Configuring Cable Length

The cablelength command compensates for the loss in decibels based on the distance from the device
to the first repeater in the circuit. A longer distance from the device to the repeater requires that the signal
strength on the circuit be boosted to compensate for loss over that distance. To configure cable length,
use the following commands:
Command
Router# configure terminal
Router(config)# interface serial slot/subslot/port Selects the interface to configure and enters
Router(config-if)# cablelength length
Verifying Cable Length Setting
Use the show interfaces serial command to verify the cable length setting:
Router# show interfaces serial 2/0/0
Serial2/0/0 -
Framing is c-bit, Clock Source is Internal
Bandwidth limit is 44210, DSU mode 0, Cable length is 200
