Exchange Line Request/Exchange Line Access Number
Proceed as follows:
Using the Configuration Manager (page Public switched tel. networks > Exchange line request)
* Note: Some of the following settings can also be configured seperately for connections/accounts.
System-wide Automatic Exchange Line Request
Requirements:
Emergency call only with disabled exchange line access number
-Using the Configuration Manager (on the following pages)
-Public switched tel. networks > Emergency calls
The PBX automatically distinguishes for each subscriber between internal and external numbers by analysing the digit sequence and the adjustment of the dialled phone number with the internal numbering plan.
* Note: When switched off, the exchange line request type can be set individually for each subscriber.
Exchange Line Access Number
Requirements:
Configured prefixes (country prefix and local area code)
Automatic exchange line request disabled
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.
* Note: 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.
* Note: Changing the exchange line access number is only meaningful if another exchange line access number is normally used (e.g., in England).
* Note: Note that changing the exchange line access number restricts the phone numbering plan.
