The bipolar line output signal from TRING_n is connected to this pin via a 270
resistor to check for line driver failure.
NOTE: This pin is internally pulled "Low".

If MTIP_n and MRING_n has no transition pulse for 128 ± 32 TxCLK_n cycles,
DMO_n goes “High” to indicate the driver failure. DMO_n output stays “High”
until the next AMI signal is detected.

This output pin toggles "High" if the receiver has detected a Loss of Signal Con-
dition.
The criteria for declaring /clearing an LOS Condition depends upon whether it is
operating in the E3 or STS-1/DS3 Mode.

This output pin toggles "High" if a Loss of Lock Condition is detected. LOL
(Loss of Lock) condition occurs if the recovered clock frequency deviates from
the Reference Clock frequency (available at either E3CLK or DS3CLK or STS-
1CLK input pins) by more than 0.5%.
