install or useelectrical equipment in a wet location or during a lightning storm. Warning: The HU is powered by 48 VDC power which is supplied over customer-providedwiring. To prevent electrical shock when installing or modifying the HU power wiring,disconnect the wiring at the power source before working with uninsulated wires or terminals. Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtailswithout severe bends.

Throughout this publication, all items referenced as “accessory items”are not furnished with the basic product and must be purchased separately. 2 SCS SYSTEM OVERVIEWThe Digivance Long Range Coverage Solution (LRCS) system is an RF signal transport systemthat provides long-range RF coverage to areas where it is impractical to place an Enhanced BaseTransceiver Station (EBTS) at the antenna site. High real estate costs and communityrestrictions on tower and equipment locations often make it difficult to install the EBTS at thesame location as the antenna. The LRCS system overcomes equipment placement problems byhubbing base stations at a central location and placing antennas at remote locations withminimal real estate requirements. The LRCS system transports RF signals to remote locations toexpand coverage into areas not receiving service or to extend coverage into difficult to reachareas such as canyons, tunnels, or underground roadways. The SCS system provides the same functionality as the LRCS system but incorporates a lowprofile, low power, low cost remote unit. The SCS system remote unit complements the highpower remote unit used with LRCS systems. The primary application includes urban areaswhere multiple, strategically placed, low power remote units provide better coverage than highpower remote units. 2.1 Basic SCS System ComponentsThe basic components of a typical Digivance SCS system and their function are shown inFigure 1-1. A basic SCS system consists of a Host Unit (HU) and a Remote Unit (RU). The HUconsists of a rack-mountable chassis that is designed for use in an indoor environment. The RUconsists of a sealed enclosure that is designed for use in an outdoor environment. Control andmonitoring functions are provided by the Digivance Element Management System (EMS).

ADCP-75-187 • Issue 3 • September 2006 • Section 1: OVERVIEWPage 1-3© 2006, ADC Telecommunications, Inc.2.2 Enhanced Base Transceiver Station InterfaceThe HU is interfaced with an EBTS over coaxial cables as shown in Figure 1-2. The EBTSprovides the RF channel inputs and outputs for a designated sector. In the forward path, the HUreceives two RF inputs from the EBTS. The HU digitizes the RF spectrum and then converts itto digital optical signals for transport to the RU. In the reverse path, the HU receives digitaloptical signals from the RU. The HU converts the digital optical signals back to two RF outputswhich are supplied to the EBTS over the coaxial cable interface. Figure 1-2. EBTS/HU Interface2.3 Subscriber Unit InterfaceThe RU interfaces with the subscriber units (cell phones) through an antenna. In the reversepath, the RU receives RF spectrum from each subscriber unit (see Figure 1-1). The RU digitizesthe RF spectrum and then converts it to digital optical signals for transport to the HU over theoptical fiber link. In the forward path, the RU receives digital optical signals from the HU. TheRU converts the optical signals to RF spectrum for transmission to the subscriber units. The RUis connected to an antenna (not provided) which transmits and receives the subscriber unit RFspectrum. 2.4 Local Management InterfaceCommunications with an individual Digivance system is supported through a local managementinterface capability as shown in Figure 1-3. A local management interface requires a PC-typecomputer loaded with the Digivance Element Management System (EMS) software. EMSprovides the various control and monitoring functions required to locally manage a Digivancesystem. The EMS computer connects directly to the HU through the computer’s RS-232 port.Operation is implemented through the EMS Graphical User Interface (GUI). The GUI consistsof a series of screens from which the user selects the desired option or function. An RS-232service port is provided on the HU for connecting the EMS computer. 20856-AHOST UNITRFENHANCEDBASETRANSCEIVERSTATIONFORWARDPATHSREVERSEPATHS

EMS provides the various control andmonitoring functions required to remotely manage multiple Digivance systems through theNOC interface. A Controller Area Network (CAN) port is provided on each HU. Up to twenty-four HU’s maybe linked together through the CAN interface and controlled by the same EMS computer. Allthe networked HU’s and the associated RU’s may be managed by connecting the EMS computerto one HU. The EMS computer provides an RS-232 port (#1) to support the interface with thenetworked HU’s. The NOC can be linked to the EMS computer through a T1 system, DS0 with RS232conversion, or some other medium. The EMS computer provides an RS-232 ASCII interfaceport (#2) to support the interface with the NOC.At the NOC, control and monitoring of the networked Digivance systems is implementedthrough a Network Element Manager (NEM) interface which requires only a VT100 terminal/emulator for operation. The NEM interface language consists of simple ASCII text strings. Allcommunications are input as either SET or GET commands which result in ASCII text stringresponses from the specified system or systems. Figure 1-5.

To support the SNMP interface, a PC-type computer loadedwith both the Digivance Element Management System (EMS) software and the SNMP ProxyAgent software is required. The EMS and SNMP Proxy Agent software plus the associatedManagement Information Base (MIB) provide the various control (Set) monitoring (Get) andtrap functions required to remotely manage multiple Digivance systems using an SNMPManager. A Controller Area Network (CAN) port is provided on each HU. Up to twenty-four HU’s maybe linked together through the CAN interface and controlled by the same EMS computer. Allthe networked HU’s and the associated RU’s may be managed by connecting the EMS computerto one HU. The EMS computer provides an RS-232 port (#1) to support the interface with thenetworked HU’s. The SNMP Manager may be linked with the EMS computer through a Local Area Network(LAN). The EMS computer provides an Ethernet port to support the interface with the LAN. The SNMP Proxy Agent supports two versions of the SNMP protocol: SNMPv1 and SNMPv2c.A facility to Register/Unregister an SNMP Manager for receiving traps is also supported by theSNMP Proxy Agent. The SNMP Manager is an option and must be ordered separately fromthe EMS software. Figure 1-6.

