Configuring OC3 IQ Interfaces

To configure an OC3 IQ interface, include the partition, oc-slice, and interface-type statements at the [edit interfaces coc12-fpc/pic/port] hierarchy level, specifying the so interface type:

The partition number is the sublevel interface partition index. For SONET/SDH interfaces, the partition number does not correlate with bandwidth size. For OC3 interfaces, the partition number can be 1 through 4.

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. OC3 IQ interfaces must occupy three consecutive OC slices per interface, in one of the following forms:

• 1–3
• 4–6
• 7–9
• 10–12

By contrast, the T3 and OC1 IQ interfaces each occupy one OC slice per interface.

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

Example: Configuring OC3 IQ Interfaces

Configure an OC3 interface, using partition 1 and OC slices 4 through 6. This configuration creates interface so-1/1/0:1.
