IMPORTANT If problems persist after you have followed the Recommended Actions contact ADTRAN Technical Support at 888 423 8726 AIS LED is Blinking Alarm Indication Signal or Blue Alarm A Blue Alarm also called AIS keep alive and all ones when indicated at TRACER 4103 4203 is generated by the attached equipment The root cause must be determined at the attached equipment A typical cause of a blue alarm is a lack of input to a CSU Recommended Action 1 Verify the input to any attached data equipment BPV LED is Lit Bipolar Violations This alarm will activate when the incoming T1 stream presents Bipolar Violations BPV BPVs indi cate an improper configuration or a faulty cable plant Recommended Actions 1 Verify the TRACER 4103 4203 unit and the attached equipment are configured for the same line coding AMI or B8ZS Verify that the Line Buildout LBO of the attached equipment is correct Inspect the cable plant for split pairs A split pair is a condition in which the T1 interface is incorrectly wired into the cable plant Each interface direction transmit and receive is carried on two signals tip and ring Normally tip and ring for the transmit signal comprise the two wires for a single twisted pair in the bundle It is not uncommon for one connection from the transmit interface and one connection from the receive interface to comprise another twisted pair This condition is referred to as a split
3. IMPORTANT The voltage level present at the RSSI test point represents only a relative signal level of receive strength from the far end No direct correlation can be made between RSSI voltage level and actual receive level in dBm This test point is provided to assess relative signal level for alignment of antennas RF LOW The RF LO LED indicates that the received signal is within 10dB of the minimum received signal strength approximately 80 dBm If this indicator is on the link performance may be marginal The antennas should be peaked in azimuth and elevation until the desired signal level is achieved RSSI may be monitored on the front of the TRACER 4103 4203 If the received signal is too strong and RSSI reaches a maximum such that the peak cannot be discerned then the transmitter power on the far end should be turned down At this point the radio link should be operational Proper operation can be determined by the status of the RF DOWN LED If this LED is on the link is not operational If this LED is not on the link is operating Certain types of interference can cause one end of a path to operate and the other end to fail In some instances this may be corrected by swapping the frequency plan at each end thus avoiding the interference if it is stronger at one end than the other Changing the spreading code at each end may also allow interference to be mitigated ALARM CONTACTS Normally open and normally closed alar
