loss-of-signal detector has a longer time constant than the digital LOS. Hence when the incoming signal
is lost, the digital LOS will activate first followed by the analog loss-of-signal detector. When a signal is
restored, the digital LOS will not be allowed to qualify a signal for no Excessive Zero violations until the
analog loss-of-signal detector has seen the signal rise above –18 dB. Governing specifications for the
loss-of-signal detectors are ANSI T1.231 and ITU G.775.
The recovered data from the receiver can be output in either bipolar format or Non Return to Zero (NRZ)
format. To select the bipolar format, the ZCSE* input is tied high. In this format, the B3ZS/HDB3
decoder is disabled and the received data is buffered and then output on the RPOS and RNEG outputs.
To select the NRZ format, the ZCSE* input is tied low. In this format, the B3ZS/HBD3 decoder is
enabled and the recovered data is B3ZS/HDB3 decoded and then logically OR’ed together and output at
the RNRZ output while the the RLCV output indicates line code violations.