ADCP-75-187 • Issue 3 • September 2006 • Section 1: OVERVIEWPage 1-7© 2006, ADC Telecommunications, Inc.3 SYSTEM FUNCTIONS AND FEATURESThis section describes various system level functions and features of the Digivance system. 3.1 Fiber Optic TransportIn a typical Digivance LRCS system, the HU is connected to the RU over two single-modeoptical fibers. One fiber is used to transport the forward path optical signal. The other fiber isused to transport the reverse path optical signal. Because the optical signal is digital, the inputand output RF signal levels at the HU or the RU are not dependent on the level of the opticalsignal or the length of the optical fiber. A diagram of the fiber optic transport system for atypical Digivance LRCS system is shown in Figure 1-7. Figure 1-7. LRCS System Fiber Optic Transport - TypicalThe maximum length of the optical links is dependent on the loss specifications of the opticalfiber, the losses imposed by the various connectors and splices, and the RF modulation protocolresponse timing limitations. The basic system provides an optical budget of 25 dB (typical)when used with 9/125 single-mode fiber. In SCS applications, the forward path and reverse path optical signals from an HU/RU pair arecombined onto a single optical fiber. This is accomplished by using a passive bi-directionalWavelength Division Multiplexer (WDM) system. The optical wavelengths used in theDigivance system are 1550 nm for the forward path and 1310 nm for the reverse path. Becausedifferent wavelengths are used for the forward and reverse paths, both signals can be combinedon a single optical fiber. A WDM module (accessory) is installed with the HU at the host siteThe SCS RU, which is equipped with an internally mounted WDM, is installed at the remotesite as shown in Figure 1-8. Figure 1-8.

ADCP-75-187 • Issue 3 • September 2006 • Section 1: OVERVIEWPage 1-8© 2006, ADC Telecommunications, Inc.3.2 Control and Monitoring SoftwareThe EMS software and the SNMP Proxy Agent software provide control and monitoringfunctions for the Digivance system through the local, NOC, and SNMP interfaces. The EMSsoftware package supports the local and NOC interfaces but does not include the SNMP ProxyAgent software which must be ordered separately. Both the EMS and the SNMP Proxy Agentsoftware are required to support the SNMP interface. All software files are provided on CD-ROM’s. Software installation consists of copying the software files from the CD-ROM’s to adesignated directory on the hard-drive of the EMS computer. The EMS software provides the capability to provision and configure the Digivance system foroperation. This includes selecting a site name, setting alarm thresholds, and setting forward andreverse path RF gain adjustments. The EMS software also provides the capability to get alarmmessages (individual or summary), obtain data measurements, and to upgrade the HU/RUsystem software. All control and monitor functions (except software upgrade which is notsupported by the NOC/NEM and SNMP interfaces and HU/RU pair site number assignmentwhich is not supported by the SNMP interface) may be implemented using the NOC/NEMinterface, the SNMP interface, or the EMS software GUI. 3.3 Fault Detection and Alarm ReportingLED indicators are provided on the front panel of the HU and on the underside of the RU toindicate if the system is normal or if a fault is detected. In addition, normally open and normallyclosed alarm contacts (for both major and minor alarms) are provided at the HU for connectionto a customer-provided external alarm system. All alarms can also be accessed through theNOC/NEM interface, SNMP manager, or the EMS software GUI. 3.4 PoweringThe HU is powered by ±24 or ±48 VDC and must be hard-wired to a local DC power sourcethrough a fuse panel. A screw-down terminal strip is provided on the rear side of the HU for thepower connections. The RU is powered by 90 to 265 VAC (nominal 120 or 240 VAC), 47 to 63 Hz power. On anoptional basis, the RU may be powered by 60 to 89 VAC, 47 to 63 Hz power. A connector isprovided on the underside of the RU for the AC power connections. A 3-wire AC power cablerated for outdoor use is included with the RU. The stub end of the cable must be hard-wired tothe AC power source. 3.5 Equipment Mounting and LocationThe HU consists of a rack-mountable chassis assembly that is designed for mounting in a non-condensing indoor environment such as inside a wiring closet or within an environmentally-controlled cabinet. The HU is usually installed within 20 feet of the EBTS and may be mountedin either a 19- or 23-inch, WECO or EIA, equipment rack. The RU consists of a sealed aluminum enclosure designed for mounting in either an indoor oroutdoor environment. The RU may be mounted from a pole or the exterior side of a buildingwith the standard mounting bracket or from a strand with an accessory bracket.

Each single-band RU is equipped with the electronics tosupport one frequency band. If it is necessary to support two frequency bands (such as 800/900MHz SMR and 1900 MHz) at the same remote location, a dual-band RU can be deployed. Adual-band RU provides the electronic and optical functionality of two single-band RU’s exceptthat all the electronic and optical components are housed within a single enclosure. A dual-band SCS system consists of two standard host units and a dual-band RU that are linkedtogether over two optical fibers. At the hub site, each HU is connected to a separate EBTSfacility. The dual-band RU supports the frequency bands (such as 800/900 MHz SMR and 1900MHz) associated with the two connected HU’s. Each HU and the corresponding RU electronicsfunction independently of each other and may be managed separately using the same elementmanagement system (EMS). Figure 1-9 shows a typical SCS system equipped with a dual-bandRU. One fiber is used to transport the forward/reverse path optical signals for one SCS system.The other fiber is used to transport the forward/reverse path optical signals for the other SCSsystem.

