CHAPTER 8. USING THE CONSOLE TO TROUBLESHOOT THE SYSTEM

•Trunk Group Busy/Warning indicators to Attendant —used to provide an indication of trunk usage.

•Trunk Identification (V2, V3, and Generic 1 systems)—used to specifically identify a trunk where trouble is encountered.

Automatic Circuit Assurance (ACA)

This feature helps the attendants to identify possible faulty trunks. The system maintains a record of individual trunk activity relative to short- and long-holding time calls. The system automatically initiates a referral call when it detects a possible failure. The attendant-group or an individual attendant can be assigned as the referral call destination.

A referral call will arrive on an idle call appearance. When you press that call appearance button, the display identifies the call as an ACA call, identifies the trunk group access code and the trunk group member number, and shows the reason for referral (short- or long- holding time). This information remains displayed until you release the call. You can then use the Busy Verification of Terminals and Trunks feature to check the trunk.

The ACA feature provides better service through early detection of faulty trunks and, consequently, reduces out-of-service time. Some types of trunk failures cause people to shorten their calls. For example, an excessive number of short calls may indicate a noisy trunk. Similarly, a trunk that remains busy for an abnormally long time may be permanently busy due to a trunk fault. The ACA feature takes advantage of these characteristics to identify possibly defective trunks.

The ACA must be enabled by the System Manager. Once this is done, one attendant console per system. can be assigned an ACA button to activate and deactivate the ACA referrals. The ACA should remain activated at all times if it is enabled at your system.
