Programming Information

Bit Name
= 0: The received bit is not the first bit of each SF/ESF/T1 DM/SLC-96 frame.
= 1: The first bit of each SF/ESF/T1 DM/SLC-96 frame is received.
This bit will be cleared if a ’1’ is written to it. This bit can not be updated during out of synchronization state.
In SF format, each received Ft bit is compared with the expected one (refer to Table 12). Each unmatched Ft bit leads to an Ft bit error event.
= 0: No Severely Ft Bit Error event is detected.
= 1: The Severely Ft Bit Error event is detected.
In ESF format, when 2 or more frame alignment bit errors are detected in a 1-ESF-frame fixed window, the severely frame alignment bit error
= 0: No Severely Frame Alignment Bit Error event is detected.
= 1: The Severely Frame Alignment Bit Error event is detected.
In T1 DM format, each received Ft bit is compared with the expected one (refer to Table 14). Each unmatched Ft bit leads to an Ft bit error event.
= 0: No Severely Ft Bit Error event is detected.
= 1: The Severely Ft Bit Error event is detected.
This bit will be cleared if a ’1’ is written to it.
In ESF format, when the local calculated CRC-6 of the current received ESF frame does not match the received CRC-6 of the next received ESF
= 0: No CRC-6 Error event is detected.
= 1: The CRC-6 Error event is detected.
This bit will be cleared if a ’1’ is written to it.
In SF format, each received F bit is compared with the expected one (refer to Table 12). Each unmatched F bit leads to an F bit error event.
= 0: No F Bit Error event is detected.
= 1: The F Bit Error event is detected.
In ESF format, each received Frame Alignment bit is compared with the expected one (refer to Table 13). Each unmatched bit leads to a frame
= 0: No Frame Alignment Bit Error event is detected.
= 1: The Frame Alignment Bit Error event is detected.
In T1 DM format, each received F bit is compared with the expected one (refer to Table 14). Each unmatched F bit leads to an F bit error event
= 0: No F Bit Error event is detected.
= 1: The F Bit Error event is detected.
