TRACER 6000 Series Integrated System Manual Section 5 User Interface Guide612806420L1-1F Copyright © 2005 ADTRAN, Inc. 71> E1 X STATUS/CONFIGURATION/LOOPBACK > E1X INTERFACE A LARMSDisplays any active alarms on the E1 link (reported from both the local and remote TRACER 64x0 units).These alarms include AIS, CRC, LCV, LOS, OOF, and RMT. Table 1 briefly describes these alarms. SeeSection 8, Troubleshooting Guide, on page 125 for more information on these alarms.> E1 X STATUS/CONFIGURATION/LOOPBACK > INTERFACE TYPE(Read Only) Displays the current interface type of the E1 module as either 75 OHM or 120 OHM.> E1 X STATUS/CONFIGURATION/LOOPBACK > ALARM REPORTINGDetermines 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, the CRAFT port, alarm contacts, menu screens, or LEDs on the front panel. By default, alarmreporting is set to E NABLED.> E1 X STATUS/CONFIGURATION/LOOPBACK > CRC4 DETECTIONWhen E NABLED, the receiver detects the CRC-4 checksum bits in the outgoing E1 data stream and checksthe received signal for errors.> E1 X STATUS/CONFIGURATION/LOOPBACK > SIGNALINGConfigures the framing format for the E1 link. The TRACER 64x0 transports E1 data across the link (aslong as the E1 signal is properly timed). Configure the framing format (using the S IGNALING menu) toenable the TRACER 64x0 to monitor incoming framing error events and indicate problems with theattached metallic service. The TRACER 64x0 supports MULTIFRAMED (also known as CAS), U NFRAMED (alldata stream with no framing sequence bits), and FRAMED (also known as CCS). The default value isF RAMED.Table 1. E1 Interface AlarmsAIS (Alarm Indication Signal) Activates when an incoming remote alarm is received from aconnected E1 device. An AIS signal is an unframed all one signal that replaces the normaltraffic signal.CRC (Loss of CRC-4 Framing) The receiver is unable to synchronize to the CRC-4 framepattern of the received signal.LCV (Line Code Violations) Activates when the incoming E1 stream presents line codingviolations.LOS (Loss of Signal) Activates when no E1 signal is present from the connected E1 equipment.LOS is activated after receiving 192 consecutive zeros.OOF (Out of Frame) The receiver is unable to synchronize to the FAS framing pattern of thereceived signal.RMT (Received Remote Alarm) Activates when an incoming remote alarm is received from theE1 device, indicating that a failure has occurred in the received direction.
