ISDN/PRI S-Point Interface
The System supports ISDN-PRI terminal devices with the ISDN/PRI S Point Interface (VB-44540).
The PRI provides 23 B (bearer) plus 1 D (data) channel support (23B +D; 1544 kbps).
Either 8, 16, or 24 circuits may be enabled on the interface. Each enabled group of 8 circuits requires
a slot position in the System. A fully used card uses 3 slot positions for the DBS 576.
