. The total number of Loss of Signal ( ) events that have been detected
LOS
on this port. An event occurs after 175 contiguous pulse positions with no pulses (10
LOS
absent pulses on ports). An failure is cleared after the switch observes a single pulse.
E1 LOS
. The occurrence of either a bipolar violation or an excessive zeros
error. A bipolar violation is the occurrence of a pulse of the same polarity as the previous
pulse. In coded signals, a bipolar violation is a pulse of the same polarity as the previ-
B8ZS
ous without being part of the zero substitution code. An excessive zeros error is the occur-
rence of more than 15 contiguous zeros in an -coded signal; in a -coded signal, it is
AMI B8ZS
the occurrence of seven (7) or more contiguous zeros.