ADCP-75-187 • Issue 3 • September 2006 • Section 2: DESCRIPTIONPage 2-2© 2006, ADC Telecommunications, Inc.1 INTRODUCTIONThis section describes the basic components of a typical Digivance SCS system including theHost Unit (HU), Remote Unit (RU), element management system, and accessories. The systemspecifications are provided in a table at the end of this section. 2 HOST UNITTwo versions of the HU are available. The rear access HU, shown in Figure 2-1, is used with800/900 MHz SMR systems. The front access HU, also shown in Figure 2-1, is used with 800and 1900 MHz systems. Connection points for the RF, optical, and alarm cables are provided onthe rear side of the rear access HU and on the front side of the front access HU. Both HUversions provide the following basic functions:• Provides a limited adjustable RF interface with the BTS. • Provides a fiber optic interface with the RU. • Digitizes the two forward path composite RF signals. • Converts the two digitized forward path RF signals to a digital optical signal. • Converts the digitized reverse path optical signal to two digitized RF signals. • Converts the two digitized reverse path RF signals to two composite RF signals. • Sends alarm information to an external alarm system through relay contact closures• Provides an RS-232 interface for connecting the EMS computer. • Provides a CAN interface for networking multiple HUs. 2.1 Primary ComponentsThe HU consists of an electronic circuit board assembly and a fan assembly that are mountedwithin a powder-paint coated sheet metal enclosure. The enclosure provides a mounting pointfor the circuit board and fan assemblies and controls RF emissions. The only user-replaceablecomponent is the fan assembly. The HU is designed for use within a non-condensing indoorenvironment such as inside a wiring closet or cabinet. The front access HU is also equippedwith a front cable management tray and vertical cable guides. 2.2 MountingThe HU is intended for rack-mount applications. A pair of reversible mounting brackets isprovided that allow the HU to be mounted in either a 19-inch or 23-inch EIA or WECOequipment rack. When the rear access HU is installed, the front panel of the HU is flush with thefront of the rack. When the front access HU is installed, the front panel of the HU is flush withthe front of the rack and the cable management tray extends 3.9 inches (99 mm) beyond thefront panel. Screws are provided for securing the HU to the equipment rack.

ADCP-75-187 • Issue 3 • September 2006 • Section 2: DESCRIPTIONPage 2-3© 2006, ADC Telecommunications, Inc.Figure 2-1. Front View of Front and Rear Access Host Units2.3 Fault Detection and Alarm ReportingThe HU detects and reports various internal and external faults including host unit fault, opticalfault, power fault, temperature fault, and RF fault. Various front panel Light Emitting Diode(LED) indicators turn from green to red or yellow if a fault is detected. A set of alarm contacts(normally open and normally closed) are provided for reporting an alarm to an external alarmsystem when a fault is detected. Both major alarm (system operation seriously affected) andminor alarm (system operation not affected or only slightly degraded) contacts are provided. Fault and alarm information may also be accessed locally through the EMS software GUI orremotely through the NOC/NEM interface or SNMP interface. An alarm history file ismaintained by the EMS software so that a record is kept of all alarms as they occur. This isuseful when an alarm is reported and cleared before the reason for the alarm can be determined. The status of the HU, the alarm state (major or minor), and other alarm information issummarized and reported over the service interface, the CAN interface, and the optical interfaceto the RU. In addition, the status of the RU is transmitted to the HU over the optical interfaceand reported over the service interface and the CAN interface. 17.1 INCHES(433 mm)3.5 INCHES(88 mm)12.2 INCHES(311 mm)FRONT PANELMOUNTINGBRACKET(BOTH SIDES)REAR ACCESS HOST UNITFRONT ACCESS HOST UNIT20666-A17.2 INCHES(437 mm)3.5 INCHES(89 mm)11.4 INCHES(290 mm)15.3 INCHES(389 mm)FRONT PANELCABLE MANAGEMENTTRAYMOUNTINGBRACKET(BOTH SIDES)

ADCP-75-187 • Issue 3 • September 2006 • Section 2: DESCRIPTIONPage 2-4© 2006, ADC Telecommunications, Inc.2.4 RF Signal ConnectionsThe RF signal connections between the rear access HU and the EBTS are supported throughfour N-type female connectors. Two connectors are used for the forward path RF signals andtwo connectors are used for the reverse path RF signals. The RF signal connections between the front access HU and the EBTS are supported throughtwo N-type female connectors. One connector is used for the forward path RF signal and theother connector is used for the reverse path RF signal. In most installations, it is usually necessary to install external attenuators to support the RFinterface between the HU and the EBTS. The HU should be as close as possible to the EBTS tominimize coaxial cable losses. 2.5 RF Signal Level AdjustmentsThe HU is equipped with several attenuators for adjusting the signal levels of the forward andreverse path RF signals. The attenuators provide an attenuation adjustment range of 0 to 31 dBand can be set in 1 dB increments. The attenuators are software controlled and are adjustedthrough the EMS software GUI, NOC/NEM interface, or SNMP interface. The host forward path attenuators adjust the level of the input RF signal(s) to the HU. Usingthe forward path attenuator, an input signal with a nominal composite signal level of –9 dBm to–40 dBm can be adjusted to produce maximum power output. Additional external attenuationis required if the input signal level is greater than –9 dBm. The host reverse path attenuators adjust the level of the output RF signal(s) from the HU andwill add from –1 dB of gain (attenuator set to 31 dB) to +30 dB of gain (attenuator set to 0 dB)to the RF output signal(s) at the HU. 2.6 Propagation DelayThe HU forward and reverse path propagation delays may be adjusted in 0.1 μsec incrementswithin a range of 0 to 63 μs. The propagation delay is software controlled and may be adjustedthrough the EMS software GUI, NOC/NEM interface, or SNMP interface. 2.7 Optical ConnectionOptical connections between the HU and the RU are supported through two optical portsequipped with UPC/SC (flat) connectors. One port is used for the forward path optical signalconnection and the other port is used for the reverse path optical signal connection. Note: The optimum composite RF input signal level for 800/900 MHz SMR systems is–20 dBm.

ADCP-75-187 • Issue 3 • September 2006 • Section 2: DESCRIPTIONPage 2-5© 2006, ADC Telecommunications, Inc.2.8 Controller Area Network Interface ConnectionController Area Network (CAN) interface connections between multiple HUs are supported bya pair of RJ-45 jacks. One of the jacks is designated as the network IN port and the other jack isdesignated as the network OUT port. The CAN interface allows up to 24 HUs to be connectedtogether (in daisy-chain fashion) and controlled through a single EMS computer. 2.9 Service Interface ConnectionThe service interface connection between the HU and the EMS computer is supported by asingle DB-9 female connector. The service connector provides an RS-232 DTE interface. Whenmultiple HUs are networked together, the supporting EMS computer may be connected to theservice connector of any one of the networked HUs. 2.10 PoweringThe HU is powered by ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The power is fed tothe HU through a screw-down type terminal strip located on the rear side of the unit. Power tothe HU must be supplied through a fuse panel such as the PowerWorx GMT Series Fuse Panel(available separately). The power circuit for each HU must be protected with a 3 Amp GMTfuse. An On/Off switch is provided on the HU front panel. 2.11 CoolingContinuous airflow for cooling is provided by dual fans mounted on the right side of the HUhousing. A minimum of 3 inches (76 mm) of clearance space must be provided on both the leftand right sides of the HU for air intake and exhaust. An alarm is generated if a high temperaturecondition (>50º C/122º F) occurs. The fans may be field-replaced if either fan fails. 2.12 User InterfaceThe HU user interface consists of the various connectors, switches, terminals, and LEDs that areprovided on the HU front and rear panels. The rear access HU user interface points areindicated in Figure 2-2 and described in Table 2-1. The front access HU user interface pointsare indicated in Figure 2-3 and described in Table 2-2.

