Configuring DS0 Trunk Group Dial Out
The DS0 Trunk Group Dial Out feature adds functionality that enhances outbound call routing by giving
the user control over individual DS0s for outbound calls. Previous to this feature, outbound DS0s could
not be configured separately from DS1s. The dial out capabilities of a DS1 applied to all DS0s under
that DS1.
Currently, the aggregation of DS1s into trunk groups is done via the Trunk Group Resource Manager
(TGRM). The DS0 Trunk Group Dial Out feature enables the TGRM subsystem to aggregate DS0s into
trunk groups also. The dial out capabilities of these DS0 trunk groups can then be configured directly at
the DS0 level, via the TGRM CLI and by setting the Authentication Authorization and Accounting
(AAA) attributes.
The configuration of DS0s for outbound calls enables the Dial on Demand feature to initiate outbound
calls over a set of B channels.
DS0 Dial Out Trunk Groups are configured on a Network Access Server (NAS). They support both
digital and asynchronous calls and can be configured for the following types of circuits.
•
A trunk group is a logical grouping of multiple T1/E1 interfaces with the same signaling characteristics.
A single trunk group can contain up to 64 trunks. Each trunk group can consist of DS0s from different
circuits, but each individual DS0 can belong to only one trunk group. Trunk groups configured for ISDN
can consist of both PRI and NFAS interfaces.
Note
DS0 Dial Out Trunk Groups can be provisioned for dial out only at present and should not be provisioned
as targets of dial-peers.
Note
DS0 Dial Out Trunk Groups do not support for voice interfaces.
Trunk Group Resource Manager
The Trunk Group Resource Manager (TGRM) supports the logical grouping, configuration, and joint
management of one or more interfaces. The TGRM is used to store configuration information and to
accept or select an interface from a trunk group when requested.

Make sure the cable connection is not loose or disconnected if the Layer 1 Status is "Deactivated."
This status message indicates a problem at the physical layer.
There may be a problem with your telco or the framing and line code types you entered may not
match your telco's. A Layer 2 error indicates that the gateway cannot communicate with the telco.
There is a problem at the data link layer.
