Channelization of OC12/STM4 IQ PIC (SDH Mode)

 

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

In Figure 1, a Channelized OC12/STM4 IQ PIC operating in SDH mode results in a channelized STM4 interface, which can be nonpartitioned into one SDH VC-4-VC interface or partitioned into the following OC slices:

  1. An SDH VC-4 interface.

  2. A channelized AU-4 partitioned into channelized T3 interfaces and T3 interfaces.

  3. Another channelized AU-4 interface converted into T3 interfaces.

  4. Another channelized AU-4 interface converted into a channelized T3 interface, which is partitioned further into a channelized T1 and a T1 interface. The channelized T1 interface is further partitioned into NxDS0 interfaces.

This is one of thousands of ways to configure a Channelized OC12/STM4 IQ PIC.
