Carrier Medium
This field lets you to specify the type of transport medium interface used for the 
ISDN trunk group. Appears only when the Group Type field is 
isdn and, on the 
System-Parameters Customer-Options screen, either the Async. Transfer Mode 
(ATM) Trunking or H.323 field is 
y.
Charge Advice
Use this field to accumulate and access charge information about a call. You 
already must have set the CDR Reports field to 
y or r (ring-intvl) before changing 
this field from its default of none. Remember that receiving Advice of Charge 
during the call (administered as “automatic” or “during-on-request”) affects 
system performance because of the increased ISDN message activity on the 
signaling channel, which may reduce the maximum call capacity.

Codeset to Send Display
This field defines the codeset for sending the information element for Display. 
The value depends on the type of switch to which the user is connected.
Codeset to Send National IEs
This field defines the codeset for sending the information element (IE) for national 
IEs. National IEs include all IEs previously sent only in code set 6 (such as DCS 
IE). Now these national IEs, including Traveling Class Marks (TCMs) and 
Lookahead Interflow (LAI), can be sent in code set 6 or 7. The value depends on 
the type of switch the user is connected to.
NOTE:
A Traveling Class Mark (that is, the user’s FRL or the user’s trunk group 
FRL) is passed between tandem nodes in an ETN in the setup message only 
when the Service Type field is 
tandem. It then is used by the distant tandem 
switch to permit access to facilities consistent with the originating user’s 
privileges.
Valid entries Usage
none
Enter none if you do not want the system to collect Advice of 
Charge information for this trunk group.
automaticEnter automatic only if your public network sends Advice of 
Charge information automatically.
end-on-
request Enter end-on-request if DEFINITY ECS must request charge 
information with each call, and you want to receive only the 
final call charge.
during-on-
request Enter during-on-request if DEFINITY ECS must request 
charge information with each call, and you want charges to 
display during and at the end of a call.

Digit Handling (in/out)
This field defines whether overlap receiving and overlap sending features are 
enabled. Set the field to 
overlap when you want overlap receiving or overlap 
sending. Set to 
enbloc when you do not want these features enabled. The first 
field value indicates digit receiving and the second value indicates digit sending. 
There are 4 possible combinations:
 enbloc/enbloc, enbloc/overlap, 
overlap/enbloc, and overlap/overlap.
Without overlap receiving or sending enabled, the digits on incoming and 
outgoing calls are sent enbloc. If the Digit Handling field is 
overlap/enbloc or 
overlap/overlap, the following results:
— Incoming Call Handling Treatment table does not appear 
— The Digit Treatment and Digits fields appear
— Warning message indicates that all Incoming Call Handling entries are 
removed when screen is submitted
— When screen is submitted with these values, all Incoming Call Handling 
entries are removed
Far End Test Line No.
Specifies the number sent to the far-end’s ISDN test line extension. When the test 
trunk long command is issued, this exact number is sent to the far-end to establish 
a call that tests the integrity of the trunk member under test. The number does not 
pass through routing or undergo digit manipulation. The digits entered must be 
what the far-end expects. For example, for an ISDN tandem trunk, the far-end test 
number should be a 7-digit ETN (Electronic Tandem Network) number. Up to 15 
digits may be entered in this field.
Max Message Size to Send
Defines the maximum size of ISDN messages sent by the switch. Currently, the 
system can receive 260 byte messages. Valid entries are 
128, 244, 256, and 260.

