Bit Name
Default
Bit No.
Type
This bit determines the criteria of out of Basic frame synchronization.
= 0: 3 consecutive FAS pattern errors lead to out of Basic frame synchronization.
= 1: 3 consecutive FAS pattern errors or 3 consecutive NFAS errors lead to out of Basic frame synchronization.
= 0: Disable searching for the Channel Associated Signaling (CAS) Multi-Frame.
= 1: Enable searching for the Channel Associated Signaling (CAS) Multi-Frame after the Basic frame synchronization is acquired.
= 0: Disable searching for the CRC Multi-Frame.
= 1: Enable searching for the CRC Multi-Frame after the Basic frame synchronization is acquired.
These two bits determine the criteria of FAS/NFAS Bit/Pattern Error generation:
These two bits determine the criteria of out of CAS Signaling Multi-Frame synchronization:
= 0: Stop searching for CRC Multi-Frame alignment pattern in CRC to non-CRC interworking mode.
= 1: Enable searching for CRC Multi-Frame alignment pattern even if CRC to non-CRC interworking has been declared.
