Supporting ISDN Connectivity
The SCOPIA XT Series supports ISDN connectivity, allowing calls from endpoints to be routed to
the relevant conference using the SCOPIA BRI (Basic Rate Interface) and PRI (Primary Rate
Interface) gateways.
RADVISION has implemented a special pairing mechanism between the gateway and the
endpoint so that ISDN dialing is very simple. After pairing the systems, the participants place
ISDN calls by dialing the remote party ISDN number. The system automatically and
transparently takes care of setting the bit rate and call routing through the ISDN gateway.
A single gateway can serve multiple endpoints. For example, an organization needs to enable
5 endpoints with ISDN connectivity. Assuming the requested ISDN connectivity speed is
256bps, use only one ISDN PRI gateway as it can support 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.
Implementing External API Control
The SCOPIA XT Series has a feature-rich API. Using this API, integrators can implement AMX
and Creston applications to control the XT Codec Unit. The API is implemented as commands
over the Ethernet interface. Contact RADVISION customer support for a copy of the API
documentation.
