Functional Description
4.7.2.3
A-Bit Access
If the TE3-CHATT detects a remote alarm indication (bit 2 in TS0 not containing the FAS
word) in the received data stream a RAS interrupt will be generated. With the
deactivation of the remote alarm the remote alarm status interrupt with RAS=’0’ is
generated.
By setting TFMR.AXRA the TE3-CHATT automatically transmits the remote alarm
bit = ’1’ in the outgoing data stream if the receiver detects a loss of frame alignment
(FRS.LFA = ’1’). If the receiver is in synchronous state (FRS.LFA = ’0’) the remote alarm
bit will be reset in the outgoing data stream.
