1When only rotary pulses are received via the trunk group
When either rotary pulses or tough-tone can be accepted
NOTE: The ISDN-PRI applications use the D-channel to transmit and receive
dialed digits. Dialed digits are transmitted as ASCII characters. Therefore, for
ISDN applications, this field is ignored; either option may be translated.½
Assigns the trunk group to CDR record keeping. Field encodes and their descriptions
are:½
0 Trunk group usage not applicable for CDR recording½
1 Trunk group usage will be recorded by CDR½
2 Trunk group usage will be recorded, account code is required
Not used for ISDN applications.
This field is only applicable when CDR is being used, and then only to change the
default CDR timer value. Field encodes represent intervals in l-second increments.
The range is 1 through 99 with dash (–) being the default timer value of 6 seconds.½
Administers the optional transmission loss assignments. The encode translated depends
on the network configuration and service application. However, the default (0) setting
should always be used unless an NEC engineer is consulted. (Chapter 4, The Digital
Loss Plan, describes the digital loss plan and table 4-2, Digital Loss Plan (Port-to-Port
Losses), in this same chapter lists port-to-port loss values.)½

Field 15Advanced Private Line Termination (APLT) services are not applicable in the ISDN-
PRI environment. Therefore, for trunk groups using ISDN-PRI facilities, this field is
ignored. Refer to Appendix C, Administrative Procedure Summary, for more
information about the dynamic 120 trunk types.½
Field encodes and their descriptions are:
0 When APLT services are not available for analog or DS1/DMI-BOS facilities
1 When APLT services are available for analog or DS1/DMI-BOS facilities.
Field 16
Assigns whether disconnect supervision is (1) or is not (0) provided.
NOTE: The ISDN-PRI protocol provides disconnect supervision. Therefore, this
field is ignored by ISDN software.
Field 17
V4 Only
Assigns whether the trunk group may be used to support modem pool calls. Field
encodes and their descriptions are:
0 When AVD is not provided (that is, insert a modem). This includes voice and
digital data. This option is required for all trunk groups that support modem pool
calls including voice and digital data.
1 When the AVD option is provided (that is, do not insert a modem).
Procedure 103 Word 1: Trunk Group Digit Collection and Trunk-Side BC

Field 1
Displays the trunk group number previously administered in procedures 100 and 101.
Fields 2-13
DS1 or ISDN-PRI do not place any new or additional considerations on translating
these fields. The encodes that are translated are generally dependent on each trunk
group, its application, and the associated trunk groups. Refer to Appendix C,
Administrative Procedure Summary, for more information about the dynamic 120 trunk
types. For more information see Dynamic Trunk Type in Procedure 100 Word 1.
Field 14
Specifies how the dialed digits are outpulsed. Field encodes and their descriptions are:
0
1When digit outpulsing may overlap digit reception
When all digits must be received before outpulsing may start. All ISDN
applications, regardless of the trunk type, require that a (1) be translated in this
field. Digit outpulsing does not begin until all digits are received. Then digits are
outpulsed as ASCII characters — per the ISDN recommendations.

Field 15V4 Only
Used for non-ISDN trunk groups that interwork to ISDN trunk groups. Therefore,
field 15 only applies to non-ISDN trunk groups. Generally, trunk groups can use both
analog and ISDN-PRI (digital) transmission facilities. Any restrictions and
compatibility requirements are conveyed as information known as the BC code. This
field is used to populate the BC IE. Field encodes and their descriptions are:½
0 Voice and Voice-grade data
1 Mode 1 data (56K-bps)
2 Mode 2 data (subrate up to 19.2K-bps)
3 Mode 3 data (also called packet mode)
4 Mode 0 data (64K-bps digital data)
Procedure 116 Word 1: DS1/DMI/ISDN-PRI Trunk Assignments
Each analog trunk circuit pack provides four circuits that are administered by using procedure 150.
Conversely, each DS1 provides 24 circuits (channels) that are administered by using procedure 116.
Figure 7-15, Procedure 116 Word 1: DS1 Trunk Assignments to Equipment/Circuit Location (System 85
R2V4), depicts procedure 116, word 1. Each DS1/MFAT carrier will support a maximum of two DS1s,
each occupying one slot and located in slots 5 and 18. When a DS1/DMI/ISDN interface (trunk
applications) is located in slot 5, it uses the six slots 0, 1, 2, 5, 6, and 7. When the interface is located
in slot 18, it uses the six slots 13, 14, 15, 18, 19, and 20.½

