Specifying the Idle Pattern

You can set a specific pattern to be transmitted between HDLC packets on all unconfigured timeslots
that belong to a channelized T3 interface. To do so, use the idle pattern command.
idle pattern patterns
[no] idle pattern patterns
Where patterns is a number in the range of 0x0 to 0xff (hexadecimal) or 0 to 255 (decimal). You can
enter this value in either hexadecimal or decimal form. Values of 0 to 254 set the idle pattern to HDLC
flags (0x7e); a value of 255 sets the pattern to 0xff (all ones).
Note Some systems interpret marks, 0xff, as an abort signal. Therefore, flags, 0x7e, is preferred.
The default idle pattern is 0x7e.
