and transmission line. In these kind of applications both devices are working in parallel

for redundancy purpose (see Figure 44). While one of them is driving the line, the other

one must be switched into transmit line tristate mode. If both channels are configured

identically and supplied with the same system data and clocks, the transmit path can be

switched from one channel to the other without causing a synchronization loss at the

remote end.

Loss-of-Signal Detection (T1/J1)

There are different definitions for detecting Loss-Of-Signal alarms (LOS) in the ITU-T

G.775 and AT&T TR 54016. The FALC56 covers all these standards. The LOS indication

is performed by generating an interrupt (if not masked) and activating a status bit.

Additionally a LOS status change interrupt is programmable by register GCR.SCI.
