Chapter 13 Voice Over IP (VoIP)

Remote PIM over IP

Remote PIM over IP targets users who have 1-30 relatively small offices that accommodate

10-30 extensions at the Remote Site. When UNIVERGE NEAX IPS DMR or UNIVERGE NEAX 2000 IPS PIM are installed at remote site, and connected to an IPS or IPS DM at main site over IP network, the Main Site system controls and maintains the Remote PIM operation as one single system. If a 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.

UNIVERGE NEAX IPS DMR: IPS Distributed Model Remote (with CP31-A/C)

UNIVERGE NEAX 2000 IPS: IPS PIMMK (with CP24-A/B/C)

The UNIVERGE 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 UNIVERGE NEAX IPS DMR supports up to 128 peer-to-peer IP stations and 56 TDM ports in a single modular chassis. Up to two chassis can be stacked providing maximum capacity of 112 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 as a DMR 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
