Command Reference Guide T1 Interface Configuration Command Set

tdm-group <group number> timeslots <1-24> speed [56 | 64]

Use the tdm-group command to create a group of contiguous DS0s on this interface to be used during the

cross-connect process. See cross-connect <#> <from interface> <slot/port> <tdm-group#> <to

interface> <slot/port> on page 147 for related information.

Changing tdm-group settings could potentially result in service interruption.

Syntax Description

Numerical label to identify the created tdm-group (valid range: 1-255).

timeslots

Keyword to specify the DS0s to be used in this tdm-group.

<1-24>

Specifies the DS0s to be used in the tdm-group. This can be entered as a single

number representing one of the 24 T1 channel timeslots or as a contiguous group

of DS0s. (For example, 1-10 specifies the first 10 channels of the T1.)

speed

*Optional

Keyword to specify the individual DS0 rate on the T1 interface. If the

speed

keyword is not used, the ADTRAN OS assumes a DS0 rate of 64 kbps.

Specifies a DS0 rate of 56 kbps.

Specifies a DS0 rate of 64 kbps.

Default Values

By default, there are no configured tdm-groups.

Command Modes

(config-t1 1/1)# T1 Interface Configuration Mode required (does not apply to DSX-1 interfaces)

Command History

Release 1.1 Command was introduced

Usage Examples

The following example creates a tdm-group (labeled

) of 10 DS0s at 64 kbps each:

(config)#

interface t1 1/1

(config-t1 1/1)#

tdm-group 5 timeslots 1-10 speed 64
