Description
Loop Mode 4. If driven high the loopback mode of channel 4 will be set to re-
mote loop. Otherwise theloopback mode will remain at local loop. The
actualloopback will be activated when the LOOPEN4 is asserted.
Loop Mode 3. If driven high the loopback mode of channel 3 will be set to re-
mote loop. Otherwise the loopback mode will remain at local loop. The
actual loopback will be activated when the LOOPEN3 is asserted.
Receiver 4 Input. Receiver 4 bipolar input connected to coupling capacitor or
pulse transformer.
Receiver 4 Loss of Signal. Asserted during LOS condition. Clear otherwise.
Receiver 3 Loss of Signal. Asserted during LOS condition. Clear otherwise.
Receiver 3 Input. Receiver 3 bipolar input connected to coupling capacitor or
pulse transformer.
