System Configuration
The UNIVERGE
NEAX
IPS
DMR
consists of from one to two MODULAR CHASSIS depending
on the system configuration. There are 2 types of MODULAR CHASSIS; "Physical Modular
Chassis" and "Virtual Modular Chassis ".
The Physical Modular Chassis is “hardware Modular Chassis” and is used to accommodate an
MP, FPs, IP PADs, legacy LT/AP cards, and power supply units. The Physical Modular Chassis
provides 56 LT ports in hardware slots and provides 8 ports in software port allocation (56 LT
ports and 8 virtual ports). One Modular Chassis provides 8 card slots including one card slot for
Main Processor (MP) and other 7 slots for Line Trunk (LT)/Application Processor (AP) cards; 56
LT ports and 8 virtual LT ports; AC, LTC, BUS cable connectors and power switch which are
located at the rear side of Modular Chassis. The Physical Modular Chassis can be installed on
the desktop or into the 19-inch rack only.
The Virtual Modular Chassis is a “software Modular Chassis” with a port capacity of 64 ports. A
maximum of two Virtual Modular Chassis can be assigned per IPS
DMR
for a total of 128 ports
used to accommodate IP stations by system data programming.
The UNIVERGE
NEAX
IPS
DMR
locates the maximum of 64 FP/AP cards per system, at multiple
Remote Sites. The number of FP/AP cards accommodated at one Remote Site should be a
maximum of eight including the MP built-in FP. If more than eight FP/APs are assigned, the
system does not operate normally. The maximum number of Remote Sites is 30. The MP card at
Remote Site has the same system data as that at Main Site, because Remote Site automatically
gets the data from Main Site at the time of setup. In normal operation, Main Site automatically
copies the system data to Remote Site through the network once a day. Because the CP31-D is a
cost down CPU, the following options that are built-in on the CP24 are not available with the
CP31:
•
No built-in DAT.
•
Only one RS Port.
•
No built-in DK (external/relay key).
•
No MN Alarm Indication