ADCP-75-187 • Issue 3 • September 2006 • Section 2: DESCRIPTIONPage 2-16© 2006, ADC Telecommunications, Inc.EMS Software: The EMS software and the Java 2 Runtime Environment software are loadedon a CD-ROM. The EMS software provides local monitor and control functions through aGraphical User Interface (GUI) and remote monitor and control functions through the NOC/NEM interface. SNMP Proxy Agent Software: The SNMP Proxy Agent software (when included) is loaded ona CD-ROM. The SNMP Proxy Agent together with the EMS provides for remote monitor andcontrol functions through a network SNMP manager. When the SNMP interface is required forsystem operation, both the EMS software and SNMP Proxy Agent software must be installed onthe same computer. The SNMP Proxy Agent software will not function without the EMSsoftware. Control Programs: The host and remote control programs are installed by the factory in eachrespective host unit or RU. Updated versions of the host and remote control program softwarewill be provided by Customer Service on a “as needed” basis. 5.2 Software InstallationSoftware installation consists of inserting each specified CD-ROM into the computer’s CD-ROM drive and then running the software install programs. This places the EMS, Java 2Runtime Environment, and SNMP Proxy Agent (if included) software files in assigned folderson the computer’s hard drive. Software installation instructions are provided in the DigivanceElement Management System User Manual (See Related Publications section). 5.3 Computer OperationPermanent control and monitoring functions may be provided by a PC-type desk-top computerthat is permanently connected to a HU. The EMS program must be running in order for theNOC interface to function. Both the EMS program and SNMP Proxy Agent program must berunning in order for the SNMP interface to function. A PC-type lap-top computer running justthe EMS program can be used as a portable network management tool for service andmaintenance purposes. The laptop computer may be connected temporarily to the HU totrouble-shoot problems on-site and then removed when the maintenance task is completed. Thespecifications for the EMS computer are provided in the Digivance Element ManagementSystem User Manual (See Related Publications section). 5.4 Digivance EMS Computer Interface ConnectionsThe service interface connection between the EMS computer and the HU requires that the EMScomputer be equipped with a DB-9 connector that is configured to provide an RS-232 DCEinterface. A straight-through RS-232 interface cable (accessory item) equipped with a male DB-9 connector on one end and a PC-compatible connector on the other end is required to link theEMS computer to the HU. The NOC interface connection between the EMS computer and the NOC requires that the EMScomputer be equipped with a connector that is configured to provide an RS-232 ASCIIinterface. The link between the EMS computer and the NOC would generally be supported by a

ADCP-75-187 • Issue 3 • September 2006 • Section 2: DESCRIPTIONPage 2-17© 2006, ADC Telecommunications, Inc.T1 system, DS0 with RS232 conversion, or other medium. Cables and equipment (not provided)to support the RS-232 interface connection between the EMS computer and the NOC interfaceare required. The SNMP interface connection between the EMS computer and the SNMP manager requiresthat the EMS computer be equipped with an Ethernet port. The link between the EMS computerand a network SNMP manager would generally be supported by a Local Area Network (LAN).Cables and equipment (not provided) to support the connection between the EMS computer andthe LAN are required. 5.5 Digivance Software User InterfacesThe Digivance EMS provides three software user interfaces: the EMS Graphical User Interface(GUI), the Network Operation Center–Network Element Manager (NOC/NEM) interface, andthe SNMP interface. The EMS GUI, the NOC interface, and the SNMP interface provide thesame basic functions. However, the NOC interface and the SNMP interface cannot be used todownload new system software to the Digivance system. In addition, the SNMP interfacecannot be used to assign a system site number to a HU/RU pair during installation. The EMS GUI is used for local control and monitoring operations. The EMS GUI consists of aseries of displays and screens, such as the one shown in Figure 2-8, that provide the user withalarm and status information and that allow the user to set various operating parameters.Directives are implemented by pointing and clicking on the desired action and also by enteringtext in various dialog boxes. Refer to the Digivance Element Management System User Manual(see Related Publications section) for additional information. Figure 2-8. Typical EMS Graphical User Interface – Host/Remote Alarms Display

ADCP-75-187 • Issue 3 • September 2006 • Section 2: DESCRIPTIONPage 2-18© 2006, ADC Telecommunications, Inc.The NOC/NEM interface is a text-based command line interface that is used for remote controland monitoring operations (except software download). The NOC/NEM interface consists ofdefined ASCII text strings that are input as SET or GET commands followed by the action orinformation required. A text string response is received from the specified Digivance system orsystems to confirm the requested action or to report the requested information. Examples ofseveral typical NOC-NEM interface commands and the responses received are shown inFigure 2-9. The NOC/NEM interface requires only a VT100 terminal/emulator or a PC-typecomputer that is loaded with a communication software such as Procomm Plus. While primarilyintended for use at the NOC, the NOC/NEM interface commands may also be input locallyfrom the EMS computer. Refer to the Digivance Element Management System User Manual(see Related Publications section) for additional information. Figure 2-9. NOC/NEM Interface Typical CommandsThe SNMP interface is used for remote control and monitoring operations (except softwaredownload and site number assignment). The SNMP interface uses a ManagementInformation Base (MIB) to define a list of identifiers that are supported by the SNMP agent.The SNMP manager communicates with the SNMP agent over a LAN. Directives, based on theMIB identifier, are issued by the SNMP manager to the SNMP agent along with instructions toeither get the specified identifier or set the specified identifier. The directive is then executed onthe Digivance system by the SNMP agent. The SNMP agent also has the ability to sendautonomous messages (called traps) to the SNMP manager to report changes in the status of themanaged system. The SNMP manager Stargazer Version 8.0 is available from ADC for use withthe SNMP agent. Other SNMP managers are available from various network managementsoftware venders. Refer to the SNMP Agent Software User Manual (see Related Publicationssection) for additional information.

