How to Configure Layer 1 Features

Cisco IOS Release 12.0(27)S1

• To set the first T1 line into remote payload fdl ansi bit loopback, use the loopback remote payload

fdl ansi path configuration command.

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# controller sonet 6/0

Router(config-controller)# sts-1 1

Router(config-ctrlr-sts1)# vtg 4 t1 1 loopback remote payload fdl ansi

Router(config-ctrlr-sts1)#

Enabling Remote Performance Reports

To enable and disable 1-second transmissions of performance reports through the Facility Data Link

(FDL), use the t1 t1-line-number fdl ansi configuration command, using the extended command prefix

that is appropriate to your channelized configuration. The command must be used on both ends of the

connection. In this command, t1-line-number is a number in the range from 1 to 4 in vt-15 mode, and 1

to 28 in ct3 mode.

The following example shows how to enable performance reports for a T1 line in vt-15 mode:

Router(config)# controller sonet 6/0

Router(config-controller)# sts-1 1

Router(config-ctrlr-sts1)# vtg 4 t1 1 fdl ansi

Router(config-ctrlr-sts1)#

Note You can use this command only when the T1 framing is ESF. Use the no form of the

command to disable remote performance reports. The 1-Port CHOC-12 ISE line card

supports the reporting of controlled slip seconds (CSS). Controlled slip seconds are

reported from the far end only when a network payload loopback is set.

Note If you do not first enable remote performance data with the t1 t1-line-number fdl ansi

command, the following message is displayed:

T1 1 - Remote Performance Data (Not available)

Configuring a BER Test on a T1 Line
