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).
