Configuring T3 IQ Interfaces

To configure a T3 interface on an OC12 PIC, include the partition, oc-slice, and interface-type statements at the [edit interfaces coc12-fpc/pic/port] hierarchy level, specifying the coc1 interface type:



[edit interfaces coc12-fpc/pic/port]

partition partition-number oc-slice oc-slice-range interface-type coc1;

This configuration creates interface coc1-fpc/pic/port:channel.

Then, include the no-partition interface-type statement at the [edit interfaces coc1-fpc/pic/port:channel] hierarchy level, specifying the t3 interface type:



[edit interfaces coc1-fpc/pic/port:channel]

no-partition interface-type t3;

This configuration creates interface t3-fpc/pic/port:channel.

The partition number is the sublevel interface partition index and is correlated with the channel number. For channelized OC1 interfaces, the partition number can be from 1 through 12.

Note: For channelized OC12 interfaces, channel numbering begins with 0 (:0). For channelized OC12 IQ interfaces, channel numbering begins with 1 (:1).

The OC-slice range is the range of SONET/SDH slices. For SONET/SDH interfaces, the OC-slice range specifies the bandwidth size required for the interface type you are configuring. For channelized OC1 interfaces, the OC slice can be from 1 through 12. You can configure only one OC slice per channelized OC1 interface.

The interface type is the channelized interface type or clear channel you are creating. For channelized OC12 interfaces, type can be so or coc1.

Example: Configuring T3 IQ Interfaces

Configure a T3 interface using partition 3 and OC slice 3. This configuration creates interface t3-1/1/0:3.



[edit interfaces coc12-1/1/0]
partition 3 oc-slice 3 interface-type coc1;
[edit interfaces coc1-1/1/0:3]
no-partition interface-type t3;

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