optical interface with NRZ coding, the decoder is by-passed and no code violations are
detected.
Additionally, the receive line interface contains the alarm detection for Alarm Indication
Signal AIS (Blue Alarm) and the Loss of Signal LOS (Red Alarm).
Pulse density violations are detected and indicated via bit FRS1.PDEN.
The signal at the ternary interface is received at both ends of a transformer.

There are different definitions for detecting Loss of Signal alarms (LOS) in the ITU-T
G.775 and AT&T TR 54016. The FALC
indication is performed by generating an interrupt (if not masked) and activating a status
bit. Additionally a LOS status change interrupt is programmable via register IPC.SCI.

: t
An alarm is generated if the incoming data stream has no pulses (no transitions) for a
certain number (N) of consecutive pulse periods. “No pulse” in the digital receive
interface means a logical zero on pins RDIP/RDIN/ROID. A pulse with an amplitude
less than Q dB below nominal is the criteria for “no pulse” in the analog receive
interface (LIM1.DRS=0). In short haul mode (LIM0.EQON = 0), the receive signal level
Q is programmable via three control bits LIM1.RIL2...0 in a range of about 1400 to 200
mV differential voltage between pins RL1/2 (see
