Configuring Fractional E1 IQ Interfaces

By default, all the time slots on a channelized E1 interface are used. To configure a fractional E1 interface on a Channelized E1 IQ PIC, you must perform the following tasks:

Include the no-partition statement at the [edit interfaces ce1-fpc/pic/port] hierarchy level:[edit interfaces ce1-fpc/pic/port] no-partition interface-type e1;
This configuration creates interface e1-fpc/pic/port.
Configure the number of time slots allocated to the E1 IQ interface by including the timeslots statement at the [edit interfaces e1-fpc/pic/port e1-options] hierarchy level: [edit interfaces e1-fpc/pic/port e1-options] timeslots time-slot-range;

NxDS0 time slots configured on either a channelized STM1 IQ interface or a channelized E1IQ interface are numbered from 1 to 31 (0 is reserved), while fractional E1 time slots are numbered from 2 to 31 (1 is reserved).

To configure ranges, use hyphens. To configure discontinuous time slots, use commas. Do not include spaces.

For more information about E1 time slots, see Configuring Fractional E1 Time Slots.

Example: Configuring Fractional E1 IQ Interfaces

Configure a fractional E1 interface that uses time slots 2 through 10:



[edit interfaces ce1-0/0/0]

no-partition interface-type e1;
[edit interfaces e1-0/0/0 e1-options]
timeslots 2-10;

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