Two types ofpanels are available: the Conditioning Panel and the Duplexing Panel. The Conditioning Panel,shown in Figure 2-11,provides attenuation of the forward path signal to the level required forinput to the HU. The Conditioning Panel also provides forward and reverse path combining andsplitting (as needed) to enable multi-BTS to single HU, multi-BTS to multi-HU, or single BTSto multi-HU configurations.Figure 2-11. Conditioning PanelThe Duplexing Panel, shown in Figure 2-12,is used in conjunction with the Conditioning Panelwhen the BTS provides aduplexed forward and reverse path RF connection. The DuplexingPanel separates the duplexed forward and reverse path signals. This allows the BTS to beconnected to the HU which has separate forward and reverse path RF ports. For completeinformation about the Conditioning Panel and Duplexing Panel, refer to the Digivance RFTransport Solution 800 and 1900 MHz Interface Panels User Manual (ADCP-75-144).Figure 2-12.

ADCP-75-150 • Preliminary Issue A • March 2003 • Section 2: DescriptionPage 2-25©2003, ADC Telecommunications, Inc.10 DIGIVANCE ELEMENT MANAGEMENT SYSTEMThe Digivance Element Management System (DEMS) is anetwork management tool thatprovides control and monitoring functions for the Digivance system. The DEMS is used toprovision and configure new systems for operation, set system operating parameters, get systemalarm and status messages, and upgrade the system software. The DEMS supports both localcontrol by an on-site service technician and remote control by aNetwork Operations Center(NOC).10.1 Primary ComponentsThe DEMS, shown in Figure 2-17,consists of aPC-type desk-top computer (not provided) thatis loaded with the DEMS software. The DEMS software is stored on aCD-ROM that is shippedwith the HU. The DEMS software must be installed on the DEMS computer along with the Java2Version 1.3.1 Runtime Environment software which is also provided. Installation consists ofinserting the CD-ROM into the computer’s CD-ROM drive and then running the software installprograms. This places the Java 2Runtime Environment and DEMS software files in assignedfolders on the computer’s hard drive.Figure 2-17. Alarm Network UnitThe DEMS software may also be installed on aPC-type lap-top computer (not provided). Alap-top version of the DEMS computer can be used as aportable network management tool forservice and maintenance purposes. Alaptop DEMS computer can be connected temporarily to asystem to enter the initial configuration data or to trouble-shoot problems and then removedwhen the task is completed. Permanent control and monitoring functions would be provided bythe desk-top DEMS computer.CD-ROM WITH EMSSOFTWAREORPLUS16803-A
ADCP-75-150 • Preliminary Issue A • March 2003 • Section 2: DescriptionPage 2-26©2003, ADC Telecommunications, Inc.10.2 Service Interface ConnectionThe service interface connection between the DEMS computer and the HU or RU requires thatthe DEMS computer be equipped with aDB-9 connector that is configured to provide an RS-232 DCE interface. Astraight-through RS-232 interface cable (accessory item) equipped with amale DB-9 connector on one end and aPC-compatible connector on the other end is required tolink the DEMS computer to the HU. When multiple HUs are networked together, the DEMScomputer may be connected to the service connector on any one of the networked HUs.10.3 NOC Interface ConnectionThe NOC interface connection between the DEMS computer and the NOC requires that theDEMS computer be equipped with aconnector that is configured to provide an RS-232 ASCIIinterface. The link between the DEMS computer and the NOC would generally be supported byadata network. Cables and equipment (not provided) to support the RS-232 interfaceconnection between the DEMS computer and the data network or dial-up modem are required.10.4 DEMS Software User InterfaceThe DEMS 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 Digivancesystem with new system software. In addition, only the NOC/NEM interface can record andplayback alarm data.The GUI is presented at the DEMS 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 2-18,that provide the user with alarm and status information and thatallow the user to set various operating parameters.Figure 2-18.
