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.

The following table lists the datafill for table TRKGRP, type VR.

                                             This field consists of subfield CLLI.
       
         CLLI            Alphanumeric        Common Language Location Identifier
                         (1 to 16            Enter the Common Language Location Identifier
		         characters)         (CLLI) name assigned to the trunk group in 
			                     table CLLI.

                                             The operator verification trunk group for the 
					     switch has pseudo-CLLI VER90 in table CLLI.

                                             The codes in table CLLI for operator verification 
					     trunk groups for remote sites are defined by the 
					     operating company.

					     For assignment of operation verification trunk 
					     groups for remote switches, see table SITE.

                                             Incoming and outgoing traffic separation 
					     numbers 1 to 9 should be reserved for 
					     generic traffic separation numbers.
					     Refer to the description of table TFANINT 
					     (Traffic Separation Intersection) for 
					     additional information.

                         NCIM, NCIT,         Enter the Operational Measurements (OM)
			 NCLT, NCOF,         No-Circuit Class (NCCLS) to indicate which
			 NCON, NCOT,         OM register is incremented if treatment
			 NCRT, NCTC,         Generalized No-Circuit (GNCT) occurs.
                         or NOSC
			                     If the trunk group direction is incoming,
