Communication Server 1000S Overview

Signaling Server

CS 1000S systems use a Signaling Server. The Signaling Server is an

industry-standard, PC-based server that provides a central processor to drive

H.323 and Session Initiation Protocol (SIP) signaling for IP Phones and

IP Peer Networking. It provides signaling interfaces to the IP network using

software components that operate on the VxWorks™ real-time operating

system.

The Signaling Server has both an ELAN and TLAN network interface. The

Signaling Server communicates with the Call Server through the 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

• SIP/H.323 Signaling Gateways

• Network Routing Service

• Element Manager

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 Configuration (553-3001-213).
