INTER-PBX COORDINATED STATION NUMBERING PLAN-PRI

I-27 INTER-PBX COORDINATED STATION NUMBERING PLAN-PRI
1. General Description
The INTER-PBX COORDINATED STATION NUMBERING PLAN-PRI [I-27] feature enables the Main-
Satellite network to coordinate the numbering plan for stations in the network. This feature allows a station at
one switch to call a station at another switch by dialing a unique 3- to 7-digit number with no access codes or
pauses for Dial Tone.
This feature can also be arranged to provide a centralized exchange network capability, which channels access
to and from the public network through a single system switch in the coordinated group.
2. Operating Procedure
This feature is used for the Main/Satellite configuration and may also be provided with main/tributary
configuration. Stations at the main and satellite may dial each other without an intervening Dial Tone. The
dialing plan for an inter-PBX call is the same as for an intra-PBX call. With this arrangement different initial
digits are assigned to stations on different systems.
3XXX
All switches have a coordinated station numbering feature.
Example 1: A station user at the satellite switch dials 5XXX to call a station at the Main switch.
Example 2: A station user at the Main switch dials 3XXX to call a station at the Satellite switch and 4XXX to
call a station at the Tributary switch.
