Alarm Description Recommendation
LOS A Loss of Signal indicates that there is either no signal arriving from the
adjacent E1/T1 device or no valid E1 voltage mask or no voltage alteration
between positive and negative amplitudes.
For E1 links, the LOS counter will increase by one for each second during
which a consecutive 255 pulses have no pulse of negative or positive polarity.
For T1 links, the LOS counter will increase by one for each second during
which a consecutive 192 pulses have no pulse of negative or positive polarity.
A LOS alarm can also be noticeable when the SYNC LED is off (Green
indicates proper synchronization).
Check the physical layer
(connectors, cables, etc.)
