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:
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
rx FEBE since last clear counter 0, since reset 22
Data in current interval (446 seconds elapsed):
0 Line Code Violations, 0 P-bit Coding Violation

0 P-bit Err Secs, 0 P-bit Sev Err Secs
0 Sev Err Framing Secs, 0 Unavailable Secs
0 Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Sev Err Secs
Data in Interval 1:
0 Line Code Violations, 0 P-bit Coding Violation
0 C-bit Coding Violation
0 P-bit Err Secs, 0 P-bit Sev Err Secs
0 Sev Err Framing Secs, 0 Unavailable Secs
0 Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Sev Err Secs
Data in Interval 2:
0 Line Code Violations, 0 P-bit Coding Violation
0 C-bit Coding Violation
0 P-bit Err Secs, 0 P-bit Sev Err Secs
0 Sev Err Framing Secs, 0 Unavailable Secs
0 Line Errored Secs, 0 C-bit Errored Secs, 0 C-bit Sev Err Secs
Command Purpose
Router# configure terminal Enters global configuration mode.
Router(config)# interface serial slot/subslot/port Selects the interface to configure and enters
interface configuration mode.
• slot/subslot/port—Specifies the location of the
interface. See the
“Specifying the Interface
Address on a SPA” section on page 17-5.
Router(config-if)# cablelength length Sets the cable length.
• length—Range is 0 to 450 feet. The default is
10 feet.
