ISDN/PRI S-Point Interface
UK/Malaysia/Indonesia: The System supports Integrated Services Digital Network (ISDN) Primary
Rate Interface (PRI) terminal equipment with the ISDN/PRI S Point Interface (VB-44540UK).
The primary rate interface provides 30B (bearer) plus one D (data) channel support (30B +D;
1984kbps).
Either 8 or 30 circuits may be enabled on the interface. Each enabled group of 8 circuits requires
a slot position in the System. Fully used cards occupy four slot positions.
HK/Taiwan: The System supports ISDN-PRI terminal equipment with the ISDN/PRI S Point
Interface (VB-44540). The PRI provides 23 B (bearer) plus 1 D (data) channel support (23B + D;

Flexible Numbering Plan
Description
The System provides flexible numbering for feature access special numbers and extension numbers.
The dialling plan allows settings for digits dialled at dial tone, digits dialled at ringback tone, digits
dialled at busy tone, two patterns of feature codes dialled at dial tone, two patterns of feature codes
dialled at ringback tone, and two patterns of feature codes dialled at busy tone.
Feature access codes can be used when replacing another PBX system with a ICX 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).
