ADCP-75-126 • Issue B • April 2002 • Section 2: DescriptionPage 2-21©2002, ADC Telecommunications, Inc.6.4 EMS Software User InterfaceThe EMS software provides two user interfaces: the Graphical User Interface (GUI) and theNetwork Operation Center-Network Element Manager (NOC/NEM) interface. Both interfacesprovide essentially the same functionality except only the GUI can upgrade the LRCS systemwith new system software. In addition, only the NOC/NEM interface can record and playbackalarm data.The GUI is presented at the EMS computer or on alaptop computer. The GUI is used for localcontrol and monitoring operations. The GUI consists of aseries of displays and screens, such asthe one shown in Figure 2-10,that provide the user with alarm and status information and thatallow the user to set various operating parameters.Figure 2-10. EMS Graphical User Interface Host/Remote DisplayThe NOC/NEM interface is acommand line interface that is presented at an NOC terminal. TheNOC/NEM interface is used for remote control and monitoring operations. The NOC/NEMinterface consists of ASCII text strings that are input as SET or GET commands which arefollowed by the action or information required. Atext string response is received from thespecified LRCS system or systems to confirm the requested action or to report the requestedinformation. Examples of several typical NOC-NEM interface commands and the responsesreceived are shown in Figure 2-11.The NOC/NEM interface requires only aVT100 terminal/emulator or aPC-type computer that is loaded with acommunication software such asProcomm Plus. While primarily intended for use at the NOC, the NOC/NEM interfacecommands may also be input from the EMS computer.

Use the followingprocedure to unpack and inspect the HU and any accessories:1. Open the shipping cartons and carefully unpack each component from the protectivepacking material.2. Check each component for broken or missing parts. If there are damages, contact ADC(see section 6at the end of this manual) for an RMA (Return Material Authorization) andto reorder if replacement is required.2 OSP FIBER CABLE INSTALLATION GUIDELINESThe outside plant (OSP) fiber optic cables should be routed between the HU and RU andterminated before the equipment is installed. Adiagram of atypical OSP cable routing is shownin Figure 3-1.At the HU, the OSP cable should be terminated at afiber distribution panel andspliced to pigtails. Jumper patch cords may then be used to link the HU optical ports to the OSPcable terminations. Whenever possible, aguideway such as the FiberGuide system should beprovided to protect the fiber optic patch cords from damage and to prevent excessive bending.The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 7.
ADCP-75-126 • Issue B • April 2002 • Section 3: Host Unit InstallationPage 3-3©2002, ADC Telecommunications, Inc.Figure 3-1. Typical OSP Cable RoutingAt the RU, the OSP fiber optic cable should be spliced to aconnectorized outdoor-rated cable(consisting of individual jacketed pigtails) which is routed into the RU cabinet. The individualpigtails can then be connected directly to the STM optical ports. Aconnector is provided on thebottom of the RU cabinet to seal the cable entry point and provide strain relief. The procedurefor routing the fiber cable into the RU cabinet and for connecting the pigtail leads to the STM isprovided in the Digivance LRCS Single Band SMR Remote Unit Installation Instructions(ADCP-75-122).When all splices and terminations are completed, test each fiber for optical loss as described inSection 5 of this document. The optical loss budget for 9/125, single-mode fiber is 25 dBminimum for an optical BER of 10-6.The power level of the received optical signal should notexceed –15 dBm to avoid overdriving the optical receiver. If necessary, use an in-line opticalattenuator to adjust the signal level.HOST UNITFIBER DISTRIBUTION PANELXXSTMREMOTE SITEHOST SITEPATCHCORDSPLICEPIGTAILSPLICEENCLOSUREINDOOR/OUTDOORCABLE WITH PIGTAIL LEADSOUTSIDE PLANTCABLEREMOTE UNITCABINET16889-A

If the application does not require the use of aWDM, skip this section and proceed to Section 4.The version of the WDM that is used with the HU consists of one or two WDM modules and aWDM mounting shelf. Each WDM module can support two HU’s and each WDM mountingshelf can hold two WDM modules. Afully loaded WDM mounting shelf can therefore supportfour HU’s.When multiple HU’s require connection to aWDM, the WDM mounting shelf and the HU’sshould be mounted in the equipment rack as shown in Figure 3-2.This configuration allows thepigtail leads from the two WDM modules to be connected directly to the optical ports on anyone of the four HU’s.Figure 3-2. Typical WDM and HU ConfigurationThe WDM mounting shelf may be mounted in either a19-inch or 23-inch EIA or WECOequipment rack. Four #12-24 screws are provided for securing the mounting shelf to the rack.Use the following procedure to install the WDM mounting shelf in the equipment rack and tomount the WDM modules in the WDM mounting shelf:1. The WDM mounting shelf is shipped with the mounting brackets installed for 19-inch EIArack installations. If installing the mounting shelf in a19-inch EIA rack, proceed to step 5.If installing the mounting shelf in a19-inch WECO rack, a23-inch EIA rack, or a23-inchWECO rack, proceed to step 2.WDM MOUNTINGSHELF(WITHOUT MODULES)16886-APOWERWORXFUSE PANELHOST UNITS
