ROUTE SELECTION
Definition
Simple route selection
Route selection means that an extension, by means of
directory number automatically selects a free trunk for
outgoing traffic.
All trunks that run to the same public exchange or
other exchange are called "route".
Each route must be assigned a directory number.
Alternative route selection
Alternative route selection means that if there exist
different paths to reach an addressee and if one path
is blocked, the system can undertake reselection to
another path.
Use
By dialling the route call number directly, the user can
obtain a free trunk to the desired public exchange or to
another exchange.
For alternative route selection the system will
automatically select a trunk in the route that is first in
the order of search.
If there is no free trunk in the normal route the system
will attempt to select a trunk in an alternative route, if
programmed accordingly.
Operation
All telephones
Free trunk available
An outgoing external call can be initiated by dialling the
route's directory number on the key set or rotary dial.
If a free trunk exists in the selected route, the caller will
receive dial tone from the called system.
The display shows the dialled route number:
EXECUTIVE Telephone
STANDARD Telephone
All trunks are busy.
If there is no free trunk, the caller receives busy tone.
The display shows "BUSY" or "B":
EXECUTIVE Telephone
STANDARD Telephone
The caller can now select to terminate or to order
callback to the route.
