Nortel DMS-100 Intertoll Trunk Group Type |
Intertoll Trunk Group Type
In a DMS toll or end office, two-way, incoming, or outgoing trunk group type intertoll (IT) interfaces with another toll or end office to carry toll connecting traffic including toll access, toll completing, and toll tandem.
In offices without software package NTX052AB Remote Office Test Line (ROTL) that do not have trunk group type T105, the 105 test line can be datafilled as an IT trunk group type.
If overlap outpulsing is required on incoming or two-way Dial Pulse (DP) trunk groups, field OVLP in table TRKSGRP (Trunk Subgroups) must be set to "Y" (yes).
Overlap outpulsing can only apply between incoming and two-way intertoll trunk groups and outgoing and two-way intertoll, local, and Integrated Business Network (IBN) trunk groups.
The standard digit manipulation defined for selector "S" in the route reference subtables is applicable to outgoing and two-way intertoll trunk groups, except when a call is routed from table STDPRTCT (List of Standard Pretranslation Tables).
If no outpulsing is required, fields OPULSTYP and OSTARTSG in table TRKSGRP have the values of "DP" (Dial Pulse) and "IM" (Immediate Dial) respectively. The route reference index for this trunk group is required to use the non-standard format (N) and delete all digits.
If the trunk group has Common Channel Interoffice Signaling (CCIS) supplementary information for the trunk, members are assigned in table C6TRKMEM (CCIS6 Trunk Member Table).
Option BCNAME is only valid for incoming and two-way trunk group types.
Option CELL is not compatible with option E911.
Equal Access for DMS-100 Wireless
When datafilling Equal Access (EA) on the DMS-100 Wireless switch, the wireless portion of an ISUP Integrated Service Link (ISL) trunk must be datafilled as a DID trunk group type with refinement RTEVIAAT set to "Y".
The wireline portion of the ISUP ISL trunk must be datafilled as an IT trunk type. Option CELL must be set to "2A" to support North American EA ISL terminations. A distinct billable number must be designated for option BILLNO for the downstream processor to distinguish the AMA records generated by the wireless DID ISL and non-ISL trunks.
E911 ISUP Trunking
Option E911 provides the ability to route Enhanced 911 Emergency Service (E911) calls directly over Integrated Services Digital Network User Part (ISUP) trunks. Incoming trunks with this option can process E911 calls by selecting the appropriate route to the Public Safety Answering Point (PSAP) using the normal E911 Selective Routing Database (SRDB) or an Off-Board Selective Routing Database (OFBSR).
End Office and Outgoing Trunk Datafill of E911 Option
Offices that are not E911 tandems should not datafill option E911 on any IT trunks. All incoming calls on an IT trunk with option E911 perform a SRDB lookup to determine the caller's Emergency Service Number (ESN). Since there are no valid ESNs in an office that is not an E911 tandem, these calls are routed to treatment. If a 'dummy' PSAP and ESN is datafilled, this allows the calls to complete, but does add an unnecessary step to all incoming calls (the SRDB lookup).
Datafilling option E911 has no effect on outgoing calls.
Datafill of E911 Option on Non-Dedicated Trunks
The following should be considered when data is entered for the E911 option on non-dedicated trunks.
Datafill Sequence and Implications
Table TRIGGRP must be datafilled before table TRKGRP, type IT.
Calls using the default Emergency Service Number (ESN) do not complete if the ESN is not datafilled in table E911ESN (Enhanced 911 Emergency Service Number).
Standard table control error messages are produced as well as the following warning messages:
DANGER - The following warning message is generated if an ESN is datafilled for an E911 trunk group and is not datafilled in table E911ESN, and if office parameter E911_CHECK_DEFAULT_ESN is set to "N": ESN NOT PRESENT IN TABLE E911ESN. THIS ESN MUST BE DATAFILLED IN TABLE E911ESN FOR 911 CALLS TO COMPLETE.
With the following message, no tuple is added to table TRKGRP:
DANGER - The following error message is generated if an attempt is made to datafill an ESN for an E911 trunk group and it is not datafilled in table E911ESN, and if office parameter E911_CHECK_DEFAULT_ESN is set to "Y": ESN MUST BE IN TABLE E911ESN.
For additional datafill dependencies, refer to section "Datafill Sequence" in the general section of table TRKGRP.

calling party number. There is no second attempt.
Note: The WRLS_STD entry applies to incoming
trunks that handle only wireless emergency calls.
The first attempt to enter WRLS_CLD uses the
calling party number. There is no second attempt.
Note 1: The WRLS_CLD entry applies to incoming
trunks that handle only wireless emergency calls
directly from a mobile switching center. The
mobile switching center sends the Pseudo Automatic
Number Identifier (PANI) and callback number in a
non-standard format.
Note 2: The E911SIG option is valid only
for North America.
OFBSR Y or N Off-Board Selective Routing Database
This subfield indicates that the facility uses
the OFBSR or dual OFBSR for selective routing.
The default is "N".
TDMPRFX 0 to 15 Tandem Prefix Value
If datafilled with a non-zero value, this
suboption indicates the originating E911
tandem in a dual super tandem-tandem network.
A new Generic Digits Parameter (GDP) is built
in the IAM to transport the TDMPRFX to table
E911TDRT.
The delivery of the TDMPRFX value in the new
GDP behaves as follows:
* If a non-zero TDMPRFX is datafilled against
an ISUP IT trunk with the E911 option, then
a GDP is built containing the TDMPRFX and
sent on outgoing 911 calls.
* If the TDMPRFX datafill against an ISUP IT
trunk has the default value of "0", and if
no TDMPRFX is received via a GDP, then
outgoing 911 calls do not build the GDP
containing the TDMPRFX.
* If a GDP containing the TDMPRFX is received at
an E911 tandem, the value is stored. It takes
precedence over any datafilled TDMPRFX values
if the TDMPRFX datafilled in table TRKGRP is
non-zero. If datafilled value is "0", the
TDMPRFX from GDP is dropped and not used for
further processing.
* If the TDMPRFX datafill against an ISUP IT
trunk has a default value of "0" and no GDP
is received, the TDMPRFX is ignored.
* On an ONP, if a non-zero TDMPRFX is not
datafilled, a default value of "0" is
transferred.
The TDMPRFX field should be datafilled in the
Super E911 tandems for incoming ISUP IT trunks
with the E911 option. The TDMPRFX field in
other E911 tandems should not be datafilled,
rather the value should be left at the default
of zero.
LRN 10-digit Location Routing Number
directory If field OPTION = LNP, datafill the default 10-
number digit LRN. This field indicates the originating
service provider, used for billing purposes, if
one is not signalled on the incoming trunk.

