Design Considerations
ISDN-BRI and ISDN-PRI interfaces cannot be mixed in the same trunk group.
Therefore, consider the following:
nThe earliest trunk member (the lowest numbered one) administered is
considered correct.
nIf an offending member is subsequently found (meaning the first member
was BRI and a later member was PRI, or vice versa), the cursor positions
on the offending member, and the following error message appears:
Cannot mix BRI and PRI ports in the same trunk group.
Field descriptions for page 1
Many of the fields on the following screens are described in ‘‘
Trunk Group’’ on
page 980. If a field on this screen is unique, it is listed and defined.
Screen 113. ISDN Trunk Group screen
The Calling Number – Delete, Insert, and Numbering Format fields are the
administrable fields for the Calling Line Identification Prefix feature. They appear
when the Direction field is incoming or two-way.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 758 ISDN trunk group 17 Calling Number – Delete Calling Number – Insert Calling Number – Numbering Format This field indicates the TON/NPI encoding applied to CPN information modified by the CLI Prefix feature. This encoding does not apply to calls originating locally. The Numbering Format field on page 2 of this screen applies to calls originated from this switch. If this field is blank, DEFINITY ECS passes on the encoding received in the incoming setup message. If the incoming setup message did not contain CPN information and digits are added, the outgoing message will contain these digits. If the Numbering Format field is blank in this case, the value defaults to pub-unk. If the Numbering Format field on page 2 of this screen is also administered as unknown, the trunk group is modified to “unk-unk” encoding of the TON/NPI. Therefore, this field also must contain a value other than unknown. NOTE: The values for this field map to the Type of Numbering (TON) and Numbering Plan Identifier (NPI) values shown below. Valid entries Usage 1 to 15Enter the number of digits, if any, to delete from the calling party number for all incoming calls on this trunk group. all blank Valid entries Usage 1 to 15Enter the specific digits, if any, to add to the beginning of the digit string of incoming calls when the calling party is a member of this trunk group. blank Valid entriesType of numbering (TON) Numbering plan identifier (NPI) blank incoming TON unmodifiedincoming NPI unmodified natl-pubnational(2) E.164(1) intl-pubinternational(1) E.164(1) locl-publocal/subscriber(4) E.164(1) pub-unkunknown(0) E.164(1)
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 759 ISDN trunk group 17 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. lev0-pvtlocal(4) Private Numbering Plan - PNP(9) lev1-pvtRegional Level 1(2) Private Numbering Plan - PNP(9) lev2-pvtRegional Level 2(1) Private Numbering Plan - PNP(9) unk-unkunknown(0) unknown(0) Valid entries Usage AT M The trunk is implemented via the ATM Interface circuit pack.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 760 ISDN trunk group 17 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. Valid entries Usage 0 CCITT 6Any other than CCITT or System 85 R2V4, 4E11 7System 85 R2V4, 4E11 Valid entries Usage 6 Other types. 7System 85 R2V4, 4E11, or newer switch types
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 761 ISDN trunk group 17 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 762 ISDN trunk group 17 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. The following table indicates the expected ISDN-PRI message size from several Lucent Technologies products. QSIG Value-Added Lucent Provides QSIG-VALU services. This field appears only if the Value-Added Lucent (VALU) field on the System-Parameters Customer-Options screen is y. This field can be set to y only if the Supplementary Service Protocol field on the System-Parameters Customer-Options screen is b. Valid entries are y and n. Blank is not a valid entry. Service Type Indicates the service for which this trunk group is dedicated. The following table provides a listing of predefined entries. In addition to the Services/Features listed in this table, any user-defined Facility Type of 0 (feature) or 1 (service) on the Network Facilities screen is allowed. Up to 10 (G3si, G3csi) or 200 (G3r) ISDN trunk groups can have this field administered as cbc.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 765 ISDN trunk group 17 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 Type’’ on page 762, excluding sddn or any new Facility Type of 0 (feature), 1 (service), or 3 (outgoing) that is defined by users on the Network Specific Facility Encoding screen. Trunk Hunt The switch performs a trunk hunt when searching for available channels within a 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).
