Frame (OOF), Loss Of Frame (LOF),
Far-End Receive Failure (FERF), line
Alarm Indication Signal (AIS), and
protection switching byte failure
alarms.
Inserts and extracts a 64- or 16-byte
section trace (C1) message using an
internal register bank. Detects an
unstable section trace message or
mismatch with an expected message,
and inserts Line AIS upon either of
these conditions.
Inserts FERF and AIS in the transmit
stream.
Provides LOS insertion, framing
pattern error insertion, and coding
violation insertion (B1 and B2) for
diagnostic purposes. B1 and B2 errors
can also be generated 鈥渙n-the-fly鈥?/div>
using an error insertion mask.
Provides a transmit and receive ring
control port, allowing alarm and
maintenance signal control and status
to be passed between mate STXCs for
ring-based add/drop multiplexer
applications.
