NCA-TSC Trunk Member
Identifies the trunk member whose D-channel will be used to route tandem 
NCA-TSCs or QSIG CISCs. Value range for this field is from 1 to the maximum 
number of members per trunk group supported on the switch.
Numbering Format
This field appears if the Send Calling Number field is 
y or r or the Send 
Connected Number field is 
y or r. This specifies the encoding of Numbering Plan 
Indicator for identification purposes in the Calling Number and/or Connected 
Number IEs, and in the QSIG Party Number. Valid entries are 
public, unknown, 
private, and unk-pvt. Public indicates that the number plan according to CCITT 
Recommendation E.164 is used and that the Type of Number is national. 
Unknown indicates the Numbering Plan Indicator is unknown and that the Type 
of Number is unknown. 
Private indicates the Numbering Plan Indicator is PNP 
and the Type of Number is determined from the ISDN Private-Numbering screen. 
An entry of 
unk-pvt also determines the Type of Number from the ISDN 
Private-Numbering screen, but the Numbering Plan Indicator is unknown.
Outgoing Channel ID Encodin
Appears only if the Group Type field is 
isdn, the Used for DCS field is y, and the 
Service Type field is anything except 
dmi-mos or sddn. Determines whether to 
encode the Channel ID IE as preferred or exclusive. Blank is not a valid entry. 
Defaults are determined as follows:
If the Group Type field is 
isdn and the Used for DCS field is y, default is 
exclusive.
If the Group Type field is 
isdn and the Used for DCS field is n, default is 
preferred.
If the Group Type field is not 
isdn or it is isdn, but the Used for DCS field does 
not appear, default is 
preferred.

Path Replacement Method
Appears when either the ISDN-PRI trunk or the ISDN-BRI trunk fields and the 
Basic Call Setup and Supplementary Services with Rerouting fields are set to 
y on 
the System-Parameters Customer-Options screen and when the Supplementary 
Service Protocol is either 
b or e and the Group Type field is isdn on the ISDN 
trunk group screen.
Replace Restricted Numbers
Appears when the Group Type field is 
isdn. Indicates whether to replace restricted 
numbers with administrable strings for incoming and outgoing calls assigned to 
the specified trunk group. This field applies to BRI and PRI trunks.
Replace Unavailable Numbers
Appears when the Group Type field is 
isdn. Indicates whether to replace 
unavailable numbers with administrable strings for incoming and outgoing calls 
assigned to the specified trunk group. This field applies to BRI and PRI trunks.
Send Called/Busy/Connected Number
This field appears only if the QSIG Value-Added Lucent field on the Trunk Group 
screen is 
y and the Group Type field is isdn. Specifies if the connected party’s 
number is sent on incoming or tandemed ISDN calls. Valid entries are 
y, n, or r 
(restricted). If set to 
y, the ISDN Numbering - Public/Unknown Format screen is 
accessed to construct the actual number sent, or the ISDN Numbering-Private 
screen (based on Numbering Format) is used. If set to 
r, the connected number is 
sent “presentation restricted.”
Valid entries Usage
better-route
Uses the most economical route, for example, the reconfigured 
call does not use the same trunk group as the original call.
alwaysAlways reconfigures the call regardless of the trunk group used.
Valid entries Usage
y/n
Enter y for the display to be replaced regardless of the service 
type of the trunk.
Valid entries Usage

Send Calling Number
Specifies whether the calling party’s number is sent on outgoing or tandemed 
ISDN calls. Valid entries are 
y, n, or r (restricted). If y is entered, the ISDN 
Numbering - Public/Unknown Format screen is accessed to construct the actual 
number to be sent, or the ISDN Numbering-Private screen (based on the 
Numbering Format field) is used. If the value is 
r, the calling number is sent 
“presentation restricted.” 
NOTE:
The ISDN Numbering - Public/Unknown Format screen can override the 
Send Calling Number field entry for any administrable block of extensions.
Send Codeset 6/7 LAI IE?
Specifies whether the ISDN trunk should transmit information in Codeset 6/7. If 
the UUI IE Treatment field is shared, then this field should be 
n. Otherwise, the 
same information will be sent twice and may exceed the message size. Default is 
y 
for pre-DEFINITY 6.3 compatibility.
Send Connected Number
Appears if the QSIG Value-Added Lucent field on the Trunk Group screen is 
n. 
Specifies if the connected party’s number is sent on incoming or tandemed ISDN 
calls. Valid entries are 
y, n, or r (restricted). If y is entered, the ISDN Numbering - 
Public/Unknown Format screen is accessed to construct the actual number sent, or 
the ISDN Numbering-Private screen (based on the Numbering Format field) is 
used. If the value is 
r, the connected number is sent “presentation restricted.”
NOTE:
The AT&T Switched Network Protocol does not support restricted displays 
of connected numbers. Therefore, if you administer the 1a 
country-protocol/protocol-version combination on the DS1 screen, you 
should not administer the Send Connected Number field to 
r (restricted) on 
the ISDN Trunk Group screen, as this causes display problems.
NOTE:
The ISDN Numbering - Public/Unknown Format screen overrides the Send 
Connected Number field entry for any administrable block of extensions.
Send Name
Specifies whether the calling/connected/called/busy party’s administered name is 
sent to the network on outgoing/incoming calls. Valid entries are 
y, n, or r 
(restricted). The value 
r indicates that the calling/connected name will be sent by 
the switch but will be marked “presentation restricted.” This value is valid only if 
the Supplementary Services Protocol field is 
a (national supplementary service), b

