Nortel DMS-100 Operator Verification Trunk Group Type |
Operator Verification Trunk Group Type
Outgoing trunk group type VR (verification) in a DMS end office is used by a minibar switch to provide metallic path access to a call-in-progress.
Metallic path access is required if an operator has attempted an authorized call verification on a line that is busy.
Verification calls can originate on trunk group types A5, OC, OP, OI, or TD if one of the following conditions applies:
Trunks with the trunk group type VR are assigned to horizontals of the minibar switches in the table MTAMDRVE (Metallic Test Access Minibar Driver).
Trunks with trunk group type VR are datafilled with card code NT2X90A in table TRKSGRP (Trunk Subgroup).
The hold type for trunk group type verification (VR) type is joint hold. This means that the call is taken down if both the originator and the terminator are on hook.
