FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
See AUTOMATIC CALLBACK - TRUNK/ROUTE,
document 116/155 34-ASB 150 02 Uen.
Capacity
32 different public numbers can be assigned to the
trunks. Up to 16 digits can be programmed per public
number.
The maximum permissible number of routes is 256.
The maximum permissible number of trunks per route
is limited to 46.
If the total number of trunks to one destination exceeds
46, it is recommended that the remaining trunks are
programmed as incoming only.
The number of reselection possibilities for alternative
route selection is two.
The maximum number of digits that can be added to
the original number on reselection is 10.
Limitations
The possibility, from a certain extension or trunk, to
access a desired route is determined by the traffic
group matrix.
Trunks that are not placed in a route can only be
accessed by dialling the individual directory number of
the trunk or by pressing a programmed external line
key.
Such a line can be utilised as a private trunk.
If so desired, a trunk can be included in several routes,
for example in a private group network with fixed
length numbering scheme where different first digits
denote different exchanges but where all calls go to
the same group of trunks.
Programming
On initiation of the system all trunks belong to the
same route. The call digit (directory number) of this
route is "0".
5401
Create route
Each new route must be created and assigned a
directory number.
3301
Random selection ?
The search order in a new route uses the random
selection principle but can be altered so that it always
begins with trunk 1.
3201
Route members's dir no.
When a new route has been created it is necessary to
program the trunks that are to be members of the
route. This applies also when a new member is to be
added to or deleted from an existing route.
3302
Callback allowed ?
If all trunks are busy extensions can order automatic
callback - busy trunk.
5501
Delete route
An existing route can be removed via command.
5608
Alter route number
The existing directory number of a route can be
altered.
