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, or 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.

Flexible Numbering Plan

Description

The System provides flexible numbering for feature access special numbers and extension numbers.

The dialing plan allows settings for digits dialed at dial tone, digits dialed at ringback tone, digits dialed at busy tone, two patterns of feature codes dialed at dial tone, two patterns of feature codes dialed at ringback tone, and two patterns of feature codes dialed at busy tone.

Feature access codes can be used when replacing another PBX system with a DBS 576 system. Rather than learning the new access codes, the System feature access codes can be changed to match the old system. As a result, telephone users are less confused by the change and the requirement for retraining is reduced. Two sets of feature access codes are available (one of the two must be assigned to the terminal).