Using a DC voltmeter, verify that the DC voltage level at the HU power terminals isbetween ± 21 to ± 60 VDC (nominal ± 24 or ± 48 VDC). The DC power provided to theHU can be either polarity. 4. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured. 1.2.2 Remote Unit Installation ChecksComplete the following checks at the RU prior to starting the turn-up process: 1. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured. 2. At the AC breaker box, make sure the circuit breaker for the circuit that supplies AC powerto the RU is in the open (off) position. 2 TURN-UP SYSTEM AND VERIFY OPERATIONThe process of turning-up the system and verifying operation involves powering up the varioussystem components, verifying that the LED indicators show normal operation, setting the sitenumber and name, adjusting the RF signal levels, and adjusting the path delay. Note: When connecting the equipment to the supply circuit, be sure to check equipmentnameplate ratings to avoid overloading circuits which may cause damage to over-currentprotection devices and supply wiring. Note: SCS systems that include a dual-band RU are comprised of two systems that operateand function independently of each other. Each system can be independently turned-up,tested, and placed into service. The EMS will recognize each system regardless of thefrequency/band and will display the appropriate screens. The frequency/band can beverified by clicking on the HOST Host tab and on the REMOTE STM tab. The frequency/band for the selected system will be displayed on the right side of the screen.

ADCP-75-187 • Issue 3 • September 2006 • Section 3: OPERATIONPage 3-3© 2006, ADC Telecommunications, Inc.Each Digivance system must be turned-up separately before being networked together withmultiple systems through the CAN interface. Use the following procedure to turn-up eachDigivance system: 1. Temporarily disconnect the external alarm system or notify the alarm system provider thattesting is in progress. 2. If the HU is networked together with multiple HU’s, temporarily disconnect the CAN cablesfrom the NET IN and NET OUT ports of the HU. 3. Determine if the forward path composite input signal level at the host unit RF IN port(s) isappropriate to produce the required RF output signal level. Note that 800/900 MHz SMRhost units have two forward path RF ports. Adjust by installing an external attenuator ifnecessary. For 800/900 MHz SMR systems., the optimum input signal level is –20 dBmRefer to Section 2.1 for the calculation and adjustment procedure. 4. At the HU: Place the ON/OFF switch on the HU in the ON position (press I). 5. At the RU: Place the AC circuit breaker switch in the closed (ON) position. 6. Wait 6 to 10 seconds for the HU and the RU to initialize and then observe the LEDindicators on the HU and RU. Refer to Section 4: Maintenance for the troubleshootingprocedures if the indicators do not respond as specified in Table 3-1. Table 3-1. LED Indicator Operation at Initial Turn-Up7. Measure the input optical power level at the HU and RU and verify that the optical powerlevel received at the HU and RU is within –15 to –25 dBm. Refer to Section 4:Maintenance for the optical power test procedure. 8. Connect the EMS computer (if not already connected) to the SERVICE connector on theHU front panel. If necessary, a separate laptop computer loaded with the EMS softwarecan be temporarily connected and used to initially configure the system. Note: By default, all HU’s and RU’s are programmed with the same site number andname. This can cause problems for the EMS if multiple HU’s with the same site numberand site name are networked together through the CAN interface. It is therefore necessaryto temporarily disconnect the CAN interface cables from the HU when it is beingconfigured for operation until a unique site number and name can be assigned.

If a separate laptop computer loaded with the EMS software was used to initiallyconfigure the system, disconnect the laptop computer from the SERVICE connector. 25. Reconnect the external alarm system or notify the alarm system provider that the turn-upprocess has been completed. 2.1 Reference Procedure: Determine Forward Path Input Signal LevelThe level of the composite RF input signals received at the host unit FORWARD RF IN port(s)will vary depending on the EBTS, the cable loss, the number of channels present, and therequired forward path composite power. If maximum composite RF output is required at theRU, the level of the composite RF input signal received at the HU must fall within a range of –9to –40 dBm. If the signal level is not within this range, it must be adjusted using an externalattenuator. Note that the 800/900 MHz SMR host unit has two FORWARD RF IN ports. Use the851–869 FORWARD RF IN port to complete this procedure. Then repeat this procedure for the935–940 FORWARD RF IN port. If using the Conditioning Panel or Duplexing Panel, refer to the user manual shipped with thepanel (ADCP-75-147) for the procedures for measuring and adjusting the RF input signal levelat the HU. If connecting a single HU to a single EBTS, use the following procedure to measureand adjust the input RF signal level at the HU: 1. Connect a spectrum analyzer or power meter to the forward path output port at the EBTS.The required signal levels and test points for 800/900 MHz SMR systems are shown inFigure 3-3. The required signal levels and test points for 800 MHz and 1900 MHzsystems are shown in Figure 3-4. Note that 800/900 MHz SMR Host Units have twoforward path ports. 2. If using a spectrum analyzer, proceed to step 3. If using a power meter, measure thecomposite signal power from the EBTS and then proceed to step 5. 3. Measure the RF level of a single carrier, such as the control channel, in dBm. Make surethe resolution bandwidth of the spectrum analyzer is 30 kHz. Maximum power in anychannel should not exceed 5W (+37 dB). 4. Calculate the total composite signal power from the EBTS using the following formula: Ptot = Pc + 10Log N where,Ptot is the total composite power in dBmPc is the power per carrier in dBm as measured in step 3, andN is the total number of channels. Note: When two or more HU’s are connected together through the CAN interface, onlyone EMS computer is required to manage the networked Digivance systems. The EMScomputer may be connected to the SERVICE port on any one of the HUs in the network. Note: The optimum level for an 800/900 MHz SMR composite input signal is –20 dBmNote: Check the input rating of the test equipment and the output rating of the EBTS. Toavoid burning out the spectrum analyzer or power meter, it may be necessary to insert a30 dB 100W (or similar) attenuator between the EBTS and test equipment.

