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.
Recv Level - The voltage level of the signal measured at the Rx jack.
Frequency - The frequency of the signal measured at the Rx jack. The E1 Pulses indicator must be active for this measurement to be displayed.
Elapsed Time - Indicates the amount of elapsed time since the last measurement reset.
BPV Errors - A tally of the number of BPV errors since the last measurement reset.
BPV Error Rate - The percent ratio of BPV errors to total bits transmitted since the last measurement reset.
BPV Errd Secs - The number of one second intervals since the last measurement reset that contained BPV errors.
Frame Errors - A tally of the number of Frame errors since the last measurement reset.
Frame Error Rate - The percent ratio of frame errors to total bits transmitted since the last measurement reset.
Frame Errd Secs - A tally of the number of one-second intervals since the last measurement reset that contained frame errors.
Signal Loss - A tally of the number of one-second intervals since the last measurement reset that contained signal errors.
Frame Sync Loss - A tally of the number of one-second intervals since the last measurement reset that contained frame sync loss.
Excess Zeros - A tally of the number of one-second intervals since the last measurement reset that contained excess zeros.
All 1's - A tally of the number of one-second intervals since the last measurement reset that contained the AIS pattern.
Error Free Seconds - A tally of the number of one-second intervals that were error free since the last measurement reset.
Errored Seconds - A tally of the number of one-second intervals since the last measurement reset that contained errors such as BPVs and frame errors.
Severe Errored Seconds - A tally of the number of one-second intervals since the last measurement reset that were severely errored.
Available Seconds - A tally of the number of one-second intervals since the last measurement reset that were available for service.
Unavailable Seconds - A tally of the number of one-second intervals since the last measurement reset that were unavailable for service.
Degraded Minutes - A tally of the number of one-second intervals since the last measurement reset that were degraded.
Slip Rate - The percent ratio of frames cycle slips of the incoming signal relative to the slip reference choice on the setup menu - since the last measurement reset.
Peak + Wander - The peak amount of positive wander, measured in bit intervals, since the last measurement reset.
Peak - Wander - The peak amount of negative wander, measured in bit intervals, since the last measurement reset.
+Frame Slips - A tally of the number of positive frame slips that occurred since the last measurement reset.
-Frame Slips - A tally of the number of positive frame slips that occurred since the last measurement reset.
Bit Errors - A tally of the number of bit errors that occurred since the last measurement reset.
Bit Error Rate - The percent ratio of bit errors to total bits transmitted since the last measurement reset.
Pattern Sync Loss - A tally of the number of times the pattern detector lost synchronization since the last measurement reset.
Test Data Rate - The measured data rate of the bit stream.
