Configuring Fractional T1 Time Slots
By default, all the time slots on a T1 interface are used. To configure the number of time slots allocated to a fractional T1 interface, include the timeslots statement at the [edit interfaces interface-name t1-options] hierarchy level:
For T1 interfaces, the time-slot range is from 1 through 24. There are 24 time slots on a T1 interface. You can designate any combination of time slots. To configure ranges, use hyphens. To configure discontinuous time slots, use commas. Do not include spaces.
Example: Configuring Fractional T1 Time Slots
Use Time Slots 1 Through 10
Use Time Slots 1 Through 5, 10, and 24
Use the First Four Odd-Numbered Time Slots
