SROS Command Line Interface Reference Guide E1 Interface Configuration Command Set

tdm-group <group number> timeslots <1-31> speed [56 | 64]

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

bind process. See crypto map <mapname> on page 731 for related information.

Syntax Description

<group number> 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.

<1-31> Specifies the DS0s to be used in the tdm-group. This can be entered as a single

number representing one of the 31 E1 channel timeslots or as a contiguous group

of DS0s. (For example, 1-10 specifies the first 10 channels of the E1.)

speed Optional.

Keyword to specify the individual DS0 rate on the E1 interface. If the speed

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

56 Specifies a DS0 rate of 56 kbps.

64 Specifies a DS0 rate of 64 kbps.

Default Values

By default, there are no configured tdm-groups.

Command Modes

(config-e1 1/1)# E1 Interface Configuration Mode required (does not apply to G.703 interfaces)

Usage Examples

The following example creates a tdm-group (labeled 5) of 10 DS0s at 64 kbps each:

(config)#interface e1 1/1

(config-e1 1/1)#tdm-group 5 timeslots 1-10 speed 64

Caution

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