Lucent Technologies Release 8.2 Trunk Group for Channel Selection, Supplementary Service Protocol

Networking Screens A Screens Reference

Trunk Group for Channel Selection

Enter the assigned trunk group number. (An ISDN-BRI trunk group may not be used.)

Valid entries Usage

1to 99. blank

Supplementary Service Protocol

Determines whether AT&T NCA TSCs or QSIG NCA TSCs are sent over the interface. To change this field from a to b, first check the Adm’d NCA TSC Index field on the ISDN TSC Gateway Channel Assignments (page 291). Make sure no NCA TSC on the Signaling Group screen is administered as a Gateway Channel. If they are, you must remove the NCA TSC Gateway assignment first before this field can be changed to b.

Valid entries	Usage
a	AT&T protocol
b	QSIG protocol. This field may be set to b only if the Basic
	Supplementary Services field on the System-Parameters
	Customer-Options screen is y. If this field is b, pages 2 through
	5 do not appear.

Trunk Brd

Enter a 5-character DS1 Interface circuit pack number that has trunk members belonging to this Signaling Group. Displays when the Associated Signaling field is n (indicates NFAS).

Valid entries	Usage
01 through 44 (G3r)	First and second characters are the cabinet
01 through 03 (G3si)	number
A through E	Third character is the carrier
01 through 20	Fourth and fifth characters are the slot number
blank

Interface ID

In an NFAS Signaling Group, an Interface ID must be assigned to each DS1 facility so that it can be referenced by both interfacing switches. When a call is established between switches, the Interface ID at each end is used to determine which B-channel is to be used to establish the call. The Interface ID numbers on both ends must be the same. Displays when the Associated Signaling field is n (indicates NFAS). Enter an interface ID for the corresponding DS1 Interface circuit pack.Pages 2 through 5 of the screen.
