Nortel Networks NN43021-110 manual Terminal Proxy Server, SIP/H.323 Signaling Gateways

52System architecture

The HP DL320-G4 1U server has the following components:

•Intel Pentium 4 processor (3.6 GHz)

•Two 80 GB SATA Hard drives (1 configured)

•4 GB PC2-4200 ECC DDR2 SDRAM (2 GB configured

•Two 10/100/1000BaseT Ethernet ports

•One CD-R/DVD ROM drive

•One serial port

•Three USB ports

•For more information about installing and configuring the HP DL320-G4 server as a Signaling Server, see Signaling Server Installation and Commissioning (NN43001-312), .

Terminal Proxy Server

The Terminal Proxy Server (TPS) acts as a signaling gateway between the IP Phones and the Call Server using the UNIStim protocol. It performs the following functions:

•converts the IP Phone UNIStim messages into messages the Call Server can interpret

•allows IP Phones to access telephony features provided by the Call Server

The TPS also controls IP Phone registration.

SIP/H.323 Signaling Gateways

SIP/H.323 Signaling Gateways are software components configured on virtual loops, similar to IP Phones. They bridge existing call processing features and the IP network. They also enable access to the routing and features in the MCDN feature set.

Note 1: The SIP/H.323 Signaling Gateway must register with the Network Routing Service (NRS).

Note 2: Virtual TNs enable you to configure service data without hardwiring IP Phones to the CS 1000M system. Virtual TNs are configured in LD 97.

To support IP Peer Networking, dual Call Servers in a CS 1000M must be associated with Signaling Servers that run SIP/H.323 Signaling Gateway software. The number of Signaling Servers required depends on the capacity and level of redundancy required.
