Nortel DMS-100 Incoming End Office Trunk Group Type |
Incoming End Office Trunk Group Type
In a DMS office, incoming trunk group type TI connects with an end or toll office for local, direct, or tandem switching.
If the trunk group uses dial pulse signaling and trunk-to-trunk overlap outpulsing, the variable number of digits format is required. The minimum number of digits specified is the number of digits received before overlap outpulsing starts.
Datafill
For trunk group type TI, table TRIGGRP must be datafilled before table TRKGRP. For additional dependencies, refer to section "Table Size" in table TRKGRP.
The following table lists the datafill for table TRKGRP, type TI.

Field Descriptions - Incoming End Office
Field Subfield Entry Explanation and Action
----------------------------------------------------------------------------------------------
GRPKEY See Subfield Group Key
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, PRTNM, SCRNCL, SNPA,
ORIGSRCE, VDEVAR, and OPTIONS.
GRPTYP TI Group Type
Enter the incoming end office trunk group type TI.
TRAFSNO Numeric Traffic Separation Number
(0 to 127) Enter the incoming traffic separation number
assigned to the trunk group. If a traffic
separation number is not required, enter "0".
If switching unit has feature package NTX085AA
(Traffic Separation Peg Count), enter a number
between 1 and the value of office parameter
TFAN_OUT_MAX_NUMBER in table OFCENG.
For switching units without feature package
NTX085AA, enter 1 to 15.
It is recommended that incoming and outgoing
traffic separation numbers 1 to 9 be reserved
for generic traffic separation numbers.
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 NCRT Operational Measurements No-Circuit Class
This field is not required for incoming trunk
groups. Enter "NCRT" (no circuit).
TRAFCLS Alphanumeric Traffic Usage Class
(2 characters) Enter the traffic usage class assigned to
the trunk group.
PRTNM Alphanumeric Standard Pretranslation Name
(1 to 4 Enter the name of the standard pretranslator
characters) or datafilled in table STDPRTCT to which translation
NPRT routes on receipt of the first incoming digit.
If pretranslation is not required, enter "NPRT"
(no pretranslator). 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).
SCRNCL Alphanumeric Class of Service Screening Table Name
(1 to 32 If class-of-service screening is required, enter
characters) or the name of the class-of-service screening table
NSCR (datafilled in table SCRNCLAS) to which digit
translation routes. If class-of-service screening
is not required, enter "NSCR" (no screening).
SNPA Numeric Serving Numbering Plan Area
(3 digits) Enter the code in table HNPACODE to which
translation routes for digit translation.
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.
ORIGSRCE LCL or NLCL Originating Source
Enter the originating source LCL (local) or NLCL
(non-local).
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" and datafill refinement
DIGREGEN.
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.
DIGSIN1 Numeric Minimum Number of Incoming Digits
(1 to 18) If the entry in field VDESEL is "Y", enter the
minimum number of incoming digits that can be
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" (yes), 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 field VDESEL is "Y', enter the
maximum number of incoming digits that can be
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" (yes), all trunks in the group must
be busy before the value of this field can be
changed by DMO.
DIGREGEN Numeric Digits to be Regenerated
(1 to 4 digits) If the entry in field VDESEL is "N", enter the
or N digit string (one to four digits) 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.
OPTIONS See Subfield Options
This field consists of up to two multiples of
subfield OPTION and refinements.
OPTION BCNAME Option
To specify the bearer-capability-name option,
enter "BCNAME" and datafill refinement BCNAME.
If option BCNAME does not apply, leave this field
blank.
BCNAME Alphanumeric Bearer Capability Name
(1 to 16 If the entry in field OPTION is "BCNAME", enter
characters) the bearer capability to be used by this trunk
group. Refer to table BCDEF for the current
list of available bearer capabilities.
