Configuring Multilevel Channels on a Channelized IQ Interface
You can subdivide a channelized interface and then split these subchannelized interfaces into end channels. Creating small end channels might require multiple levels of channelization.
To configure a subdivided channelized interface within a partition of a channelized IQ interface, include the partition statement at the [edit interfaces cxx-fpc/pic/port] hierarchy level. On a channelized OC12 IQ interface, use the oc-slice option to create slice sizes corresponding to the desired bandwidth. On all channelized IQ interfaces, use the interface-type option to set the channelized interface type (such as channelized OC1).
On a channelized OC12 IQ interface, you can convert a subdivided channelized OC1 interface into a T3 or channelized T3 interface. To configure, include the no-partition statement at the [edit interfaces coc1-fpc/pic/port:channel] hierarchy level and set the interface-type to ct3. A ct3-fpc/pic/port:channel interface is the result. Such a conversion is known as M13 with C-bit parity mapping. T1 and DS0 channels created directly from a coc-1 interface use VT mapping.
To further split your channelized interfaces into even smaller channelized interfaces, use the partition and interface-type statements at the [edit interfaces cxx-fpc/pic/port:channel] hierarchy level. You can create channelized OC1, channelized T3, and channelized T1 interfaces, depending on the PIC type.
Finally, you configure these “channels of channels” as end channels. To configure end channels on a segmented channelized IQ interface, include the partition statement at the [edit interfaces cxx-fpc/pic/port:channel] hierarchy level. The number of channels in the hierarchy depends on how finely you partition the channelized IQ interface. Use the timeslots option to select NxDS0 level channels and the interface-type option to set the interface type (such as T1 or NxDS0). Once the resulting channels have been established, you can configure them as regular interfaces.
