<strong>Measurement</strong> Results<br />

<strong>Measurement</strong> Results<br />

Alarm Indicators<br />

• Signal Loss - The test set encountered the absence of data on the E1 signal. A<br />

frame pulse may or may not be present.<br />

• Frame Loss - The test set encountered an unexpected frame pattern. The frame<br />

pattern did not match the one selected in 'Setup.'<br />

• AIS Alarm - The test set encountered an unframed all-ones signal.<br />

• TS 16 AIS Alarm - The test set encountered all ones in every timeslot sixteen.<br />

• FAS Distant Alarm - The test set detected a FAS alarm being sent from the far<br />

end. This alarm indicator is also known as RAI (Remote Alarm Indication)<br />

• MFAS Distant Alarm - The test set detected an MFAS alarm being sent from<br />

the far end.<br />

• Pattern Inv - The pattern of the signal applied to the test set is inverted.<br />

Results Indicators<br />

E1 Analyzer<br />

• (Code) BPV - A momentary indicator that responds when a bipolar violation<br />

occurs on the incoming signal applied to the Receive jack. HDB3 codes are not<br />

considered a BPV and will not activate this indicator when the test set is set to<br />

AMI mode.<br />

• FAS - A momentary indicator that responds to a disruption in the frame<br />

alignment signal.<br />

• MFAS - A momentary indicator that responds to a disruption in the multi-frame<br />

alignment signal. This indicator is applicable in only PCM-30 framing modes.<br />

• CRC-4 - A momentary indicator that responds to a disruption of the incoming<br />

CRC. This indicator is applicable in only CRC-4 framing modes.<br />

• E-Bit - A momentary indicator that responds to the E-bit.<br />

• Pattern - A momentary indicator that responds to a disruption of the incoming<br />

pattern.<br />

• Frame Slip - A momentary indicator that responds when the test set<br />

encountered a disruption of the incoming frame pattern.<br />
