Exchange line request
Is required to request an external line (exception: direct exchange access
and automatic exchange line request).
Note:
An available external line is indicated by the external dial tone after the
exchange line access number has been dialled. The external number
can then be dialled.
The factory setting for the exchange line access number on the PBX is
0. This number is not effective at first because automatic exchange line
request is active in the factory settings.
Changing the exchange line access number is only meaningful if
another exchange line access number is normally used (e.g., in
England).
Note that changing the exchange line access number restricts the phone
numbering plan.
