Nortel DMS-100 Test Desk Trunk Group Type |
Test Desk Trunk Group Type
In a DMS-100 end office, incoming and outgoing trunk group type TD connects with a test desk (for example, #14 Local Test Desk [LTD], #3 Local Test Cabinet [LTC]). Members of these trunk groups have Product Engineering Codes (PEC) of NT2X90AB or NT2X90AD.
If the dialed number is busy, the trunk is connected automatically to the line through Metallic Test Access (MTA).
Line Equipment Numbers (LEN) that do not have associated directory numbers (for example, multi-line hunt group members) can be addressed by 11 + LEN for testing purposes.
For example, if a trunk group with field VERSION equal to "MLT" or "TSTDK" is connected to a line that has option Plug-Up (PLP), Random Make Busy (RMB), Requested Suspension (RSUS), or Suspended Service (SUS) activated, and a test desk is connected in idle bridge mode to that line, the line will go to treatment Test Desk Bridged (TDBR) in treatment subtable LNT (Line Treatment), if one of the following conditions occur:
Trunk group type TD can, under certain circumstances, be used for verification. Refer to table TRKGRP, type VR for more information.

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.
----------------------------------------------------------------------------------------------
GRPINFO See Subfields Variable Group Information
This field consists of subfields GRPTYP, TRAFSNO,
PADGRP, NCCLS, TRAFCLS, SELSEQ, TRKDIR, PRTNM,
SCRNCL, SNPA, ORIGSCRE, VDEVAR, TDTYPE, and
BARGE
GRPTYP TD Group Type
Enter "TD" to specify the incoming and outgoing
test desk trunk group type.
TRAFSNO Numeric Traffic Separation Number
(0 to 127) Enter the incoming and outgoing traffic separation
number assigned to the trunk group. If it is not
required, enter "0" (zero).
If switching unit has feature package NTX085AA
(Traffic Separation Peg Count), enter a number
between 1 and the value of office parameter
TFAN_IN_MAX_NUMBER in table OFCENG.
For switching units without feature package
NTX085AA, enter 1 to 15.
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.
PADGRP Alphanumeric Pad Group
(1 to 5 Enter the name of the pad group assigned to
characters) the trunk group in table PADDATA.
Refer to the description of table PADDATA
(Pad Data) for additional information.
NCCLS NCBN, NCID, Operational Measurements No-Circuit Class
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,
this field is not required. Enter "NCRT"
(No-Circuit).
The initial value for this trunk group type
is "NCRT".
For more information, refer to table TRKGRP
and the Operational Measurements Reference
Manual.
TRAFCLS Alphabetic Traffic Usage Class
(2 characters) Enter the traffic usage class assigned to the trunk
group.
SELSEQ MIDL, CWCTH, Select Sequence
CCWCTH, ASEQ, If the trunk group direction is incoming,
or DSEQ sequential selection does not apply. Enter "MIDL".
If the trunk group is outgoing and feature package
NTX244AB (Enhanced Sequential Trunk Hunting) is
present, base the selection order on the order of
the trunks in table TRKMEM, and enter:
* CWCTH or CCWCTH for clockwise or
counter-clockwise circular trunk hunting
from the most recently released trunk in
the trunk group, if the far-end is CCWCTH
or CWCTH respectively, or:
* ASEQ or DSEQ for ascending or descending
sequential selection, if far-end is DSEQ or
ASEQ respectively.
Note: A trunk group trunk selection method cannot
be changed. If a change in the selection
method is required, a new trunk group must
be created with the required trunk selection
method. The individual trunks with the old
selection sequence must be deleted from the
old trunk group and then added to the new
trunk group. For an existing trunk group,
the selection sequence may be changed to ASEQ
from DSEQ or from DSEQ to ASEQ if all the
trunk members are Installation Busy (INB) or
Unequipped (UNEQ).
TRKDIR IC or OG Trunk Direction
Enter "IC" to specify that the direction of traffic
flow is incoming or "OG" to specify that the
direction of traffic flow is outgoing.
If office parameter TRK_OOS_CHK_ON in table OFCVAR
is set to "Y", all trunks in the group must be busy
before the value of this field can be changed by
Data Modification Order (DMO).
