FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
Individual blocking of DID calls
You can block extensions individually to receive DID
calls.
Calls to or diversion to the OPERATOR
If a name string has been programmed for the relevant
trunk, the OPERATOR receives a message on the
display stating that the call is on a DID-trunk.
If the call is diverted to the OPERATOR the
right-hand side of the display will state who has been
called and the reason for the diversion.
Capacity
The number of DID - trunks solely is limited by the
number of trunk board positions .
The maximum number of trunks should not exceed
60.
Limitations
DID often means that the public network needs to be
adapted for this function.
Different countries use different types of DID.
For connection purposes it must be clearly established
whether the local DID-signalling is supported in
ASB 150 02.
Many signal criteria are programmable in ASB 150 02,
whereas others can demand other types of printed
board assemblies (PBAs).
The external call number to the OPERATOR will
usually need conversion to the call number used in
ASB 150 02.
Some public exchanges send more or fewer digits than
those in the number series used in ASB 150 02.
Via command digits can be added to the external
number or received first digits can be ignored.
Note that in order to be able to make incoming external
calls to PBX-groups, fictive numbers etc., these must
have the same number length as extension numbers.
Programming
To obtain an overview of the relevant commands for
signalling, diversion (rerouting ) prerequisites and
operator directory numbers see TRUNK,
facility description 486/155 34-ASB 150 02 Uen.
For the programming of answer (divertee) positions for
diversion and rerouting see ANSWER POSITION(S)
FOR TRUNKS, facility description 112/155 34-ASB
150 02 Uen.
The DID-lines are to be named to allow the operator to
identify diverted (rerouted) calls.
See TELEPHONE DIRECTORY,
facility description 481/155 34-ASB 150 02 Uen.

Equipment
For DID the hardware for the trunks must be adapted
to suit the relevant type of DID.
