Configuring T1 Line Encoding

By default, T1 interfaces use B8ZS line encoding. You can configure AMI line encoding if necessary.

To have the interface use AMI line encoding, include the line-encoding statement at the [edit interfaces interface-name t1-options] hierarchy level, specifying the ami option:

[edit interfaces interface-name t1-options]

line-encoding ami; 

To explicitly configure B8ZS line encoding, include the line-encoding statement at the [edit interfaces interface-name t1-options] hierarchy level, specifying the b8zs option:

[edit interfaces interface-name t1-options]

line-encoding b8zs;

When setting the line encoding parameter, you must set the same value for paired ports. Ports 0 and 1 must share the same value, and likewise ports 2 and 3 must share the same value, but ports 0 and 1 can have a different value from that of ports 2 and 3.