Determine the total cable loss that is imposed by the forward path coaxial cable that linksthe EBTS to the HU and also any insertion loss imposed by splitters or combiners. 6. Subtract the total cable loss and any insertion losses from the total composite powercalculated in step 4. 7. Subtract –20 (optimum input signal level) from the value determined in step 6. Thedifference (which should be positive) equals the value of the external attenuator that isrequired to reduce the forward path signal level to the optimum level for input to the HU.The following formula outlines the required calculations for steps 6 and 7: Ptot – (Cable and insertion loss) – (–20) = Value of external attenuator required8. Select an attenuator that is as close to the value calculated in step 7 as possible. 9. Install the external attenuator in the coaxial cable that is connected to the correspondingFORWARD RF IN port at the HU. 10. If turning up an 800/900 MHz SMR system, repeat steps 1–9 for the 935–940 FORWARDRF IN port at the HU. Install the external attenuator in the coaxial cable that is connectedto the 935–940 FORWARD RF IN port at the HU. 11. Subtract the value of the external attenuator from the total composite signal power (Ptot)and record the result. This value will be required when setting the attenuation of the HU’sinternal forward path attenuators. 2.2 Reference Procedure: Enter Site Name and Site NumberAll HU’s and RU’s are programmed with the same site name and site number.

ADCP-75-187 • Issue 3 • September 2006 • Section 3: OPERATIONPage 3-11© 2006, ADC Telecommunications, Inc.2.3 Reference Procedure: Enter Host Forward AttenuationThe HU internal forward path attenuator setting determines the maximum composite outputsignal level at the RU antenna port. The appropriate attenuation value for any particular systemis based on the number of channels the system is transporting and the signal level of thecomposite forward path signals input at the host units RF IN ports. By default, the forward pathattenuator is set to 31 dB. The maximum output power is 38.1 dBm (6.5 Watts) for 800/900 MHz SMR systems, 38.5 dBm(7.0 Watts) for 800 MHz systems, and 37.7 dBm (5.9 Watts) for 1900 MHz systems. The totalforward path gain that is provided by the system (with host and remote forward attenuators set to 0dB) is 78.1 dBm for 800/900 MHz SMR systems, 78.5 dBm for 800 MHz systems, and 77.7 for1900 MHz systems. For 800/900 MHz SMR systems, this procedure sets the attenuation for bothFORWARD RF IN ports. Use the following procedure to set the forward path attenuation to provide the maximumcomposite output signal level: 1. Click on the HOST RF tab. The HOST RF display will open within the EMS mainwindow as shown in Figure 3-7. Figure 3-7. Typical HOST RF Display2. Click on the Host Fwd Att Edit button (see Figure 3-7).

Determine the appropriate value to enter for the Host forward path attenuator bysubtracting the required system output level (per system design plan) from the system gain(78.1 dB for 800/900 MHz SMR, 78.5 for 800 MHz, and 77.7 dB for 1900 MHz) and thenadding the composite input signal level. The result (see sample calculation) is the amountof attenuation required. Atten = (System Gain) – (Required System Output Power) + (Composite Input Power)5. Enter the attenuation value and click OK to close the pop-up screen and to make thechanges take effect. 2.4 Reference Procedure: Determine Output Signal Level at RU Antenna PortThe RF output signal level should be measured at the RU ANTENNA port to verify that thecomposite signal level is at the expected level. Use the following procedure to determine thepower level:1. Place the AC circuit breaker switch (at the RU power panel) in the open (OFF) position. 2. Disconnect the antenna cable from the RU ANTENNA port. 3. Connect a spectrum analyzer or RF power meter to the HU ANTENNA port. (Check theinput rating of the test equipment. Insert a 30 dB 100 W attenuator if necessary.) 4. Place the AC circuit breaker switch (at the RU power panel) in the closed (ON) position.5. If using a spectrum analyzer, proceed to step 6. If using a power meter, measure thecomposite signal power from the RU and then proceed to step 8.6. Measure the RF level of a single carrier, such as the control channel, in dBm. Make surethe resolution bandwidth of the spectrum analyzer is 30 kHz. Note: The RF output signal level measured in this procedure should be approximately31 dBm less than the output level specified for operation. This is because the factorydefault setting for the remote forward attenuator is 31 dB. The final adjustment of thesystem RF output signal level will be completed in Section 2.5

ADCP-75-187 • Issue 3 • September 2006 • Section 3: OPERATIONPage 3-13© 2006, ADC Telecommunications, Inc.7. Calculate the total composite signal power using the following formula: Ptot = Pc + 10Log NWhere,Ptot is the total composite power in dBmPc is the power per carrier in dBm as measured in step 6, andN is the total number of channels. 8. Record the result measured in step 5 or calculated in step 7. 9. Place the AC circuit breaker switch (at the RU power panel) in the open (OFF) position. 10. Disconnect the spectrum analyzer or RF power meter from the HU ANTENNA port. 11. Re-connect the antenna cable to the HU ANTENNA port. 12. Place the AC circuit breaker switch (at the RU power panel) in the closed (ON) position. 2.5 Reference Procedure: Enter Remote Forward AttenuationThe RU internal forward path attenuator setting is used to reduce the power level of thecomposite output signals at the RU. The maximum composite output signal level at the RUantenna port is set using both the HU forward attenuator (see Section 2.3) and the RU forwardattenuator. Component variations may result in the output power at the HU antenna port beingslightly above or below the calculated value. The RU forward attenuator is used in conjunctionwith the HU forward attenuator to add or remove attenuation to produce the required outputsignal level at the antenna port. The default setting for the RU forward attenuator is 31 dB. Usethe following procedure to change the RU forward attenuation: 1. Click on the REMOTE RF tab. The REMOTE RF display will open within the EMS mainwindow as shown in Figure 3-9. 2. Check the level of the RF output signal (as determined in Section 2.4) against the systemdesign plan specifications. The maximum output signal level permitted is 38.1 dBm (6.5Watts) for 800/900 MHz SMR systems, 38.5 dBm (7.0 Watts) for 800 MHz systems, and37.7 dBm (5.9 Watts) for 1900 MHz systems. 3. Determine if more or less attenuation is required to produce the required output signal level. 4. Click on the Remote Fwd Att field Edit button (see Figure 3-9). The Remote Fwd Attpop-up screen will open as shown in Figure 3-10. Note: To comply with Maximum Permissible Exposure (MPE) requirements, themaximum composite output from the antenna cannot exceed 1000 Watts EIRP and theantenna must be permanently installed in a fixed location that provides at least 6 meters(20 feet) of separation from all persons.Caution: The RU may be destroyed if the maximum recommended output signal level at the RUantenna port is exceeded. Make sure that sufficient attenuation is inserted in the forward path toprevent the RU from being overdriven.

