FERI:
FAS/NFAS Bit/Pattern Error event is generated. During out of Basic frame synchronization state, the FAS/NFAS Bit/Pattern Error detection is sus-
pended.
COFAI:
E1 TS0 International / National (054H, 154H, 254H, 354H)
Si0:
and is held during out of Basic frame state.
Si1:
and is held during out of Basic frame state.
A:
NFAS frame and is held during out of Basic frame state.
Sa[4:8]:
frame and are held during out of Basic frame state.
Programming Information
Bit Name
Default
Bit No.
Type
When Basic frame is synchronized and the criteria set by the WORDERR bit (b3, E1-04EH,...) and the CNTNFAS bit (b4, E1-04EH,...) are met, a
= 0: No FAS/NFAS Bit/Pattern Error event is detected.
= 1: The FAS/NFAS Bit/Pattern Error event is detected.
This bit will be cleared if a ’1’ is written to it.
= 0: The Basic frame alignment pattern position is not changed.
= 1: The new-found Basic frame alignment pattern position differs from the previous one.
This bit will be cleared if a ’1’ is written to it.
This bit reflects the content in the International bit of the latest received NFAS frame. It is updated on the boundary of the associated NFAS frame
This bit reflects the content in the International bit of the latest received FAS frame. It is updated on the boundary of the associated FAS frame
This bit reflects the content in the Remote Alarm Indication bit of the latest received NFAS frame. It is updated on the boundary of the associated
These bits reflect the content in the National bit of the latest received NFAS frame. They are updated on the boundary of the associated NFAS
