Group MemberA trunk group member is an individual trunk associated with
Assignmentsa single port on the TN767. Refer to the Port Assignments
Record to assign individual trunks to this trunk group. Enter
the port location in the Port field. Enter the trunk group
members name in the Name field. The name can be up to
ten-characters. A good practice to follow here is to use the
circuit identification from the local exchange as the member
name. If you have problems in the T1 pipe, having this
identification will allow the T1 facility providers to
troubleshoot the circuit faster.
The 
TRUNK GROUP screen fields in table E-8, Trunk Group Screen Settings - Page 2 - Incoming Call
Handling Table — Generic 1, comprise an incoming call handling table. The table consists of up to 12
rows of seven columns per row. The first three columns constitute a key that together select which row
or unique treatment should apply for an incoming call on the group. The remaining four columns
specify the treatment to be provided for a call that matches the key.
The first column or field of the key is the Service/Feature field. If an incoming call is for a
service listed in a row in the incoming call handling table (see table E-8), then that row may specify the
treatment for the call, depending on the other two columns of the key. The Called Len field is used
to continue the row determination. If the number of digits received with the incoming call match the
number of digits in the Called Len field for calls to the matched service, then this row may apply.
If no other row also contains a matching service and called length, then this row does apply. If another
row exists with the same service and number length, then the Called Number field is used to
continue the row determination. If the leading digits received with the incoming call match the digits
specified in the Called Number field, then this row applies to the call. Therefore, with this table, a
unique treatment can be given to any incoming call, even if these calls are to the same service or have
the same length of digits. The remaining four fields specify the unique treatment for the call once the
row is determined. Together, the Del and Insert fields are used to manipulate the incoming number

that routes the call. The Per Call SID/ANI field can be used to request SID/ANI only for specific
calls incoming on the group. The Night Serv field is used to have calls of different types routed to
different night destinations when night service is in effect.
This table is generally used when a Generic 1 is connected to the public network with several different
services (such as MEGACOM® 800 service and ACCUNET® Switched Digital Services) but also has
private network applications.
NOTE: Administering this table is optional.

FIELD
SETTING
REMARKS
Service/FeatureTandemThis field must match the Service Type field on the first
page of the 
TRUNK GROUP screen. For connections to a
System 85 R2V4, this field should be tandem if TCMs are
sent or tie if TCMs are not sent.
Called LenEnter the number of incoming digits expected. If the service
type is tandem, 7 or 10 digits are expected.
Called NumberThis field allows you to specify the leading digits on
incoming calls that you want to match.
DelEnter the number of leading digits you want deleted. This
field combined with the next field allows you to treat calls
that match the leading digits in special ways. These fields are
analogous to the DID Additional Digit and
AAR/ARS Prefix Digit fields in procedures 101 and
103 in System 85 R2V4.
InsertEnter the digits to be inserted in this field.
Per Call SID/ANIThis field only applies to ISDN-PRI connections to the public
network. Leave it blank.
Night Serv.Enter an extension to which you want calls routed after hours.
This field allows you to specify different night service
destinations for different rows (types of calls) in the table.
Dial Plan Screens Settings
You must set up a dial plan that allows you to originate or tandem calls to and to receive calls from a
System 85 R2V4. Since many ways exist to do this, this appendix does not cover the details of how to
set up the dial plan. For consistency and troubleshooting purposes, the dial plan implementation on the
Generic 1 should match that of the System 85 R2V4. For example, if a System 85 R2V4 uses AAR-only
with a 4-digit dial plan, then so should the Generic 1.

Routing Patter Screen Settings
This screen is used to build the routing patterns for ISDN-PRI calls made to a System 85 R2V4. The
patterns are selected using the HNPA, FNPA, RHNPA, and RNX tables. The only ISDN-PRI-specific
fields in this screen are the IXC, BCC value, and Service/Feature fields. The BCC value
fields can be used to route calls based on their ISDN BCs and low-layer compatibilities, such as voice
versus mode 1 digital data. The subnet trunking feature is also present in this screen in the No. Del
Digits and Inserted Digits fields.
Following is an example of this screen when a Generic 1 is connected to a System 85 R2V4 via ISDN-
PRI tie trunks:

Table E-9, Routing Pattern Screen Settings — Generic 1, describes the ISDN-PRI-specific settings for
this administration screen. For information on how to set the other fields, see DEFINITY® 75/85

FIELD
SETTINGREMARKS
IXCLeave this field blank for this application. 101288 is the
interexchange (long distance) carrier code for AT&T. Since
this is a private network, this field does not apply.
BCC ValueThis is where Generalized Route Selection (GRS) is
implemented.
If you want only certain types of calls to be routed to specific
trunk groups, enter a y for those types of calls in the desired
preference. Enter n for those types of calls you do not want
routed over that trunk group. For example, if you want only
mode 0 calls (64K-bps raw data) routed only on the trunk
group in the second preference, you would enter a y in the
second preference under BCC value 4 and n for every other
field in the BCC 4 column. If another type of call tries to go
out over that trunk group, it will skip to the next preference.
For further details of how to route calls using GRS, see the
Bearer Capability section in chapter 1, Introduction.
Service/FeatureLeave this field blank. It applies to network services such as
MEGACOM® service or WATS. Since this is a private
network, this field does not apply.
SID Prefix Table Screen Settings
This screen allows you to decide which extensions will be used to send calling party and/or connected
number. This feature is called ISDN-PRI Call Identification in Generic 1 terminology. For more details,
see DEFINITY® 75/85 Communications System, Generic 1 and System 75 Feature Description, Issue 5,
February 1989, 555-200-201. Refer to the section titled Integrated Services Digital Network Primary
Rate Interface. Also refer to DEFINITY® 75/85 Communications System, Generic 1 and System 75
Implementation, Issue 1, February 1989, 555-204-654. See page 4-57.
The 
TRUNK GROUP screen must also be administered to send call identification information.
Following is an example of typical settings for this screen when a Generic 1 is connected to a System 85
R2V4 via ISDN-PRI tie trunks:

REMARKS
Ext LenThis field and the next constitute a key that determines which
row of the table to apply to a call. Enter the number of
extension digits in the dial plan. For example, if you are on a
five digit dial plan, enter 5. You can also use this table if
you have a mixed numbering plan.
Ext CodeThis field allows groups of extensions to be administered. If
12 is entered here, for example, and 5 was administered in
the first field, then all extensions of the form 12XXX will
match this row. If 12 is administered here and 123 is also
administered, then all numbers of the form 12XXX except for
123XX will match this row. For example, if you wanted all
extensions of the form 12XXX except for 123XX to be sent
with the SID prefix 30346 and the 123XX extensions to be
sent with the SID prefix 30353, then you would administer
both 12 and 123 in this field in two different rows.

SETTINGREMARKS
Enter the digits you add to the extension code digits to form a
10-digit SID number. For example, in the sample screen
shown above, if any extension of the form 65XXX places or
answers a call, the number sent to a System 85 on the far end
will be 619-486-5XXX. In the example, the other numbers
that would be sent are 619-496-6XXX, 619-496-7XXX, 619-
496-8XXX.
Terminating Extension Group Screen Settings
The only field on this screen applicable to ISDN-PRI is the ISDN Caller Display field. You
must enter either grp-name or mbr-name to specify whether the TEG group name or member name
is sent to the originating user when a member of a TEG answers.
Hunt Group Screen Settings
The only field on this screen applicable to ISDN-PRI is the ISDN Caller Display field. You
must enter either grp-name or mbr-name to specify whether the hunt group name or member name
is sent to the far end when a member of a hunt group answers.
