ISDN Support
Description
CPC-EX supports ISDN-PRI (Integrated Services Digital Network --
Primary Rate Interface). This ISDN Interface provides 23 voice channels
(“B” channels) and a control channel (“D” channel) over a 4-wire circuit.
One program address, for Trunk Circuit Type (FF2 (trunk #)# 21#), has
been modified to allow for ISDN. This modification is described below. In
addition, CPC-EX provides several additional programming addresses to

detail on ISDN, are described in the
ISDN Reference Manual, Part No.
