Supporting Isdn Connectivity - Avaya XT Series Deployment Manual

Planning the Topology of the Avaya Room System XT Series Deployment

Supporting ISDN Connectivity

About this task
The Avaya Room System XT Series supports ISDN connectivity, allowing calls from endpoints to
be routed to the relevant videoconference via the Gateway for ISDN.
For deployments without a gatekeeper, you can dial ISDN endpoints by simply dialing the ISDN
number. To do so, you must first configure the endpoint with your Gateway for ISDN, as described
below. The system then automatically and transparently takes care of setting the bit rate and call
routing through the Gateway.
A single gateway can serve multiple endpoints. For example, if your organization needs to enable
5 Avaya Room System XT Series endpoints with ISDN connectivity (at a speed of 256bps), you
can use one the Gateway for ISDN, which supports 5 concurrent calls of 256bps each.
With the gateway approach less communication lines are needed. As all gateways do not connect
at the same time and not all calls are ISDN, many more endpoints can share the same ISDN
connection and gateway.
Before you begin
Enable Peer-to-Peer mode in the Gateway for ISDN. For more information, see the Gateway
documentation.
