CHAPTER 2 SYSTEM CONFIGURATIONUNIVERGE NEAX 2000 IPS General Description Page 41Issue 5UNIVERGE NEAX ® IPSDMR System ConfigurationThe UNIVERGE NEAX IPS DMR consists of from one to two MODULAR CHASSIS dependingon the system configuration. There are 2 types of MODULAR CHASSIS; "Physical ModularChassis" and "Virtual Modular Chassis ".The Physical Modular Chassis is “hardware Modular Chassis” and is used to accommodate anMP, FPs, IP PADs, legacy LT/AP cards, and power supply units. The Physical Modular Chassisprovides 56 LT ports in hardware slots and provides 8 ports in software port allocation (56 LTports and 8 virtual ports). One Modular Chassis provides 8 card slots including one card slot forMain Processor (MP) and other 7 slots for Line Trunk (LT)/Application Processor (AP) cards; 56LT ports and 8 virtual LT ports; AC, LTC, BUS cable connectors and power switch which arelocated at the rear side of Modular Chassis. The Physical Modular Chassis can be installed onthe desktop or into the 19-inch rack only.The Virtual Modular Chassis is a “software Modular Chassis” with a port capacity of 64 ports. Amaximum of two Virtual Modular Chassis can be assigned per IPS DMR for a total of 128 portsused to accommodate IP stations by system data programming.The UNIVERGE NEAX IPS DMR locates the maximum of 64 FP/AP cards per system, at multipleRemote Sites. The number of FP/AP cards accommodated at one Remote Site should be amaximum of eight including the MP built-in FP. If more than eight FP/APs are assigned, thesystem does not operate normally. The maximum number of Remote Sites is 30. The MP card atRemote Site has the same system data as that at Main Site, because Remote Site automaticallygets the data from Main Site at the time of setup. In normal operation, Main Site automaticallycopies the system data to Remote Site through the network once a day. Because the CP31-D is acost down CPU, the following options that are built-in on the CP24 are not available with theCP31:• No built-in DAT.• Only one RS Port.• No built-in DK (external/relay key).• No MN Alarm Indication
