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 41 on page 434 illustrates
one possible channelization configuration for Channelized OC12/STM4 IQ PICs
operating in SDH mode.
Figure 41: Sample Channelization of OC12/STM4 IQ PIC (SDH Mode)
In Figure 41 on page 434, 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:
a. An SDH VC-4 interface.
b. A channelized AU-4 partitioned into channelized T3 interfaces and T3 interfaces.
c.
d. Another channelized AU-4 interface converted into a channelized T3 interface,
This is one of thousands of ways to configure a Channelized OC12/STM4 IQ PIC.
Channelization of OC12 PIC (SONET Mode)
OC12 PICs can be configured to various smaller partitions, such as T3s.

Channelization of OC12/STM4 IQ PIC (SDH Mode)
Another channelized AU-4 interface converted into T3 interfaces.
which is partitioned further into a channelized T1 and a T1 interface. The
channelized T1 interface is further partitioned into NxDS0 interfaces.
