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.
Status Indicators
• E1 Pulses - The test set is receiving pulses at the receive jack. Frame pulses
alone are not sufficient to activate this indicator. There must be pulses present in
the payload field.
• HDB3 - A HDB3 pulse pattern was detected on the incoming signal at the
receive jack. Note that only certain patterns transmit HDB3 pulse patterns. The
pattern must contain at least 4 consecutive zeroes before a HDB3 pattern is sent.
The QRSS pattern will generate HDB3 while an idle E1 circuit transmitting all
1's will not.
• Frame Sync - A frame sync pattern matches the one specified in the setup
screen on the test set.
• Pattern Sync - The received pattern matches the one specified in the setup
