T3/E3 and T1/E1 Controller Commands on Cisco IOS XR Software

---

This module describes the commands to configure T3/E3 and T1/E1 controllers on routers supporting Cisco IOS XR software.

bert e1

To start or stop a configured bit error rate test (BERT) on an E1 controller or channel group, use the bert e1 command in EXEC mode. To return to the default state, use the no form of this command.

bert e1 instance [channel-group channel-group-number] {start | stop}

no bert e1 instance [channel-group channel-group-number] {start | stop}

Syntax Description

channel-group channel-group-number	(Optional) Channel group number. When an E1 data line is configured, channel group numbers can be values from 0 to 30. Note For any of the DS0 time slots within the time slot range provided for the channel group, use time slot -1 as the channel number.
start	Starts the BERT on the E1 controller or channel.
stop	Stops the BERT on the E1 controller or channel.

Defaults

No default behavior or values

Command Modes

EXEC

Command History

Release	Modification
Release 3.3.0	This command was introduced on the Cisco XR 12000 Series Router.
Release 3.4.0	No modification.
Release 3.5.0	No modification.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

You need to use the bert pattern command in E1 configuration mode or channel configuration mode to configure a BERT pattern before you can start a BERT on an E1 controller or channel group.

To view the BERT results, use the show controllers e1 command in EXEC mode. The BERT results include the following information:

•Type of test pattern selected

•Status of the test

•Interval selected

•Time remaining on the BERT

•Total bit errors

•Total bits received

BERT is data intrusive. Regular data cannot flow on a line while the test is in progress. The line is put in an alarm state when a BERT is in progress and restored to a normal state after a BERT has been terminated.

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

You can specify a cable length from 0 to 450 feet; however, the hardware recognizes only two ranges: 0 to 49 and 50 to 450. For example, entering 35 feet uses the 0 to 49 range. If you later change the cable length to 40 feet, there is no change because 40 is still within the 0 to 49 range. However, if you change the cable length to 50, the 50 to 450 range is used. The actual number you enter is stored in the configuration file.

Channel group number. When a T1 controller is configured, channel group numbers can be values from 0 to 23. When an E1 controller is configured, channel group numbers can be values from 0 to 30. Note For any of the DS0 time slots within the time slot range provided for the channel group, use time slot -1 as the channel number.

Defaults

The channel-group command is available only on channelized SPAs.

Use the channel-group command in configurations in which the router must communicate with a T1 or an E1 fractional data line. The channel group number may be arbitrarily assigned and must be unique for the controller. An associated serial interface is created with each defined channel group.

Before the channel group configuration is valid, you must define the associated DS0 time slots using the timeslots command.

To set clocking for individual T1 or E1 links, use the clock source command in T1 or E1 configuration mode. To return to the default, use the no form of this command.

clock source {internal | line}

no clock source

Syntax Description

internal	Specifies that the clock is generated from the internal clock of the T1 or E1 controller. Note When configuring clocking on a serial link, you need to configure one end to be internal and the other end to be line. If you configure internal clocking on both ends of a connection, framing slips occur. If you configure line clocking on both ends of a connection, the line does not come up.
line	Specifies that the clock on this controller derives its clocking from the external source to which the controller is connected, which is generally the telephone company central office (CO).

Defaults

The default clock source is internal.
