AT&T 75 manual DCS Automatic Circuit Assurance, DCS Busy Verification of Terminals and Trunks

CHAPTER 5. USING THE DCS FEATURES (V2, V3, AND GENERIC 1 SYSTEMS)

On outgoing calls, the display of called party information may be delayed a few seconds until the required information arrives from the remote switch.

DCS Automatic Circuit Assurance

Transparency of the Automatic Circuit Assurance (ACA) feature in a DCS environment allows an attendant at a V2, V3, or Generic 1 end-point node to activate or deactivate ACA referral calls for the entire DCS network. This transparency also allows the referral calls to be generated at a switch other than the switch that detects the trunk problem. Referral calls are handled the same way as in a non-DCS environment. When a referral call is generated from a remote DCS node, the display associated with that call indicates the PBX ID of the remote node that originated the alarm.

DCS Busy Verification of Terminals and Trunks

Attendants can busy verify voice terminals at a remote location by first pressing the Verify button and then entering the desired Uniform Dial Plan extension number. The verification then continues the same as if the voice terminal being verified is on the local switch.

Attendants can also busy verify a trunk at a remote location using two different methods. In the first method the attendant presses Verify, accesses the DCS tie trunk to the remote switch either by trunk access code or Trunk Group Select button, presses Verify again, and then proceeds as if the trunk were on the local switch.

The second method requires a Trunk Group Select button administered for remote trunk group. With this method the attendant presses Verify and the trunk group select button for the remote trunk group followed by the desired member number.

The display for DCS busy verification does not indicate the status of the attempt (i.e., “INVALID”,“TERMINATED”, “BRIDGED”, “OUT OF SERVICE”).

Procedures for activating the Busy Verification of Terminals and Remote Trunks feature are described in Chapter 8.

DCS Call Forwarding All Calls

The operating procedures required to activate and deactivate this feature for an extension at a remote switch are the same as those required at the local switch. However, there are some restrictions on length of the forwarded-to number. When using the console to forward the calls of a remote extension in a DCS environment, the forwarded-to telephone number must not be longer than 10 digits. The 10 digits can include a 3-digit Facility Access Code followed by a typical 7-digit telephone number. Also, no authorization codes can be included in the forwarded-to telephone number.