(for called/busy only) or d for the QSIG Global Networking Supplementary 
Services Protocol. When the Supplementary Service Protocol field is 
e (DCS with 
Rerouting), only values of 
y and n are permitted.
NOTE:
If name information is not administered for the calling station or the 
connected/called/busy station, the system sends the extension number in 
place of the name.
Send UCID
Specifies whether or not the trunk should transmit Universal Call IDs. The valid 
entries are 
y and n.
US NI Delayed Calling Name Update
Administrable if, on the System-Parameters Customer-Options screen, the 
ISDN-PRI field is 
y, and on the Trunk Group screen, the Carrier Medium field is 
either 
PRI/BRI or AT M, and the Supplementary Service Protocol field is a. This 
field provides display updates to the terminating phone for delayed calling party 
name provided by the network,
UUI IE Treatment
Specifies whether the user Information Element (IE) is shared. Enter 
shared if the 
trunk is connected to a DEFINITY 6.3 (or later) switch. Enter 
service-provider if 
the trunk is connected to a pre-DEFINITY 6.3 switch or service provider 
functionality is desired.
Wideband Support
Specifies whether Wideband Switching is supported by this trunk group. Valid 
entries are 
y or n. For ISDN trunk groups containing ISDN-BRI interfaces, the 
only valid entry is 
n. Otherwise you can administer this field only if the Wideband

If calling name information is received after the incoming call 
has been delivered to the terminating phone, there is a display 
update.
NOTE:
BRI trunks do not support this value.
nIf calling name information is received after the incoming call 
has been delivered to the called phone, there is no display 
update to the terminating phone.

Switching field is y on the System-Parameters Customer-Options screen. If set to 
y, the Wideband Support Options page appears. All trunk members must be from 
TN464C (or later) circuit packs.
NOTE:
Wideband trunk calls are treated as a single trunk call when Automatic 
Circuit Assurance (ACA) measurements are taken. This way, if an ACA 
referral call is generated (for short or long holding time), the wideband call 
only triggers a single referral call using the lowest B-channel trunk member 
associated with the wideband channel.
Field descriptions for the Shared UUI Feature 
Priorities page
The fields in this page show the priorities for each type of information to be 
forwarded in the Shared UUI. This page appears only on the ISDN trunk group 
screen when all of the following conditions are met:
nThe UUI IE Treatment field is shared.
nThe Supplementary Service Protocol field is set to anything except b.
Screen 116. Shared UUI Feature Priorities
Changing the priorities in this screen may affect whether certain information will 
be sent. For more information about setting priorities, refer to “Information 
Forwarding” in DEFINITY ECS Guide to ACD Call Centers. These fields are 
unique to the ISDN trunk group screen.

Field descriptions for the Incoming Call 
Handling Treatment page
Screen 117. Incoming Call Handling Treatment
NOTE:
This page does not appear if the Digit Handling (in/out) field is overlap on 
the “in” side or if the Direction field is 
outgoing.
The Incoming Call Handling Treatment page can (optionally) provide unique call 
treatment for different incoming calls on any ISDN trunk group. The number of 
unique treatments that can be specified in this table and the number of pages vary 
depending on whether the Usage Allocation Enhancements feature is enabled and 
on the amount of available system memory. 
Unique digit manipulation capabilities, CPN/BN requests, and night service 
destinations are possible for different types of incoming calls. The unique digit 
manipulation capabilities can be particularly useful to accommodate different dial 
plans for different services on an ISDN trunk type with a Service Type (field 
entry) of 
cbc (Call-by-Call). The table can also be used for ISDN trunk groups 
that are not Call-by-Call. For example, an ISDN group with Service Type set to 
mega800 could use the Incoming Call Handling Treatment table to distinguish 
treatment of calls to different 800 numbers based on the Dialed Number 
Identification Service (DNIS) number that is incoming to the switch.

