Configuring T1 and E1 Lines
You can configure T1 and E1 interfaces on paths and tributaries. To do so, complete the
following steps:
Configure the clock source. You must coordinate this setting with the other end of
1.
the line to establish which end is the transmit (internal) clock and which is the receive
(line) clock.
(Optional) Configure the framing format.
2.
(Optional) Enable processing of SNMP link status information about an interface
3.
and its associated tributary.

4.
(Optional) Enable processing of SNMP link status information about a channel group.
5.
(Optional—T1 only) Configure FDL messages.
6.
(Optional) Assign a text description or an alias to the interface.
7.
Use to assign a text description or an alias to a DS1 (T1) or an E1 channel group for
channelized SONET and SDH interfaces.
You can use this command to help you identify the interface and keep track of interface
connections.
The description or alias can be a maximum of 80 characters.
Use "show controllers sonet ds1|e1" on page 153 to display the text description.
Example
host1(config-controller)#path 10 e1 1/5/1 channel-group 4
description westford e1 151.4
Use the no version to remove the text description or alias.
See path ds1|e1 channel-group description.

Example
host1 (config-controll)#path 12 e1 1/4/1 channel-group 2 shutdown
Use the no version to restart a disabled channel group.
See path ds1|e1 channel-group shutdown.