calls directly from a mobile switching center. The
mobile switching center sends the PANI and callback
number in a non-standard format.
TDMPRFX 0 to 15 Tandem Prefix Value
If datafilled with a non-zero value, this suboption
indicates the originating E911 tandem in a dual
super tandem-tandem network. A new Generic Digits
Parameter (GDP) is built in the IAM to transport
the TDMPRFX to table E911TDRT.
The delivery of the TDMPRFX value in the new GDP
behaves as follows:
* If a non-zero TDMPRFX is datafilled against an
ISUP IT trunk with the E911 option, then a GDP
is built containing the TDMPRFX and sent on
outgoing 911 calls.
* If the TDMPRFX datafill against an ISUP IT trunk
has the default value of "0", and if no TDMPRFX
is received via a GDP, then outgoing 911 calls
do not build the GDP containing the TDMPRFX.
* If a GDP containing the TDMPRFX is received at
an E911 tandem, the value is stored. It takes
precedence over any datafilled TDMPRFX values
if the TDMPRFX datafilled in table TRKGRP is
non-zero. If datafilled value is "0", the
TDMPRFX from GDP is dropped and not used for
further processing.
* If the TDMPRFX datafill against an ISUP IT
trunk has a default value of "0" and no GDP
is received, the TDMPRFX is ignored.
* On an ONP, if a non-zero TDMPRFX is not
datafilled, a default value of "0" is
transferred.
The TDMPRFX field be datafilled in the Super
E911 tandems for incoming ISUP IT trunks with
the E911 option. The TDMPRFX field in other
E911 tandems should not be datafilled, rather
the value should be left at the default of zero.
ORIGHOLD Y or N Originator Hold
Enter "Y" (yes) if the end office at which this
trunk originated supports the operator hold
function. When ORIGHOLD is active, the
originator of an E911 call cannot disconnect the
call. Enter "N" to make ORIGHOLD inactive.
ECPHTIME 0 to 255 Enhanced Call Party Hold
This subfield indicates the number of seconds
that ECPH remains active. ECPHTIME prevents a
caller from disconnecting a call before the call
is answered and before the timer expires. Zero
(0) deactivates ECPH.

from disconnecting a call before the call is
answered and before the timer expires.
Zero (0) inactivates ECPH.
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.
TDMPRFX 0 to 15 Tandem Prefix Value
If datafilled with a non-zero value, this
suboption indicates the originating E911
tandem in a dual super tandem-tandem network.
A new Generic Digits Parameter (GDP) is built
in the IAM to transport the TDMPRFX to table
E911TDRT.
The delivery of the TDMPRFX value in the new
GDP behaves as follows:
* If a non-zero TDMPRFX is datafilled against
an ISUP IT trunk with the E911 option, then
a GDP is built containing the TDMPRFX and
sent on outgoing 911 calls.
* If the TDMPRFX datafill against an ISUP IT
trunk has the default value of "0", and if
no TDMPRFX is received via a GDP, then
outgoing 911 calls do not build the GDP
containing the TDMPRFX.
* If a GDP containing the TDMPRFX is received
at an E911 tandem, the value is stored.
It takes precedence over any datafilled
TDMPRFX values if the TDMPRFX datafilled
in table TRKGRP is non-zero. If datafilled
value is "0", the TDMPRFX from GDP is dropped
and not used for further processing.
* If the TDMPRFX datafill against an ISUP IT
trunk has a default value of "0" and no GDP
is received, the TDMPRFX is ignored.
* On an ONP, if a non-zero TDMPRFX is not
datafilled, a default value of "0" is
transferred.
The TDMPRFX field be datafilled in the Super
E911 tandems for incoming ISUP IT trunks with
the E911 option. The TDMPRFX field in other
E911 tandems should be left at the default of
zero.
CHGNO_TRAFTYPE PBX or ALL Charge Number Traffic Type
If the entry in field OPTION is CHGNUM, select
refinement PBX to provide the CN and OLI
parameters for calls originating on PBX trunks.
Select "ALL" to provide the CN and OLI parameters
for outgoing calls on the following originating
agents: POTS, RES, IBN, or BRI lines; PRI and
ISUP trunks; IBNT2, IBNTI, or PBX trunks;
attendant consoles, or a supported agent routed
through a Virtual Facility Group (VFG).
Select "ALL" to provide OSS7 option OSNC assigned
through table TRKOPTS.
LRN 10-digit Location Routing Number
directory If field OPTION = LNP, datafill a 10-digit
number directory number that identifies the adjacent
incoming office and is used in recording AMA
module 720 of the calling number. This option
is used if the LRN is not signalled. Exactly
10 digits must be datafilled.
