Features & Specifications, ISDN Basic Rate Interface
A6-506000-642-02
DID and Malicious Call Traces are network provided and have to be subscribed from the
service provider before use.
Two Basic Rate Interfaces give 4 trunks.
Calls arriving on BRI ISDN lines can be handled as trunk calls or indial calls, depending
upon system programming. When a service number is assigned to a trunk port, that trunk
will ring when a call is made to that number. Alternately, when a service number is
assigned as a station indial number, a call to that number will be treated as an indial call
and will ring directly at the station.
The system supports Point to Multi-point connections only.
