The default selection for T1 is 110 feet.
The cable length is given in decibels (long-haul) or feet (short-haul). A short-haul cable length is less than 660 feet, while a long-haul is greater than 660 feet. For a long-haul cable, the line built-out is the receiver gain in decibels.
This option is applicable only for T1 ports:
