Monitor Ring Input:
This input pin along with the MTIP pin function as the input pins for the Transmit
Drive Monitor. These two input pins are used to determine whether or not a
bipolar line signal is being output via the TTIP and TRING output pins. The
Transmit Drive Monitor circuit will toggle the DMO output pin “high” denoting a
Transmit Line Fault condition if no bipolar pulses are detected via the TTIP/
TRING output pins for 128 bit-periods.
Connect this input pin to the TRING output pin via a 270 ohm resistor.
N
OTE
:
Tie this input pin to GND if you do not intend to use the Transmit Drive
Monitor.