To interface with the EBTS,the reverse path signal level must be adjusted to provide the signal level required at the EBTSinput port(s). The HU provides from –1 to +30 dB of gain in the reverse path. By default, thehost reverse attenuator is set to –31 dB of attenuation which provides –1 dB of gain. Use thefollowing procedure to set the reverse path gain:1. Check the EBTS manufacturer’s specifications to determine the composite signal levelrequired at the reverse path input port(s). Note that 800/900 MHz SMR host units have tworeverse path input ports. 2. Determine the overall gain and loss imposed on the signal by the antenna, antenna cable,and by the cables that connect the HU to the EBTS. 3. Determine the amount of gain required to raise the reverse path signal to the level requiredat the EBTS. 4. Click on the HOST RF tab.

The Digivancesystem requires minimal regular maintenance to insure continuous and satisfactory operation.The only components that require regular replacement are the HU cooling fans.Maintenance also includes diagnosing and correcting service problems as they occur. When analarm is reported, it will be necessary to follow a systematic troubleshooting procedure to locatethe problem. Once the source of the problem is isolated, the appropriate corrective action can betaken to restore service. The only internal components that can be replaced are the cooling fansthat mount in the HU. The failure of any other internal component will require replacement ofthe entire unit. 1.1 Tools and MaterialsThe following tools and materials are required in order to complete the maintenance proceduresspecified in this section: • IR filtering safety glasses• Patch cords with SC connectors• 15 dB in-line SC optical attenuators• Optical power meter (1550 and 1310 nm)Content Page

ADCP-75-187 • Issue 3 • September 2006 • Section 4: MAINTENANCEPage 4-2© 2006, ADC Telecommunications, Inc.2 FAULT DETECTION AND ALARM REPORTINGThe Digivance LRCS on-board embedded software detects various unit and system faults whichgenerate either a Major or Minor alarm. A Major alarm indicates that the system has failed in away that directly affects RF transport performance. When a major alarm occurs, all RFfunctions are disabled and the system is out of service. A Minor alarm means that systemperformance is not affected or in some cases, that the performance may no longer be optimal.When a minor alarm occurs, RF functions continue and the system remains in service. The following means are used to report Major and Minor alarms: • HU alarm contacts• HU and RU LED’s• EMS software Graphical User Interface (GUI)• Network Operations Center - Network Element Manager (NOC/NEM) interface• SNMP interfaceThe HU is equipped with a set of both normally open (NO) and normally closed (NC) alarmcontacts which may be used to report both Major and Minor alarms to an external alarm system.The alarm contacts summarize the inputs so that any Major or Minor alarm will trigger an alarmreport to the external alarm system. The HU is equipped with multiple front panel LED indicators that show status and alarminformation by displaying various colors: Green, Red, Yellow, and Off. The RU is equippedwith a single LED indicator that shows status and alarm information by displaying either Red orOff. A detailed description of the Host Unit and Remote Unit LED indicators is providedrespectively in Table 4-1 and Table 4-2. The EMS software GUI provides both a summary and a detailed list of alarm information thatincludes unit and module level faults, circuit faults, and measured value faults such as voltages,RF power, and temperature. A summary showing a list of all systems and their current alarmstatus is presented through the Alarm OverView display. A more detailed list of alarminformation is presented through the HOST alarm display and the REMOTE alarm display. Thevarious fault conditions that trigger a major or minor alarm report are shown in the HOST andREMOTE alarm displays. The NOC/NEM interface provides the same summary and detailed listing of alarm informationas the EMS software GUI but in an ASCII text string format. Sending the command GETALARMSUMMARY produces a list of all systems and their current alarm status. Sending thecommand GET ALARM ALL for a specific system will produce a detailed list of alarminformation for the specified system. The SNMP interface provides alarm information to up to ten SNMP managers which must beregistered with the SNMP agent. The SNMP interface allows the SNMP managers to receive thealarm and status information generated by the host and remote units. The presentation of thealarm information is dependent on the features of the SNMP manager.

ADCP-75-187 • Issue 3 • September 2006 • Section 4: MAINTENANCEPage 4-4© 2006, ADC Telecommunications, Inc.3 FAULT ISOLATION AND TROUBLESHOOTINGAlarm information may be accessed using the HU and RU LED indicators, the EMS softwareGUI, the NOC-NEM interface, or the SNMP manager. When an alarm occurs, use the unit LEDindicator(s) and any one of the specified software tools to determine which Digivance system isaffected, which unit (HU or RU) reported the alarm, and the fault that generated the alarm. Thenrefer to either Section 3.1 Host Unit Troubleshooting or Section 3.2 RU Troubleshooting toisolate the problem and to determine the corrective action required. When attempting to isolate a problem, always determine the initial fault that generated thealarm report. Some faults may cause additional faults to be reported which tends to obscure theinitial reason for the alarm. To help isolate faults, the EMS GUI provides an AlarmOverviewscreen, shown in Figure 4-1, that indicates which Digivance system/unit is reporting the alarm.Figure 4-1. AlarmOverView Screen The AlarmOverview screen includes an ALARM HIST indicator which the user should click toacknowledge that an alarm exists. Acknowledging the alarm opens the Alarm History Infodialog box (also shown in Figure 4-1) which directs the user to view the EMS Log file fordetails. The EMS Log file lists the various faults in the order in which they occurred. Clear eachfault starting with the initial fault. In most instances, clearing the initial fault will also clear anyremaining faults. For additional information on using the AlarmOverview screen, refer to theDigivance Element Management System User Manual (see Related Publications section).Note: It is recommended that if there are alarms at both the HU and RU, the optical faultsshould be checked and cleared first. Because the HU and RU function as a system, a faultin the fiber optic link will cause alarms to be reported by both the HU and RU.

