TRACER 6000 Series Integrated System Manual Section 5 User Interface Guide612806420L1-1F Copyright © 2005 ADTRAN, Inc. 75>T1X STATUS/CONFIGURATION/LOOPBACK > T1X INTERFACE A LARMSDisplays any active alarms on the T1 link (reported from both the local and remote TRACER 64x0 units).These alarms include Red, Blue/AIS, Yellow, LOS, and bipolar violations (BPV). Table 2 briefly describesthese alarms. See Section 8, Troubleshooting Guide, on page 125 for more information on these alarms.> T1X STATUS /CONFIGURATION /LOOPBACK > ALARM R EPORTINGDetermines whether the TRACER 64x0 unit will report active alarms. If set to D ISABLED, no alarms will bedisplayed on this menu page. The A LARM R EPORTING parameter is independently configured for the localand remote TRACER 64x0 units. When set to D ISABLED, the TRACER 64x0 does not report active alarmsvia SNMP or the CRAFT port, and the status LEDs are off. By default, alarm reporting is set to E NABLED.>T1X STATUS/CONFIGURATION/LOOPBACK > T1X LINE BUILD OUTConfigures the T1 for the appropriate line build out, based on the distance to the T1 equipment. By default,the line build out for the TRACER 64x0 is 0 dB/133 FT.> T1X STATUS /CONFIGURATION /LOOPBACK > SIGNALINGConfigures the framing format for the T1 link for both the local and remote TRACER 64x0 units. TheTRACER 64x0 transports T1 data across the link (as long as the T1 signal is properly timed). Configurethe framing format (using the S IGNALING menu) to enable the TRACER 64x0 to monitor incoming framingerror events and indicate problems with the attached metallic service. The TRACER 64x0 supports bothextended superframe (ESF) and superframe (D4) framing formats. By default, the signaling method is setto ESF.> T1X STATUS /CONFIGURATION /LOOPBACK > LINE CODESets the line coding for the T1 link. The TRACER 64x0 supports bipolar eight-zero substitution (B8ZS)and alternate mark inversion (AMI) line coding. By default, the line code is set to B8ZS.> T1X STATUS /CONFIGURATION /LOOPBACK > LOOP/NORMAL STATEControls the loop status of the T1 link. Activates/deactivates loopback conditions for testing purposes.Table 2. T1 Interface AlarmsRED Activates when no T1 signal is present from the connected T1 equipment. LOS isactivated after receiving 192 consecutive zeros.BLUE/AIS (Alarm Indication Signal) Activates when an incoming remote alarm is received from aconnected T1 device. An AIS signal is an unframed all one signal that replaces the normaltraffic signal.YEL (Yellow Alarm) Activates when an incoming remote alarm is received from the T1 deviceindicating that a failure has occurred in the received direction.LOS (Loss of Sync) Occurs when the TRACER system cannot synchronize to the incoming T1data stream.BPV (Bipolar Violations) Activates when the incoming T1 stream presents BPVs. BPVs occurwhen two one bits are received back-to-back with the same polarity.
