Nortel Networks COMMUNICATION SERVER 1000 NN43021-110 - Manual (Page 50)

50 System architecture
CS 1000 Release 5.5 introduces three new servers that can host a CS
1000 Release 5.5 Signaling Server:
• “Nortel Common Processor Pentium Mobile server” (page 50)
• “International Business Machines X306m server” (page 51)
•
“Hewlett Packard DL320-G4 server” (page 51)
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 52) (TPS)
• “SIP/H.323 Signaling Gateways” (page 52)
• “Network Routing Service” (page 53) (NRS)
•
“Element Manager” (page 55)
• Application Server
Signaling Server 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 any co-resident Signaling
Server software element combination the maximum call rate supported
is 10K cph.
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 5.5 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.
