Configuring an Unframed E1 Line
Use the following command to configure an unframed E1 line.
path e1 unframed
■
Use to configure an unframed E1 on the path.
■
You cannot configure a mixture of T1 and E1 lines on the same cOCx/STMx line
module.
■
When you issue this command, the router creates one channel for the unframed
E1 line, and assigns the number one to that channel.
■
Example
host1(config-controller)# path 1 e1 1/7/4
host1(config-controller)# path 1 e1 1/7/4 unframed
■
Use the no version to delete an unframed E1 interface from the path.
■
See path e1 unframed.
Configuring T1 and E1 Lines
You can configure T1 and E1 interfaces on paths and tributaries. To do so, complete
the following steps:
1.
Configure the clock source. You must coordinate this setting with the other end
of the line to establish which end is the transmit (internal) clock and which is
the receive (line) clock.
2.
(Optional) Configure the framing format.
3.
(Optional) Enable processing of SNMP link status information about an interface
and its associated tributary.
4.
Configure the T1 or E1 line parameters.
5.
(Optional) Enable processing of SNMP link status information about a channel
group.
6.
(Optional—T1 only) Configure FDL messages.
7.
(Optional) Assign a text description or an alias to the interface.
path ds1|e1 channel-group description
■
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.
