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 576HD 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).
