Configure Single-Level Channels on a Channelized IQ Interface

You can subdivide a channelized interface directly into a set of large end channels. To configure part of a channelized IQ interface as a channel, include the partition statement at the [edit interfaces cxx-fpc/pic/port] hierarchy level. On a channelized OC-12 IQ interface, use the oc-slice option to create slice sizes corresponding to the desired bandwidth. On a channelized E1 IQ interface, use the timeslots option to define NxDS-0 channels or channel groups. On all channelized IQ interfaces, use the interface-type option to set the interface type (such as SONET OC-3 or T3). Once the channel interfaces are established, you can configure them the same way as regular interfaces.

One oc-slice in a channelized OC-12 IQ interface partition is equivalent to one OC-1/DS-3-sized channel. If you add three slices together in sequence as a triplet, these pieces become an OC-3-sized interface. However, you can configure triplets only with the following sequential slices: 1 - 3, 4 - 6, 7 - 9, 10 - 12.
