2. Enter set trunk-group-chan-select tgnum to specify the trunk-group
number that accepts incoming calls where the Information Channel Selection field
does not specify a preferred channel for bearer transport.
This is useful if the signaling group controls more than one trunk group (in cases
where you wish to manage a DS1 facility with more than one trunk group).
3. Enter set primary-dchannel circuit-number, where circuit-number is
an identifier for a Branch Gateway, slot, or T1/E1 circuit, to select the primary D-
channel number.
For the value of circuit-number, you can use a 3-digit Branch Gateway identifier
(for example, 005), a 2-character slot identifier (for example, v2), or a 2-digit circuit
number (24 for T1-ISDN, 16 for E1-ISDN).
4. If your trunk is provisioned without a D-channel for signaling, enter set
associated-signaling no to use Non-Facility Associated Signaling (NFAS).
Note:
NFAS is primarily a feature for ISDN-T1 connections offered by service providers
in North America and Hong Kong. However, it can also be used on private-
network connections, and in that context it is possible to set up NFAS using ISDN-
E1 interfaces. If you are using NFAS, enter add nfas-interface gateway
module interface-id, where gateway is the 3-digit Branch Gateway
identifier, module is the 2-character slot identifier, and interface-id is the
DS1 circuit number associated with the NFAS group. The value of interface-
id is received from the network service provider.
Note:
The North American Public Network Service Providers do not allow any part of a
T1 to be shared outside of this NFAS-trunk group. In other words, they do not
allow one of the T1 interfaces (of this NFAS group) to be fractionalized into two
or more uses. It must be dedicated to this given customer. Therefore, the
following usage rules apply:
• All members of an NFAS DS1 (that are administered) must belong to the same
trunk-group
• All members of this trunk-group must belong to a single signaling group
5. Enter show to check the signaling groups administration.
The report lists the signaling groups parameters. For example:
Sig-group Tg-Select Assoc-Sig Prime-Dchan Nfas-Modules/Nfas-Id
