Command Reference Guide
short length: Matches transmission line shorter than 655 feet. The argument
length can take 133ft, 266ft, 399ft, 533ft, and 655ft, depending on the length of
transmission line.
Description
Using the ft1 cable command, you can configure attenuation or length of the
transmission line matched a T1-F interface. Using the undo ft1cable command,
you can restore the default setting.
By default, the transmission line attenuation matched T1-F interfaces is long
0db.
This command is mainly used for configuring the signal waveform required for
different types of transmission. In practice, you can decide whether to use this
command according to the signal quality at the receiving end. If the signal
quality is acceptable, the default setting can be used.
Example
Set the length of the transmission line matched the T1-F interface to 133 feet.
