Trunk Group Busy/Warning Indicators to Attendant

This feature provides the attendant with a visual indication of the trunk group status for each of the Trunk Group Select buttons located on the console.

Six of the Trunk Group Select buttons on the Basic Console have associated Warning and Busy lamps. The other six buttons have only associated Busy lamps. The lamps function as follows:

Busy Lamps

Light when all trunks in the associated trunk group are busy.

Warn (Warning) Lamps

Light when a preset number of trunks in the associated trunk group are busy.

All 12 of the Trunk Group Select buttons on the Enhanced Console have 3 lamps associated with each button. The Busy and Warn lamps function the same as on the Basic Console. In G1, Basic and Enhanced attendants may have feature buttons administered as (Local-tgs)and

(Remote-tgs)for up to 12 additional trunk group select buttons. The lamp on a local-tgs or remote-tgs button lights when all trunks in its associated trunk group are busy. If the local-

tgs or remote-tgs button has two lamps, the top lamp is not used and the bottom lamp lights when all trunks in its trunk group are busy.

Observing these indicators can alert you to unusual or suspicious conditions such as groups that are always busy or never busy. Knowing what hours of the day are the “most busy” and the “least busy” in terms of trunk usage is also useful in analyzing possible trunk problems. For example, if the Busy lamp for a particular group remains lighted during a normally slack period, it is possible that one or more trunks are out-of-service but appear to be busy. On the other hand, a trunk group with lamps that never light may also have a trouble condition. Use the Busy Verification feature to test suspected faulty trunks.
