Alphanumeric Display

This feature provides for the attendant to have calling number, class-of-service or class-of-restriction, incoming call ID, and trunk ID displayed at the console. Calls to and from a System 75 or Generic 1 have calling/called party identification transparency only when they are directly connected, without an intervening DIMENSION, System 85, or Generic 2 communications system.

Automatic Circuit Assurance

This feature monitors call durations on assigned trunks and automatically generates a referral call when switch software detects a possible malfunction. For DIMENSION, System 85, and Generic 2 communications systems, the referral call can route to one designated local attendant or to Centralized Attendant Service (CAS). For the System 75 and Generic 1, the referral call destination can be the attendant group, a specific attendant, or a display-equipped voice terminal. Only a CAS attendant can turn on or off this feature for trunks at a distant node/endpoint. For referral calls from distant nodes/endpoints, the alphanumeric display shows the trunk group number (trunk group access code in System 75 and Generic 1), individual trunk number, and reason for referral (short or long holding time).

Attendant Control of Trunk Group Access

The attendant can control access to trunk groups assigned to the local node/endpoint or any DCS node/endpoint. To control a trunk group at a distant node/endpoint, the attendant must use a Direct Trunk
