224CHAPTER 13: FUNDAMENTAL CT1/PRI INTERFACE CONFIGURATION COMMANDS

error-diffusion restraint restart-channel

Syntax

error-diffusion restraint restart-channel serial interface-number:set-number

View

System view

Parameter

serial interface-number:set-number: Specifies a channel formed on a CE1/PRI

 

interface. The interface-numberargument is a CE1/PRI interface number, and the

 

set-numberargument is a channel set number.

Description

Use the error-diffusion restraint restart-channel command to bring up a

 

channel previously shut down by the error packet diffusion restraint function.

n The support of this command varies with device model.

 

This command applies to CT1/PRI interfaces and CE1/PRI interfaces only.

Example

# Bring up channel Serial 2/0:0 (assuming that the channel is shut down by the

 

error packet diffusion restraint function).

<Sysname> system-view

[Sysname] error-diffusion restraint restart-channel serial 2/0:0

fdl

Syntax fdl { ansi att none }

undo fdl

View CT1/PRI interface view

Parameter ansi: Implements ANSI T1.403 FDL. att: Implements AT&T TR 54016 FDL. none: Disables facilities data link (FDL).

Description Use the fdl command to set the behavior of the CT1/PRI interface on the FDL in ESF framing.

Use the undo fdl command to restore the default.

By default, FDL is disabled (none).

FDL is an embedded 4 kbps overhead channel within the ESF format for transmitting performance statistics or loopback code.

Example # Implement AT&T TR 54016 FDL on interface T1 2/0.
