The CS1000 Architecture is as shown above. The ELAN is a private management network whilst the TLAN is

connected to the “Public” side. Telephones maybe connected to the TLAN directly or to a network routed from

the TLAN (Sometimes referred to as the CLAN Customer LAN).

IP Sets sit on the TLAN or a network attached to the TLAN. They need to communicate with the Call Server to

make and receive calls and this is done by registering with the Signalling server. The Signalling server runs

several pieces of software but the sets use the TPS, Telephone Proxy Server to register with and to

communicate with the call server.

When a set registers TPS records its Virtual TN and IP address so it can identify it. In the call server the set is

defined using the Virtual TN.

The Media Gateway is used to provide card slots for Digital & Analogue cards and any others required. It also

provides other services but importantly the IP/TDM conversion via “Media Cards”. This the Media Gateway is

the path to traditional TDM phone sets and the PSTN.

When an IP set makes a call it messages the Call Server via the TPS on the Sig server. The Call server locates

the endpoint for the call and manages the connection. If it is from one IP set to another the call server will signal

the destination via the TPS. When the call is established the voice travels directly form IP Set to IP Set and NOT

via the sig server or call server.

If the end point is a TDM set the call server messages the Media Gateway to allocate TDM/IP resource as well

as signalling the traditional set. The Voice path for the completed call would be via a Media Card.