Each row in the table consists of seven columns. The first three columns 
(Service/Feature, Called Len, and Called Number) constitute a key that together 
select which row or unique treatment should apply for an incoming call on the 
group. The remaining four columns (Del, Insert, and so on) specify the treatment 
to be provided for a call that matches the key.
If an incoming call is for a service listed in a row on the table, 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 matches 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 does exist with the same service and number length, then the Called 
Number field will be 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 has been determined. 
Together, the Del and Insert fields can be used to manipulate the incoming number 
that will be used to route the call. The Per Call CPN/BN field can be used to 
request CPN/BN 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.
The Incoming Call Handling Treatment Table always automatically rearranges to 
show the precedence order the system uses to pick an entry. Thus, you can easily 
predict the behavior of the Incoming Call Handling Treatment Table by noting the 
order in which the entries display. (The entries rearrange after submitting the trunk 
group screen. A subsequent change trunk-group or display trunk-group command 
then shows the rearranged order.)
DEFINITY ECS traverses the table from top to bottom and picks the first entry 
that matches all the following criteria:
nThe Service /Feature, if applicable, matches
nThe Called/Length matches
nThe Called Number matches
If the administered Called Length or Called Number is blank, that criterion is 
considered successful.

Incoming Call Handling Treatment Table entries with a predefined service/feature 
always appear before entries with a user-defined service/feature. To control the 
order in which certain entries appear, you must use user-defined services/features 
for those entries. For example, you can redefine the predefined mega800 
service/feature as an identical user-defined entry with the name m800.
User-defined entries are always listed in the reverse order compared to the way 
they appear on the ISDN Network-Facilities screen. See ‘‘
Packet Gateway Board’’ 
on page 846. Thus, given two user-defined services/features ABC and XYZ, you 
can force XYZ to appear before ABC in an Incoming Call Handling Treatment 
Table by putting XYZ after ABC on the Network-Facilities screen.
NOTE:
DCS features that use the remote-tgs button (on the remote switch) do not 
work when the local trunk group deletes or inserts digits on the incoming 
call. These buttons try to dial a local TAC. Adding or deleting digits defeats 
this operation and renders the remote feature inoperable. If digit 
manipulation is needed, use it on the outgoing side, based on the routing 
pattern. One reason for digit manipulation is insertion of the AAR feature 
access code (FAC).
These fields are located on the Incoming Call Handling Treatment Table screen.
Service/Feature
Specifies the ISDN Services/Features for an incoming call type. See the Service 
Type field description for a list of predefined Services/Features that can be 
received. Or, use Type 0, Type 1, and Type 2 user defined services. The identifier 
other can be used for any Services/Features not explicitly specified.
Called Len
Specifies the number of digits received for an incoming call. A blank entry is used 
as a “wild card” entry and, when used, means that any length of digits associated 
with the specified Service/Feature can match in this field. Valid entries are 
0 to 21, 
or leave blank.
Called Number
Specifies the leading digits received for an incoming call. A blank entry is used as 
a “wild card” entry and, when used, means that any number associated with the 
specified Service/Feature can match in this field. Valid entries are 
1 to 16, or leave 
blank.

Del
Specifies the number of leading digits to be deleted from the incoming Called 
Party Number. Calls of a particular type may be administered to be routed to a 
single destination by deleting all incoming digits and then administering the Insert 
field with the desired extension. Valid entries are 
1 to 21, all, or leave blank.
Insert
Specifies the digits to be prepended to the front of the remaining digits after any 
(optional) digit deletion has been performed. The resultant number formed from 
digit deletion/insertion is used to route the call, provided night service is not in 
effect. Valid entries are up to 16 characters consisting of a combination from the 
following: 
0 to 9, *, #, or leave blank.
Per Call CPN/BN
Specifies when and how to request Calling Party Number (CPN) or Billing 
Number (BN) for calls of this type. Leave blank when connected to another 
switch, or when connected to a public network outside North America. Within 
North America, leave blank when connected to a public network that does not 
permit customer equipment to request CPN or BN for individual incoming calls. 
The AT&T Switched Network offers this service under the titles “CPN/BN to 
Terminating End on a Per-Call Basis” and “ANI (BN) on Request.” An entry of 
none indicates the switch will not request either CPN or BN for any incoming 
calls of this type. Valid entries are 
cpn-only, bn-only, bn-pref (prefer BN, but 
accepts CPN), 
cpn-pref (prefer CPN, but accepts BN), none, or leave blank. 
Leave blank when connected to another switch or to a network other than the 
AT&T Switched Network.
NOTE:
A 4-second delay occurs in terminating the call to the far-end station if the 
connecting switch does not respond to the request.
Night Serv
Specifies a night service extension (can be a VDN extension) per Service/Feature. 
An entry other than blank overrides Night Service entry on page 1 of the screen. 
This entry can be overridden by the Trunk/Member Night Service entry when 
provided. Valid entries are an assigned extension, the attendant group access code 
(
attd), or leave blank.