PRTNM Alphanumeric Standard Pre-Translator Name
(1 to 4 If the trunk group is incoming, enter the name
characters) or of the standard pre-translator defined in table
NPRT STDPRTCT to which translation is to route on
receipt of the first incoming digit. If the trunk
group is outgoing, enter "NPRT".
If office parameter TRK_OOS_CHK_ON in table OFCVAR
is set to "Y", all trunks in the group must be busy
before the value of this field can be changed by
DMO.
SCRNCL Alphanumeric Class-of-Service Screening Table Name
(1 to 32 If class-of-service screening is required, enter
characters) the name of the class-of-service screening
or NSCR table (datafilled in table SCRNCLAS) to which
digit translation routes.
If class-of-service screening is not required,
enter "NSCR" (no screening).
If the trunk group is outgoing, enter "NSCR".
SNPA Numeric Serving Numbering Plan Area
(3 digits) Enter the code in table HNPACODE to which
translation routes for digit translation.
If the trunk group is outgoing, enter "000".
ORIGSRCE LCL or NLCL Originating Source
If the trunk group is incoming, enter the
originating source of the call, Local (LCL)
or Non-Local (NLCL). This field is used to
screen calls in subtable HNPACONT.HNPACODE.
If the trunk group is outgoing, enter "LCL".
VDEVAR See Subfield Variable Digit Data
This field consists of subfield VDESEL.
VDESEL Y or N Variable Digit Selector
If the number of incoming digits is variable,
enter "Y" and datafill refinements DIGSIN1
and DIGSIN2. If the number of incoming digits
is a fixed quantity, enter "N".
DIGSIN1 Numeric Minimum Number of Incoming Digits
(1 to 18) If the entry in subfield VDESEL is "Y", enter
the minimum number of incoming digits received
on the trunk group.
Entries outside the range indicated for this
field are not valid.
If office parameter TRK_OOS_CHK_ON in table OFCVAR
is set to "Y", all trunks in the group must be busy
before the value of this field can be changed by
DMO.
DIGSIN2 Numeric Maximum Number of Incoming Digits
(1 to 18) If the entry in subfield VDESEL is "Y", enter the
maximum number of incoming digits received on the
trunk group.
Entries outside the range indicated for this field
are not valid.
If office parameter TRK_OOS_CHK_ON in table OFCVAR
is set to "Y", all trunks in the group must be busy
before the value of this field can be changed by
DMO.
DIGREGEN Numeric Digits to be Regenerate
(1 to 4) or N If the entry in subfield VDESEL is "N", enter the
digit string to be prefixed to the incoming digits
to regenerate a seven-digit number. The length of
the digit string entered is subtracted from seven
by the switch to determine the number of incoming
digits to expect.
The regenerated number is then translated in table
STDPRTCT.STDPRT or HNPACONT.HNPACODE, or both.
For example, if the entry is "73", the switch
expects five incoming digits "XXXXX" and
regenerates the number "73XXXXX".
If no digits are to be prefixed, enter "N".
The switch then expects seven incoming digits.
If office parameter TRK_OOS_CHK_ON in table OFCVAR
is set to "Y", all trunks in the group must be busy
before the value of this field can be changed by
DMO.
TDTYP See Subfields Test Desk Type

refinements.
VERSION MLT or TSTDK Version
If the incoming trunk group and switch has an
interface for a mechanized loop tester, enter
"MLT" and datafill refinement DGTTST.
If the incoming trunk group and switch has an
interface for signaling #14 LTD, enter "TSTDK"
and datafill refinements DGTTST and TKTYP.
The default value for TD trunks is "TSTDSK".
DGTTST EXTRCVR or Digit Test
INTRCVR If the value in field VERSION is "MLT" or "TSTDK",
datafill this field to specify whether an internal
or an external receiver is used in the NT2X90AB or
NT2X90AD test trunk for the digit test. For an
internal receiver, enter "INTRCVR". For an
external receiver, enter "EXTRCVR".
The default value is "INTRCVR".
TKTYP REGULAR, Trunk Type
NOTEST, or If the value in field VERSION is "TSTDK", datafill
blank this field.
Enter "REGULAR" for regular trunks or "NOTEST" for
no-test trunks.
BARGE Y or N Barge
Datafill this field to specify whether barging
into an existing call is allowed.
If barging is allowed, enter "Y". Otherwise,
enter "N".
The default value for this subfield is "N".