ADCP-75-187 • Issue 3 • September 2006 • Section 4: MAINTENANCEPage 4-11© 2006, ADC Telecommunications, Inc.4 TEST PROCEDURESThis section provides procedures for common troubleshooting and maintenance tests. Refer tothese procedures as needed when specified in the Fault/Alarm Isolation Diagrams in Section 3. 4.1 Optical Power TestA break in an optical fiber or a fault with the optical connector will interrupt communicationsbetween linked components or generate excessive errors. Use the following procedure to isolatea problem with an optical fiber or connector. 1. Put on the IR filtering safety glasses. 2. Notify the NOC or alarm monitoring system operator that the system is going offline. 3. At the HU, place the On/Off switch in the OFF position (press O). At the RU, place theAC circuit breaker switch in the open (OFF) position. 4. Disconnect the optical fiber connectors for the fiber to be tested at the HU and the RU. 5. Inspect the optical connectors. Verify that connectors are clean and that no scratches orimperfections are visible on the fiber end. Clean and polish the optical connectors if necessary. 6. Connect the optical power meter to the output (receiver) end of the optical fiber as shownin Figure 4-2. If an attenuator was included in the fiber link, make sure it is installed. Figure 4-2. Forward and Reverse Path Optical Fiber Test Set UpDanger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do notlook directly into the optical transmitter of any unit or exposure to laser radiation may result.An optical power meter should be used to verify active fibers. A protective cap or hood MUSTbe immediately placed over any radiating transmitter or optical fiber connector to avoid thepotential of dangerous amounts of radiation exposure. This practice also prevents dirt particlesfrom entering the connector.Note: Turning off the HU and RU disables the respective lasers which is necessary inorder to safely inspect and clean the optical connectors.

Connect the input (transmitter) end of the optical fiber to the transmitting HU or RU. 8. If the transmitting unit is the HU, place the On/Off switch in the ON position (press I). Ifthe transmitting unit is the RU, close (turn on) the AC circuit breaker switch. 9. Using the transmitting HU or RU as an optical light source, measure the optical power atthe receiver end of the optical fiber. The power level of the optical signal received at theHU or RU should be –15 to –25 dBm (with attenuator installed). If the power level of thereceived optical signal is within this range, the optical fiber and the far end unit are good.If the power level of the signal is greater than –15 dBm, insert additional attenuation tobring the signal level within the specified range. If the power level is less than –25 dBm,the value of the external attenuator is too high, the optical fiber is faulty, or the far end unitoptical transmitter is faulty. Continue with test procedure to isolate the problem 10. If the transmitting unit is the HU, place the On/Off switch in the OFF position (press O).If the transmitting unit is the RU, open (turn off) the AC circuit breaker switch. 11. Disconnect the optical power meter from the receiver end of the optical fiber.12. Use a 1 meter patch cord to connect the optical power meter to the transmitting HU orRU as shown in Figure 4-3.Figure 4-3. Host Unit and Remote Unit Optical Transmitter Test Set Up13. If the transmitting unit is the HU, place the On/Off switch in the ON position (press I). Ifthe transmitting unit is the RU, close (turn on) the AC circuit breaker switch. 14. Measure the optical output power of the transmitting HU or RU. The power level of theoptical output signal from the HU or RU must meet the following specification: Forward Path Signal at the HU: 0 + 1 dBmReverse Path Signal at the RU: +1.3 + 1 dBmIf the power level of the optical output signal is within specifications with a 1 meter patchcord installed, the fiber optic link is faulty. If the power level of the optical signal is notwithin specifications, the far end HU or RU optical transmitter is faulty.Caution: Erratic operation may occur with an optical input signal level of –13 dBm or higher.If the optical input signal level exceeds –9 dBm, the optical receiver may be damaged.

If the transmitting unit is the HU, place the On/Off switch in the OFF position (press O).If the transmitting unit is the RU, open (turn off) the AC circuit breaker switch. 16. Disconnect the optical power meter from the receiver end of the optical fiber.17. Reconnect the optical fibers to the receiving HU or RU. 18. Repeat steps 3 through 17 for each optical fiber that requires testing. 19. When ready to put the system back into service, place the On/Off switch on the HU in theON position (press I) and close (turn on) the AC circuit breaker switch for the RU. 20. Notify the NOC or alarm monitoring service that the system is going back online. 4.2 Optical Loopback TestThe following procedure provides a test to determine if an optical port fault exists with the HostUnit. 1. Put on the IR filtering safety glasses. 2. Notify the NOC or alarm monitoring system operator that the system is going offline. 3. Place the On/Off switch in the OFF position (press O).4. Disconnect the optical fiber connectors from the FWD (PORT 1) and REV (PORT 2)optical ports and place a dust cap over each connector. 5. Plug a 15 dB in-line optical attenuator into the FWD (PORT 1) optical port as shown inFigure 4-4. 6. Connect a 1 meter patch cord between the optical attenuator and the REV (PORT 2)optical port. 7. Place the On/Off switch in the ON position (press I). Note: Because the RU is equipped with a WDM, the optical loopback test cannot beperformed on the RU. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do notlook directly into the optical transmitter of any unit or exposure to laser radiation may result.An optical power meter should be used to verify active fibers. A protective cap or hood MUSTbe immediately placed over any radiating transmitter or optical fiber connector to avoid thepotential of dangerous amounts of radiation exposure. This practice also prevents dirt particlesfrom entering the connector. Caution: The optical receiver can be damaged if the power level of the optical input signal istoo high. To avoid damaging the optical receiver when performing the loopback test, alwaysinstall a 15 dB in-line attenuator in the optical receiver circuit.
