Configuring the CDS3 Frame Relay Port Adapter Interface

To manually change any of your default configuration values, perform the following steps, beginning in
global configuration mode:
Command
Step 1 Switch(config)# controller t3 card/subcard/port
Switch(config-controller)#
Step 2
Switch(config-controller)# clock source
{free-running | loop-timed | network-derived |
reference}
Step 3 Switch(config-controller)# framing {c-bit | m23} Configures the CDS3 Frame Relay port adapter
Step 4
Switch(config-controller)# cablelength
cablelength
Step 5
Switch(config-controller)# mdl {transmit {path |
idle-signal | test-signal} | string {eic | lic | fic |
unit | pfi | port | generator string}

Example
The following example shows how to change the cable length configuration to 300 using the cablelength
command.
Switch(config)# controller t3 3/0/0
Switch(config-controller)# cablelength 300
When using the cable length option, note that user-specified T3 cable lengths are structured into ranges
as follows: 0 to 224 and 225 to 450. If you enter a cable length value that falls into one of these ranges,
the range for that value is used.
For example, if you enter 150 feet, the 0 to 224 range is used. If you later change the cable length
to 200 feet, there is no change because 200 is within the 0 to 224 range. However, if you change the
cable length to 250, the 225 to 450 range is used. The actual number you enter is stored in the
configuration file.
