Alarm Indicators
• Signal Loss - The test set encountered the absence of data on the E1 signal. A
frame pulse may or may not be present.
• Frame Loss - The test set encountered an unexpected frame pattern. The frame
pattern did not match the one selected in 'Setup.'
• AIS Alarm - The test set encountered an unframed all-ones signal.
• TS 16 AIS Alarm - The test set encountered all ones in every timeslot sixteen.
• FAS Distant Alarm - The test set detected a FAS alarm being sent from the far
end. This alarm indicator is also known as RAI (Remote Alarm Indication)
• MFAS Distant Alarm - The test set detected an MFAS alarm being sent from
the far end.
• Pattern Inv - The pattern of the signal applied to the test set is inverted.
Results Indicators
• (Code) BPV - A momentary indicator that responds when a bipolar violation
occurs on the incoming signal applied to the Receive jack. HDB3 codes are not
considered a BPV and will not activate this indicator when the test set is set to
AMI mode.
• FAS - A momentary indicator that responds to a disruption in the frame
alignment signal.
• MFAS - A momentary indicator that responds to a disruption in the multi-frame
alignment signal. This indicator is applicable in only PCM-30 framing modes.
• CRC-4 - A momentary indicator that responds to a disruption of the incoming
CRC. This indicator is applicable in only CRC-4 framing modes.
• E-Bit - A momentary indicator that responds to the E-bit.
• Pattern - A momentary indicator that responds to a disruption of the incoming
pattern.
• Frame Slip - A momentary indicator that responds when the test set
encountered a disruption of the incoming frame pattern.
