Trunk Group Busy Lamp
General Description
This feature provides the ATTENDANT CONSOLE [A-3] with a visual indication when all trunks in a particular
trunk group are busy (LDN, WATS, FX, DOD, CCSA, TIE or Special Trunks). Assignment of the TGBLs is made
using the MAINTENANCE ADMINISTRATION TERMINAL (MAT) [M-18].
Operating Procedure
No manual operation is required.
Service Conditions
1.
The ATTENDANT CONSOLE [A-3] must have a designated TRUNK GROUP BUSY LAMP (TGBL)
section.
2.
This feature may be used on trunk groups consisting of WATS, TIE, FX, and special trunks.
3.
Ten TGBLs are available on each Attendant Console.
4.
Trunk Group Warning to indicate when a preset number of trunks in a group is busy is not provided.
5.
Trunk groups cannot be combined to light a common TGBL.
6.
A maximum of 10 trunks including LD and TIE are displayed on an Attendant Console.
7.
Desk Console cannot be used to activate this feature.
Interactions
1.
ATTENDANT CONSOLE [A-3] number is the equivalent to the trunk number when assigning the

2.
The ATRK command must be assigned before the ATGL command. If ATRK is not assigned first,
ERROR: 0245, “ATTENDANT CONSOLE [A-3] not assigned yet”, will be indicated.
