Dialling an exchange access prefix
The allocation of prefixes to access types is set out in the numbering plan, where
the prefixes can be configured (see "Numbering Plan Identifiers", page 161).
Exchange access prefixes are used to dial the following access types:
• Exchange access, Business:
The call is routed via the route configured for the subscriber.
The call charges are logged (among others) under Business on the subscriber
counter (for more information on call charge allocation see "Individual charge
counting or ICC", page 361).
• Exchange access, Private:
The call is routed via the route configured for the subscriber.
The call charges are logged (among others) under Private on the subscriber
counter.
• Cost centre selection:
The call is routed via the route configured for the subscriber.
The call charges are logged (among others) on the counter for the selected cost
centre.
• Route selection:
The call is routed via the route selected by means of a prefix.
The call charges are logged (among others) under Business on the subscriber
counter.
Dialling an abbreviated dialling Number
With an abbreviated dialling number dials the stored phone number. The phone
number must have an exchange access prefix.
The digit barring facilities are bypassed. If the call destination for an abbreviated
dialling is to be barred using digit barring, the abbreviated dialling number must
be entered in the internal digit barring.
The call is routed via the subscriber’s route, provided the stored phone number
does not already have a prefix for exchange access with route selection.
