Signaling Server

CS 1000M systems use a Signaling Server. The Signaling Server provides a central processor to drive the signaling for IP Phones and IP Peer Networking. The Signaling Server is an industry-standard PC-based server that provides signaling interfaces to the IP network, using software components that operate on the VxWorks™ real-time operating system.

The Signaling Server can be installed in a load-sharing redundant configuration for higher scalability and reliability. The following software components can operate on the Signaling Server.

•Terminal Proxy Server (TPS)

•SIP/H.323 Gateway Signaling software

•Network Routing Service (NRS) (optionally redundant)

•Element Manager web server

•Application Server for Personal Directory, Redial List, and Callers List for UNIStim IP Phones

Signaling Server is an application server which houses any combination of Gatekeeper, H.323 Gateway, Line Terminal Proxy Server and Element Manager. The Signaling Server is mounted on a 480 mm (19 in.) rack (see Figure 11).
