Configuring Fractional T1 IQ Interfaces

By default, all the time slots on a channelized T1 interface are used. To configure a fractional T1 interface on a Channelized OC12 IQ or IQE PIC, you must perform the following tasks:

Configure a T1 IQ interface. For more information, see Configuring T1 IQ Interfaces.
Configure the number of time slots allocated to the T1 IQ interface by including the timeslots statement at the [edit interfaces t1-fpc/pic/port<:channel> t1-options] hierarchy level: [edit interfaces t1-fpc/pic/port<:channel> t1-options] timeslots time-slot-range;

For channelized T1 IQ interfaces, the time-slot range is from 1 through 24. You can designate any combination of time slots. To configure ranges, use hyphens. To configure discontinuous time slots, use commas. Do not include spaces. For more information, see Configuring Fractional T1 Time Slots.

Example: Configuring Fractional T1 IQ Interfaces

Configure a fractional T1 interface that uses time slots 1 through 5 and 10:



[edit interfaces coc12-0/0/0]
partition 1 oc-slice 1 interface-type coc1;
[edit interfaces coc1-0/0/0:1]
partition 1 interface-type t1;
[edit interfaces t1-0/0/0:1:1 t1-options]
timeslots 1-5,10;

For a full configuration example, see the JUNOS Feature Guide.
