View CT3 interface view
Parameter feet: Cable length in the range 0 to 450 feet (0 to 137.2 meters).
Description Use the
cable command to configure the cable length on the CT3 interface.
Use the undo cable command to restore the default, that is, 49 feet (14.9
meters).
The cable length in this command refers to the distance between the router and
the cable distribution rack.
Example # Set the cable length to 50 feet (15.2 meters) on interface T3 2/0.

clock (CT3 interface view)
Syntax clock { master | slave }
undo clock
View CT3 interface view
Parameter master: Adopts the internal clock as the clock source.
slave: Adopts the line clock as the clock source.
Description Use the
clock command to configure clock source for the CT3 interface.
Use the undo clock command to restore the default, that is, line clock.
The clock source is selected depending on the connected remote device. If
connected to a transmission device, the local end uses the line clock. If connected
to a CT3 interface on another router, the local end can use whichever clock so
long as it is different from the one adopted at the remote end.