The DS1 channels are assigned to slot and circuit locations according to the order in which the module
processor scans the equipment carrier. The first circuit scanned is circuit 0 of slot 05 (or 18); the second
is circuit 0 of slot 06 (or 19); the third is circuit 0 of slot 7 (or 20); and the fourth is circuit 1 of slot 05
(or 18). Continue in this way to channel 12 that will be located at circuit 3 of slot 07 (or 20); remaining
12 channels are assigned beginning with circuit 0 of slot 0 (or 13). Continue in this way through
channels 23 or 24, depending on whether robbed-bit or 24th-channel signaling is translated; refer to table
7-3, DS1/ISDN-PRI Administration — Channel Versus Trunk Assignments.

NOTE: Channel 24 is the D-channel.½
NOTE: When the equipment carrier is configured with two DS1s, physical slots 3, 8, 16, and 21
are available for other applications. If only one DS1 is configured, then six additional slots are
available for other applications.
To minimize confusion and eliminate the need for maintaining elaborate trunk to channel cross-reference
tables, trunk group member assignments should match the DS1 channel assignments (for example, trunk
group member 1 should be on channel 1). When using procedure 116, word 1, refer to Table 7-2,
Trunks Supporting Signaling Type 20, to determine which slot and circuit to translate for channel 1.
Repeat this procedure by sequentially selecting DS1 channels (2, 3, and so on) and translating the
appropriate slot and circuits as required.
Fields 1-5
These fields are used to translate the equipment location, including slot and circuit
(channel) location, and to associate the equipment location (channel) with the particular
trunk group translated in field 6.
Field 6
Translates the trunk group. Permitted encodes must be numbers with the range of 18
through 999.
Field 7
Translates a particular number that functions as the night service number. The number
of digits depend on the particular application and its numbering plan.

Field 8Disables a channel’s signaling. Field encodes and their descriptions are:
- (Dash) used when ISDN is enabled.
0 Used when signaling is enabled. This is the default option (not used with ISDN).
1 Used when signaling is disabled. Use this with dedicated switched connection to
disable signaling for a tie trunk. The signaling bit then can be used as a data bit,
allowing the full 64K-bps to be used for data.
Field 9Not applicable for ISDN-PRI.
Field 10For outgoing AAR and TVS test calls, this field determines the encoding of the called
party IE as assigned in procedure 107, word 1, and procedure 108, word 1. If the
B-channel is in an ISDN dynamic trunk group, this field also determines how an
incoming call over the trunk is processed (see the Procedure 100 Word 1 section
earlier in this chapter).½
See Appendix C, Administrative Procedure Summary, for a discussion of the called
party IE and the Procedure 107 Word 1 and Procedure 108 Word 1 sections in this
chapter for more information. Field encodes and their descriptions are:
0 For another customer premises switch
1 For a private network connection to a host computer
2 For public network connections
Procedure 012 Word 1: Name Database
The name database is used by those features (such as DCS, ISDN-PRI) which provide display type
information to voice terminals. Some examples of the more common display information include;
calling party name, vector directory number, and trunk group name. For ISDN-PRI applications, the
name database information is used to populate the display IE in the call setup and connect messages.
Figure 7-16, Procedure 012 Word 1: Name Database Establish Key (System 85 R2V4), depicts the first
of three related procedures.½

Field 4The main function of this field is to provide some administration control over what is
displayed on the voice terminals digital display. Field encodes and their descriptions
are:
-
(Dash) for all incoming only trunk groups.
0
Used when the user (extension) does not want the outgoing trunk group name
displayed but does desire the dialed number to remain on the display.
1
Used when the user desires to display the name of the outgoing trunk group (such
as ISDN/SDN, MEGACOM, or CBC).
NOTE: For a tandem interworking call, the name of the incoming trunk
group is transmitted in the display IE of the ISDN-PRI outgoing trunk group.
Field 5The method that defines the name. Field encodes and their descriptions are:
0
Used for adding a new name or changing an existing name; requires that the name
change be made with word 2.
1
Used for copying the name from the extension or trunk group that is displayed in
field 6
Field 6This field is used with field 5 to copy an existing name to the extension or trunk group
identified in field 1. Field encodes and their descriptions are:
l   000 through 99999, for extension and directory numbers
NOTE: Whether the number is three, four, or five digits depends on the
numbering plan.
l   18 through 999, for trunk group numbers
