Description This command configures the line-length parameter of the BITS output. This is the distance
in feet between the network element and the office clock (BITS/SSU).
This command is only applicable when the BITS interface-type is DS1.
Note: On the 7210 SAS-T and 7210 SAS-Mxp, BITS2 inherits the values configured for
BITS1.
Default 110
Parameters 110 — Specifies that the distance is from 0 to 110 feet.
220 — Specifies that the distance is from 110 to 220 feet.
330 — Specifies that the distance is from 220 to 330 feet.
440 — Specifies that the distance is from 330 to 440 feet.
550 — Specifies that the distance is from 440 to 550 feet.
660 — Specifies that the distance is from 550 to 660 feet.
