Hardware architecture

The legacy Nortel ISP1100 Signalling Server can still be used.

CS 1000 Release 5.0 introduces three new servers that can host a CS
1000 Release 5.0 Signaling Server:

"Nortel Common Processor Pentium Mobile server" (page 51)

"International Business Machines X306m server" (page 52)

"Hewlett Packard DL320-G4 server" (page 52)

The Signaling Server has both an ELAN and TLAN network interface. The
Signaling Server communicates with the Call Server through an ELAN
subnet.

The Signaling Server is mounted in a 19-inch rack. The Signaling Server
can be installed in a load-sharing redundant configuration for higher
scalability and reliability.

The following software components operate on the Signaling Server:

"Terminal Proxy Server" (page 53)

(TPS)

"SIP/H.323 Signaling Gateways" (page 53)

"Network Routing Service" (page 53)

(NRS)

"Element Manager" (page 55)

Application Server

All the software elements can coexist on one Signaling Server or reside
individually on separate Signaling Servers, depending on traffic and
redundancy requirements for each element.

For more information about H.323 and SIP Trunking, refer to IP Peer
Networking Installation and Commissioning (NN43001-313)

Nortel Common Processor Pentium Mobile server

The Nortel Common Processor Pentium Mobile (CP PM) server is a
high-performance, circuit card-based server that can be configured as a Call
Server or a Signaling Server in a CS 1000 Release 5.0 system. The CP
PM NTDW66 model can be configured as a Signaling Server and installed
in a Universal Equipment Module (UEM) in a CS 1000M SG or CS 1000M
MG system.

The Nortel CP PM Signaling Server delivers capacity improvement by
providing flexible scaling from 0 to 22,000 IP Phones and a 70% increase
in power for Signaling Server applications. The increased application
power and capacity, coupled with the reduction in foot print and power
consumption, means a lower cost of ownership.
