Monitor Ring Input - Channel 5:
The bipolar line output signal from TRING_n is connected to this pin via a 270 Ω
resistor to check for line driver failure.
NOTE: This pin is internally pulled up.

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.
