Trunk Operation Direct Inward System Access Disa

SX-200 General Information Guide

system on DID type trunks are assumed to be outside calls. Callers therefore receive different call progress tones. Call handling differs from Tie and DISA trunk type calls, which are assumed to be internal calls.

Trunk Operation - Direct Inward System Access (DISA)

The DISA feature allows an external caller to access the system by dialing the directory number of a special DISA trunk and then dialing a security code. After the code is dialed the system returns Dial Tone to the caller, who may then access any features in the DISA trunk’s COS which do not require a Switch Hook Flash. Optionally, the external caller can be required to enter a special account code rather than the standard DISA Access Code. See Account Codes

-Verified (Special DISA), DISA trunks can be supported on many different hardware types. See Trunk Support - T1, Trunk Support - DID, Trunk Support - E & M. A trunk can be programmed as DISA at all times, or during night service only.

Trunk Operation - Non-Dial-in CO

CO trunks usually carry calls between the local central office and the PBX. Calls arriving on CO trunks are assumed to be outside callers. Callers therefore receive different call progress tones. Call handling differs from Tie and DISA trunk type calls, which are assumed to be internal calls. CO trunks are assigned an origination point for DAY, NIGHT1, and NIGHT2 service. They can optionally be assigned as a dedicated line on a SUPERSET telephone. The NIGHT1 or NIGHT2 service for CO trunks can be changed directly from the Attendant Console.

Trunk Operation - Tie

Tie trunks allow incoming trunk calls to reach extensions directly, without attendant intervention or assistance. The number of digits expected from the trunk is unknown. Digit absorption and adding prefix digits can be done. Calls coming into the system on Tie type trunks are assumed to be callers from inside the company, similar to DISA trunk type calls. The callers therefore receive the same call progress tones that internal callers hear and may have access to many extension features.

Trunk Recall

The Trunk Recall feature provides an alternate recall point for trunks in the system. The alternate recall point can be specified for each tenant and each NIGHT/DAY service. Under the following conditions, trunks are rerouted to the alternate call point:

•For all trunk types, when an extension with a trunk on Consultation Hold is listening to reorder tones and times out. The trunk is removed from consultation hold and rerouted.

•For DISA and CO trunks, when a trunk recalls from campon or ringing an extension. See Recall.

Trunk Support - CO (LS/GS)

The SX-200 EL and SX-200 ML systems support CO (LS/GS) trunks with the LS/GS Trunk card in digital bays. The SX-200 SPINE supports LS/CLASS trunks with the LS/CLASS trunk module. The SX-200 rackmount cabinet supports LS/CLASS trunks with the LS/CLASS Trunk card.
