Purpose
Enters global configuration mode.
Specifies the E3 controller name in the notation
rack/slot/module/port and enters E3 configuration mode.
(Optional) Sets the clocking for individual E3 links.
Note
The default clock source is internal.
When configuring clocking on a serial link, you
Note
must configure one end to be internal, and the other
end to be line. If you configure internal clocking on
both ends of a connection, framing slips occur. If
you configure line clocking on both ends of a
connection, the line does not come up.
(Optional) Specifies the distance of the cable from the
router to the network equipment.
The default cable length is 224 feet.
