ADCP-75-187 • Issue 1 • September 2005 • PrefacePage viii© 2005, ADC Telecommunications, Inc.GENERAL SAFETY PRECAUTIONSSTANDARDS CERTIFICATIONFCC: This equipment complies with the applicable sections of Title 47 CFR Part 90.Installation requirements the licensee needs to follow are listed in Title 47 CFR 90.635. Thisdocument may be found at the following website: http://www.access.gpo.gov/nara/cfr/waisidx_03/47cfr90_03.html. Danger: 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. Fiber optic patch cords or pigtails may be permanently damaged if bentor curved to a radius of less than 2 inches (50 mm).

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 1 • September 2005 • Section 1: OVERVIEWPage 1-3© 2005, 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 both 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 1 • September 2005 • Section 1: OVERVIEWPage 1-7© 2005, 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 1 • September 2005 • Section 1: OVERVIEWPage 1-8© 2005, 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 so 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 elementmanager system (EMS). Figure 1-9 shows a typical SCS system equipped with a dual-band RU.One fiber is used to transport the forward/reverse path optical signals for one SCS system. Theother fiber is used to transport the forward/reverse path optical signals for the other SCS system.

ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-2© 2005, ADC Telecommunications, Inc.1 INTRODUCTIONThis section describes the basic components of a typical Digivance 800/900 MHz SMR SCSsystem including the Host Unit (HU), Remote Unit (RU), element management system, andaccessories. The system specifications are provided in a table at the end of this section. 2 HOST UNITThe HU, shown in Figure 2-1, provides 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 RF connectors, optical connectors,alarm output connectors, DC power terminal strip, and grounding lug are mounted on the HUrear panel. The On/Off power switch, LED indicators, service interface connector, andController Area Network (CAN) connectors are mounted on the HU front panel. 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 installed, the front panel of the HU is flush with the front of the rack.Screws are provided for securing the HU to the equipment rack.
ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-3© 2005, ADC Telecommunications, Inc.Figure 2-1. Host Unit2.3 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. 2.4 RF Signal ConnectionsThe RF signal connections between the HU and the EBTS are supported through four N-typefemale connectors. Two connectors are used for the forward path RF signals. The other twoconnectors are used for the reverse path RF signals. In most installations, it is usually necessaryto install external attenuators to support the RF interface between the HU and the EBTS. TheHU should be as close as possible to the EBTS to minimize coaxial cable losses. 17.1 INCHES(433 mm)3.5 INCHES(88 mm)12.2 INCHES(311 mm)FRONT PANELMOUNTINGBRACKET(BOTH SIDES)20020-A
ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-4© 2005, ADC Telecommunications, Inc.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. 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. Note: The optimum composite RF input signal level is –20 dBm.

ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-8© 2005, ADC Telecommunications, Inc.Figure 2-3. Interim Single-Band Remote Unit3.2 MountingThe RU may be mounted on a flat vertical surface (such as the side of a building) or on a utilitypole. A combination wall/pole mounting bracket is provided with each unit. A separate strand-mount kit (accessory item) is available if it is necessary to mount the RU from a cable. Agrounding lug is provided on the bottom of the RU enclosure for connecting a grounding wire. 3.3 Fault Detection and Alarm ReportingThe RU detects and reports various faults including remote unit fault, optical fault, output powerfault, temperature fault, and power amplifier fault. A single bottom-mounted Light EmittingDiode (LED) indicator turns from off to red if a major fault is detected. The status of the STMand LPA, the alarm state, and other fault information is summarized and reported over theoptical interface to the HU. Fault and alarm information may be accessed at the HU through theEMS software GUI or remotely through the NOC/NEM interface or SNMP interface. 3.4 Antenna Cable ConnectionThe antenna cable connection between the RU and the antenna is supported through a single N-type female connector. The N-type connector provides a connection point for the antenna cable.The forward and reverse path RF signals are combined on the same antenna cable. It isrecommended that a lightning protector (accessory item) be connected to the antenna port priorto connecting the antenna cable. On an optional basis, the dual-band RU (future) may beequipped with two N-type connectors to support antenna connections to two separate antennas. 20568-C
ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-9© 2005, ADC Telecommunications, Inc.3.5 RF Signal Level AdjustmentThe RU is equipped with digital attenuators for adjusting the signal level of the forward path RFoutput signals. The remote forward path attenuators adjust the level of the two output RFsignals at the RU antenna port and will add from 0 to 31 dB of attenuation to the output signallevel. The attenuator can be set in 1 dB increments. The attenuator is software controlled and isadjusted through the EMS software GUI, the NOC/NEM interface, or SNMP interface. 3.6 Optical ConnectionFiber optic connections between the single-band RU and the associated HU are supportedthrough one OptiTap hardened optical connector port. All single-band RU’s are equipped withan internally mounted Wavelength Division Multiplexer (WDM). This allows a single opticalport to provide the optical fiber connection for the combined forward and reverse path signals. Fiber optic connections between the dual-band RU and the two associated HU’s (two HU’s arerequired with a dual-band RU) are supported through two OptiTap hardened optical connectorports. All dual-band RU’s are equipped with two internally-mounted WDM’s. One portprovides the optical fiber connection for the combined forward and reverse path signals for HU#1. The other port provides the optical fiber connection for the combined forward and reversepath signals for HU #2. An APC/SC (angled) connector and adapter is mounted within each OptiTap optical port. Dropcables terminated with OptiTap connectors are available separately. The stub end of each dropcable must be routed to an external splice enclosure (not provided) for splicing to the OutsidePlant (OSP) fiber optic cable. 3.7 PoweringThe 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. The power issupplied through a three-wire AC power cable that is provided with the RU. The power cableconnects to a mini 3-pin power connector mounted on the bottom of the RU enclosure. The stubend of the cable must be hard-wired to the AC power source. The cable is UL and NationalElectrical Code (NEC) approved for continuous outdoor exposure without conduit. 3.8 CoolingPassive cooling of the electronic assemblies is provided by conducting excess heat from theelectronic components to the aluminum enclosure. The heat is then dissipated to the outside airby radiation and convection air flow over the enclosure’s external cooling fins. An alarm isgenerated if a high temperature condition occurs within the enclosure. If necessary, the RU maybe equipped with solar shields (accessory) that reduce the effect of solar loading on thealuminum enclosure.

ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-13© 2005, ADC Telecommunications, Inc.5.2 Software InstallationSoftware installation consists of inserting each software 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 software files in assigned folders on thecomputer’s hard drive. Software installation instructions are provided in the Digivance ElementManagement System User Manual (ADCP-75-182). 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 (ADCP-75-182). 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. If multiple HUs are networked together using the CAN interface, allunits may be managed by connecting the EMS computer to the service connector on any one ofthe networked HUs. 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 aT1 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.
ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-14© 2005, ADC Telecommunications, Inc.5.5 Digivance EMS User InterfacesThe Digivance EMS provides three user interfaces: the EMS Graphical User Interface (GUI),the Network Operation Center–Network Element Manager (NOC/NEM) interface, and theSNMP GUI interface. The EMS GUI, the NOC interface, and the SNMP GUI provide the samebasic functions. However, the NOC interface and the SNMP GUI cannot be used to downloadnew system software to the Digivance system. In addition, the SNMP GUI cannot be used toassign 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 2-6, 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(ADCP-75-182) for additional information. Figure 2-6. Graphical User Interface Host/Remote DisplayThe 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 2-7. 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(ADCP-75-182) for additional information.
ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTIONPage 2-15© 2005, ADC Telecommunications, Inc.Figure 2-7. NOC/NEM Interface Typical CommandsThe SNMP interface is a GUI that is used for remote control and monitoring operations (exceptsoftware download 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 LRCS SNMP agent. Other SNMP managers are available from various networkmanagement software venders. Refer to the SNMP Agent Software User Manual (ADCP-75-183) for additional information. 6 SPECIFICATIONSRefer to the following tables for the system, host unit, and remote unit specifications.

For situations where multiple carrier signals are present, the rating would haveto be reduced by 3.5 dB, especially where the output signal is re-radiated and can causeinterference to adjacent band users. This power reduction is to be by means of input power orgain reduction and not by an attenuator at the output of the device.
