Supporting Isdn Connectivity - Avaya Scopia XT7100 Deployment Manual

A gatekeeper allows the XT Series to dial aliases instead of IP addresses for endpoints in the
private network, while for public endpoints, you must dial IP addresses. Without a gatekeeper,
all endpoints must be referenced using IP addresses.

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 Scopia
described below. The system then automatically and transparently takes care of setting the bit rate
and call routing through the Scopia
A single gateway can serve multiple endpoints. For example, if your organization needs to enable 5
®
Avaya Scopia XT Series endpoints with ISDN connectivity (at a speed of 256bps), you can use
®
one the Scopia Gateway for ISDN, which supports 5 concurrent calls of 256bps each.
