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:
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:
For M Series and T Series routers, you must set the line encoding parameter for paired ports to the same value. 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.
