Table 1. DS3 Interface Alarms
BPV Activates when the incoming DS3 stream presents bipolar violations (BPVs). BPVs are
received when two consecutive “one” bits are the same polarity.
AIS An AIS signal is a properly aligned and framed alternating one-zero pattern. The TRACER
4205 will transmit a blue alarm (RMT) to the remote equipment when an incoming alarm is
received from a connected DS3 device. The remote equipment should transmit the AIS
yellow alarm which will be passed by the TRACER 4205 to the connected DS3 device.
RMT Activates when an incoming remote alarm is received (from the DS3 equipment) in the
DS3 EOC channel (bits X1 and X2 are both set to zero).
