Nortel DMS-100 Enhanced 911 Emergency Service Trunk Group Type |
Enhanced 911 Emergency Service Trunk Group Type
Trunk group type E911 (Enhanced 911 Emergency Service) is used for dedicated 911 trunks that are incoming to a tandem office.
E911 type trunks support both Multifrequency (MF) and Dial-Pulse (DP) signaling formats.
If office parameter E911_PSAPS_USING_1_INFO_DIGIT in table OFCSTD (Office Standard) is set to "Y" (yes), datafill table E911NPD (Enhanced 911 Numbering Plan Digit) prior to datafilling field NPA in table TRKGRP (Trunk Group) for group type E911.
An Emergency Service Number (ESN) datafilled in the E911 trunk group data must also be datafilled in table E911ESN (Enhanced 911 Emergency Service Number).
Ensure that a default ESN for table TRKGRP and group type E911 is datafilled in table E911ESN. Otherwise, calls on this trunk group cannot be routed and are sent to vacant code treatment.
Datafill
The following table lists the datafill for table TRKGRP, type E911.

Field Descriptions - E911
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, SNPA, ECPHTIME, ORIGHOLD, SDATA,
ANISEIZ, ANIPDIAL, ANIREQSG, ESCO, ESN, EXTSIG,
and PRTNM.
GRPTYP E911 Group Type
Enter E911 to specify the group type for
enhanced 911 emergency service.
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.
NCCLS NCRT Operational Measurements No-Circuit Class
This field is not required for incoming trunk
groups. Enter "NCRT" (no circuit).
PRTNM Vector Pretranslator Name
(up to 8 To activate this option, enter the value in table
characters) STDPRTCT. Then enter the data for field PRTNM in
table TRKGRP for the E911 MF trunk with that value.
The default datafill for an E911 MF trunk is "NPRT"
(Nil Pretranslator).
SNPA Numeric Serving Numbering Plan Area
(5 digits) Enter the serving NPA of the E911 trunk group that
has a Numbering Plan Digit (NPD) datafilled in
table E911NPD.
ECPHTIME Mumeric Enhanced Called Party Hold Time
(0 to 255) This entry indicates the number of seconds ECPH is
active.
ORIGHOLD Y or N Originator Hold
If the end office at which this trunk originated
supports the operator hold function. Otherwise,
enter "N" (no).
SDATA See Subfields Signaling Data
This field consists of subfield SIGFMT and
refinements.
SIGFMT AMR4, AMR5, Signaling Format
or BELL Enter the format of the Automatic Number
Identification (ANI) information that is incoming
on the trunk.
If the format type is AMR4, enter "AMR4" and
datafill refinement NCATDIGS.
If the format type is AMR5, enter "AMR5" and
datafill refinement NCATDIGS.
If the format type is BELL, enter "BELL" and
datafill refinement INFODIGS.
NCATDIGS Numeric Number of Category Digits
(2 or 3 digits) Datafill this field if the value in field SIGMT
is AMR4 or AMR5.
Enter the number of category digits expected
along with the ANI.
INFODIGS Numeric Information Digits
(1 or 2 digits) Datafill this field if the value in field SIGMT
is BELL.
Enter the number of information digits expected
along with the ANI.
ANISEIZ Numeric ANI Seizure Timing
(2 to 30) Enter the time, in seconds, that the trunk waits
for reception of the first ANI digit or signal
after the ANI request signal.
ANIPDIAL Numeric ANI Partial Dial Timing
(2 to 30) Enter the time, in seconds, that the trunk waits
for reception of each ANI digit or signal after
the first digit.
ANIREQSG REV or WK ANI Request Signal
Enter "REV" to specify that a reversal signal is
used to request ANI information. This entry value
is used for multifrequency or dial-pulse signaling.
Enter "WK" to specify that a wink signal is used
to request ANI information. This entry value is
used for Public Safety Answering Point (PSAP)
signaling.
ESCO Numeric Emergency Service Central Office
(0000 to 9,999) Enter the number representing the end office at
which the E911 trunk originated.
ESN Numeric Emergency Service Number
(000 to 15,999) Enter the number associated with the Emergency
Service Zone (ESZ). This number is used to obtain
the Directory Number (DN) of the primary PSAP to
which the call is routed by default.
EXTSIG Y or N Extended Signaling
Enter "Y" to specify that the trunk uses the
extended signaling protocol. Enter "N" to turn
off this option.
ACKWINK Y or N Acknowledgment Wink
Enter "Y" to receive an ACKWINK on incoming
wireless calls over MF trunks to the E911 tandem.
The E911 tandem receives the ACKWINK after
receiving digits.
The default setting is "N". To change the ACKWINK
field to "Y", set the EXTSIG field to "Y".
OFBSR Y or N Off-Board Selective Routing Database
Enter "Y" if facility uses the OFBSR for
translations and routing of both MF and ISUP
E911 trunks.
