Functional Description
IDT82P2288
In CRC to Non-CRC inter-working.
It is out of Basic frame synchronization.
It is out of CRC multi-frame synchronization.
It is out of CAS Signaling multi-frame synchronization.
The new-found Basic frame alignment pattern position differs from the previous one.
FAS/NFAS Bit/Pattern Error occurs.
CRC Multi-Frame Alignment Pattern Error occurs.
CAS Signaling Multi-Frame Alignment Pattern Error occurs.
CRC-4 Error occurs.
Offline Basic frame search indication.
Far End Block Error occurs.
Continuous RAI & FEBE Error occurs.
Continuous FEBE Error occurs.
At the first bit of each CRC Multi-Frame.
At the first bit of each CRC Sub Multi-Frame.
At the first bit of each CAS Signaling Multi-Frame.
There is change in the corresponding SaX[1:4] bits. The ‘X’ is from 4 through 8.
Any 12 consecutive Sa6 bits or any 3 consecutive 4-bit Sa6 codewords are matched
with 0x888, 0xAAA, 0xCCC, 0xEEE or 0xFFF.
NT FEBE Error occurs.
NT CRC Error occurs.
2 out of 3 sliding Sa7 bits are received as logic 0.
