Channelization of OC12/STM4 IQ and Channelized OC12/STM4 IQE PICs (SONET Mode)

Channelized OC12/STM4 IQ PICs and Channelized OC12/STM4 IQE PICs can be configured to operate in SONET or SDH mode and partitioned into various partitions. Figure 1 illustrates one possible channelization configuration for Channelized OC12/STM4 IQ and IQE PICs operating in SONET mode.

In the example in Figure 1, a Channelized OC12/STM4 IQ or IQE PIC operating in SONET mode is partitioned into the following OC slices:

1. An OC3 interface.
2. Another OC3 interface.
3. A channelized OC1 partitioned into T1 interfaces.
4. A channelized OC1 converted into a T3 interface.
5. A channelized OC1 partitioned into T1 interfaces and channelized T1s, which are partitioned into NxDS0 interfaces.
6. A channelized OC1 converted into a channelized T3, which is partitioned into T1 interfaces.
7. A channelized OC1 converted into a channelized T3, which is partitioned into T1 interfaces and a channelized T1, which is partitioned into NxDS0 interfaces.
8. A channelized OC1 partitioned into channelized T1s, which are partitioned into NxDS0 interfaces.
