communication failure occurs between the Main Site and Remote Site, the Remote Site
automatically changes over to a survival mode and operates as a stand-alone system.

The NEAX IPS-DMR is designed primarily for distributed IP networking but also supports
traditional analog and digital trunks for connection to the Public Switched Telephone Network
(PSTN). The NEAX IPS-DMR supports up to 128 peer-to-peer IP stations and 40 TDM ports in
a single modular chassis. Up to two chassis can be stacked providing maximum capacity of 80
TDM ports while still supporting as many as 128 peer-to-peer IP stations.
Note: The MP card at Remote Site has the same system data as the CPU at the Host Site; the Host
Site automatically downloads system data to the Remote Site at the time of setup. In normal operation,
Main Site automatically downloads a copy the system data to Remote Site through the network once a
day.
Because the CP31 is designed as a Remote PIM CPU, the following options that are built-in on
the CP24 are not available with the CP31:
No built-in modem.
No built-in DAT.
Only one RS Port.
No built-in DK (external/relay key).
No MN Alarm Indication
