Channelization of OC12/STM4 IQE PIC (SDH Mode)

 

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

In Figure 1, a Channelized OC12/STM4 IQE 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 E3 interfaces.

  3. A channelized AU-4 interface partitioned into E1 interfaces.

  4. A channelized AU-4 interface partitioned into CE1 interfaces partitioned into NxDS0 interfaces.

  5. A channelized AU-4 interface partitioned into T1 interfaces.

  6. A channelized AU-4 interface partitioned into CT1 interfaces.

  7. A channelized AU-4 interface partitioned into T3 interfaces partitioned into T1 interfaces.

  8. A channelized AU-4 interface partitioned into CT3 interfaces partitioned into CT1 interfaces.

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