24 Description and featuresThe following software components operate on the Signaling Server:• "Terminal Proxy Server" (page 24) (TPS)• "SIP/H.323 Signaling Gateways" (page 24)• "Network Routing Service" (page 25) (NRS)• "Element Manager" (page 25)All the software elements can coexist on one Signaling Server or resideindividually on separate Signaling Servers, depending on traffic andredundancy requirements for each element.For more information about H.323 and SIP Trunking, refer to IP PeerNetworking: Installation and Configuration (NN43001-313) .Terminal Proxy ServerThe Terminal Proxy Server (TPS) acts as a signaling gateway betweenthe IP Phones and the Call Server using the UNIStim protocol. The TPSperforms the following functions:• converts the IP Phone UNIStim messages into messages the CallServer can interpret• allows IP Phones to access telephony features provided by the CallServerThe TPS also controls the IP Phone registration.SIP/H.323 Signaling GatewaysSIP/H.323 Signaling Gateways are software components configured onvirtual loops, similar to IP Phones. SIP/H.323 Signaling Gateways bridgeexisting call processing features and the IP network. SIP/H.323 SignalingGateways also enable access to the routing and features in the MCDNfeature set.Note 1: The SIP/H.323 Signaling Gateway must register with theNetwork Routing Service (NRS).Note 2: Virtual TNs enable you to configure service data withouthardwiring IP Phones to the CS 1000S system. Virtual TNs areconfigured in LD 97.To support IP Peer Networking, dual Call Servers in a CS 1000M SmallSystem must be associated with Signaling Servers that run SIP/H.323Signaling Gateway software. The number of Signaling Servers requireddepends on the capacity and level of redundancy required.Nortel Communication Server 1000Communication Server 1000M and Meridian 1 Small System OverviewNN43011-110 01.01 StandardRelease 5.0 30 May 2007Copyright © 2003 - 2007, Nortel Networks.