Test Call BCC
Indicates the Bearer Capability Code (BCC) used for the ISDN test call.
Testcall ITC
Controls the encoding of the Information Transfer Capability (ITC) codepoint of 
the bearer capability IE in the SETUP message when generating an ISDN test call. 
Allowed values are 
rest (restricted) and unre (unrestricted).
NOTE:
ISDN Testcall feature has no routing, so a testcall is never blocked 
due to an incompatible ITC.
Testcall Service
Specifies the call-by-call selection for an ISDN test call. Only appears if the 
Service Type field is cbc. Valid entries are all of the services listed in ‘‘
Service

(service), or 3 (outgoing) that is defined by users on the Network Specific Facility 
Encoding screen.
Trunk Hunt

facility in an ISDN trunk group. Enter 
ascend to enable a linear trunk hunt search 
from the lowest to highest numbered channels, or 
descend for a linear trunk hunt 
search from the highest to lowest numbered channels. With both 
ascend and 
descend, all trunks within an ISDN trunk group are selected based on this field 
and without regard to the order in which trunks are administered within the trunk 
group.
Enter 
cyclical to enable a circular trunk hunt based on the sequence the trunks 
were administered within the trunk group. When using ISDN-BRI interfaces, only 
cyclical is allowed.

NOTE:
The cyclical option cannot be set if the trunk group using ISDN-PRI 
interfaces is to be used for Wideband operations (the Wideband Support 
field set to 
y).
The search can be administered per ISDN-PRI trunk group, but it infers the 
direction of search within all ISDN-PRI facilities (or portions of those facilities) 
administered within the trunk group.
Usage Alloc
Appears when the Service Type field is 
cbc. Specifies whether users want to 
allocate the services provided by the trunk group. Valid entries are 
y and n. If y is 
entered, two additional CBC-related screens display. They are the CBC Trunk 
Group Usage Allocation Plans screen and the CBC Trunk Group Usage 
Allocation Plan Assignment Schedule.

BSR Reply-best DISC Cause Value
Switches that are polled as resources in a Best Service Routing application return 
data to the polling switch in the ISDN DISC message. Since some cause values do 
not work over some networks, this field sets the cause value that your switch will 
return in response to a BSR status poll. If this field is set incorrectly, incoming 
status poll calls over this trunk group will be dropped before any data is returned 
to the polling switch. This field only appears if the UUI IE Treatment field is set to 
shared.
!CAUTION:
In most cases, this field will be set to the appropriate value during 
installation. If you need to change it, your network service provider should 
be able to help you choose an appropriate value. Don’t change this field 
without the assistance of Lucent or your network service provider.

DCS Signaling
Specifies the means used to send the DCS message. This field only appears if the 
Used for DCS field entry is 
y and the Service Type field is anything except 
dmi-mos or sddn. Valid entries are bx.25 for the traditional DCS feature or 
d-chan for the DCS over ISDN-PRI D-channel feature. 
DCS over D-channel is not supported on trunk groups containing ISDN-BRI 
interfaces.
nHop Dgt — The Tandem Hop Limitation and QSIG Additional Network 
Feature Transit Counter (ANF-TC) features provide a counter that reflects 
the number of switches (that is, the number of hops) that a call has gone 
through. The counter increments as a call leaves DEFINITY ECS using 
tandem facilities. Valid values are 
y and n. One or both of the features can 
be applied to the trunk group depending on the following:
— If you enter 
y and the Group Type field is tandem or the Group 
Type field is 
isdn and the  Service Type field is tandem, the Tandem 
Hop Limitation feature is applied to the trunk group.
— If you enter 
y and you set the Group Type field to isdn, set the 
Service Type field to 
access, dmi-mos, public-ntwrk, tandem, tie, 
or any of the craft-defined services allowed in the field. Set the 
Supplementary Service Protocol field to 
b or d, then the ANF-TC 
feature is applied to calls on the trunk group.
NOTE:
The above conditions overlap. If the Group Type field is isdn, 
the Service Type field is 
tandem, and the Supplementary 
Service Protocol field is 
b or d, then both the Tandem Hop 
Limitation and ANF-TC features are applied to calls on the 
trunk group.
— If both features are applied to calls on the trunk group, ANF-TC 
takes precedence. In situations where DEFINITY ECS is an 
Incoming or Outgoing Gateway, either feature uses the hop count 
and transit information provided by the other.
Maximum Size of UUI IE Contents
This field appears when the UUI Treatment field is shared. Enter the maximum 
number of bytes of user information that the network supports.
