21 28-Channel Framer Block Functional Description
21.19 Performance Monitoring Functional Integration into Superframer
The framer monitors the recovered line data for alarm conditions and errored events, and then presents this infor-
mation to the system through the microprocessor registers. To a lesser degree of importance, the framer also mon-
itors the receive system data when in the switching mode and presents the information to the system through the
microprocessor registers.
In the transport mode, both directions are monitored for alarm conditions and error events.
