Trunk Type
A normal dial type trunk, hotline type trunk, mixed type trunk and a special trunk can be interfaced with the
Vision. These parameters should be programmed for these lines.
Normal Dial type trunk is the conventional trunk available from the Service Provider. Hotline Dial type trunk is a
special trunk available from the Service Provider, which works as normal dial type for some time after grabbing
the trunk and thereafter works as Hotline.
Hotline type trunk is the trunk connecting two destinations immediately on grabbing it. Special trunk is a trunk
used by big organization like Gujarat Electricity Board etc. for special purpose.
Use following command to define a trunk type:
3103-1-Trunk-Code
Where,
Trunk = Trunk software port number from 0 to 2.
Code Meaning
0 Normal Dial type
1 Delayed hotline type
2 Hotline type
By default, Trunk Type is Normal Dial Type.
Example:
Let us program trunk port 2 for hotline dial type:
1303-1-2-1
Speech Connection Delay Timer
It is the time after which the system gives dial tone to the station user on grabbing the trunk line. To understand
the significance of this timer, let us consider a situation. A telephone line coming from an old telephone
exchange is interfaced with the Vision. Now when the user station not having access to long distance numbers,
grabs a trunk line and dials a number 1022-26305555. The PBX allows this number since it starts with 1 but
since the actual dial tone from the telephone exchange comes after some time, the telephone exchange
interprets this number as 022-26305555 and establishes the speech. This way a station user not having
access to this number can dial out a long distance number. To avoid this situation, Vision offers this timer. This
timer can be set for individual trunks.
Use following command to program speech connection delay timer for trunk:
3104-1-Trunk-Speech Timer
Where,
Trunk is the software port number from 0 to 2.
Speech Timer is from 0 to 9.
Use following command to program speech connection delay timer for all trunks:
3104-*-Speech Timer
Where,
Speech Timer is from 0 to 9.
Trunk First Digit Wait Timer
Trunk first digit wait timer-This timer signifies the time for which the Vision waits for the first digit after
grabbing the trunk.
Command : 3010-Seconds
Default : 25 seconds.
Valid Range : 000 to 255 seconds.
