•
SYNC LOSS: Indicates the number of times that the equipment lost sync respectively to
the receive signal.
•
FAS LOSS: indicates the total number of frame sync losses flagged when the test is
running.
•
CAS LOSS: indicates the total number of multiframe sync losses flagged when the test
is running. For PCM30 and PCM30C only.

•
CRC LOSS: indicates the total number of CRC sync losses flagged when the test is
running.
•
PAT LOSS: Indicates the number of pattern sync losses. This means the desired pattern
is not being received.
•
ALL ONES: Keeps track of the seconds during which the receive signal is always 1.
•
ALL ZEROS: Keeps track of the seconds during which the receive signal is always 0.
•
REMOTE ALARM: Indicates the number of times that the remote alarm was sent. When
there is frame sync loss, timeslot 0 bit A is set on the even frames, which indicates the
occurrence of remote alarm.
•
RMF ALARM: Indicates the number of times that the multiframe remote alarm was
sent. When there is multiframe sync loss, timeslot 16 bit 6 (for frame 0) is set, indicating
multiframe remote alarm.
5.2.4 - Histograms
The histograms are graphic representations of the number of errors or alarms versus time.
For each kind of error or alarm that can occur within a given configuration, one histogram is
displayed. Each histogram column displays the number of errors or alarms that occurred per minute,
or per hour, according to the chosen resolution.
The histogram screens are accessible during the test, or by visualising the memory. To see
the histogram from the OK screen, press <F4> (HISTO). From the Menu screen, place adequately
the cursor and press <F4> (ENTER). The first histogram displayed is always the errored bits
histogram, as in the figure below.
