Trunk Access Groups (TAGs)

All the trunks connected to the system can be clubbed together in different groups which are called Trunk Access
Groups. Trunk Access Groups provide efficient allocation of trunks to different stations.
• A Trunk Access Group can have maximum three trunks and a total of eight such Trunk Access Groups can
be formed.
• A station can be allotted different Trunk Access Groups during Day time and Night time.
• To access these groups, you must dial any of these Trunk Access Codes (TACs) - 0, 5, 61, 62, 63, 64.
• These Trunk Access Groups can be allotted to individual stations.
For example, in Day time, the Trunk Access Code '0' can be assigned to a Trunk Access Group containing
all the trunks. Doing so, on dialing '0' during the Day time, a station user gets any of the free trunks from
the Trunk Access Group.
Similarly, in Night time, the same Trunk Access Code '0' can be assigned to a Trunk Access Group
containing no trunk. Doing so, on dialing '0' during Night time, the station user gets Error Tone.
The following table displays the default mapping among Trunk Access Groups, allowed trunks in each group and
the Trunk Access Codes to be dialed to access the trunks.

a. Dialing TACs 0 and 5 provides access to all the trunks that a VISIONPRO variant currently supports. For example, in
case of VISIONPRO 412, dialing either of these TACs (0 or 5) will provide access to all the four trunks provided they are
free. Similarly, for VISIONPRO 206, dialing TAC 0 or 5 will allow access to all the two trunks provided they are free.
System uses two methods while allotting a trunk from the Trunk Access Group. By assigning the Rotation code to
the Trunk Access Groups, you can define which method should be used. These two methods are as follows.
• Remember the last trunk (Rotation ON): In this method the system remembers the last trunk used and
allots the next free trunk in the group to a station.
• Don't remember the last trunk (Rotation OFF): In this method, the system searches for a free trunk and
this searching starts from the first trunk programmed in the group. If the first trunk is free, it is allotted to the
station. In such case it is possible that first few trunks in a group would be used frequently.
How to configure
Decide the number of Trunk Access Groups to be formed. Program these groups using command 4402.
1.
Program the rotation code to select a trunk within the Trunk Access Group using command 4403.
2.
Set a Trunk Access Group to default settings using command 4401 (if required).
3.
Assign a Trunk Access Group and a Trunk Access Code to a station for Day time.
