4.1.2 Status bar
The status bar is used for displaying the status information for pattern sync, defect
notification and anomaly/defect injection. The elapsed time of the test in hrs:min:sec
format is shown in position k. If a test is not running, the elapsed time of the previous
test will be displayed. Position l shows how long the test will run. (See Section 4.6 to
set the duration of the test.)

Rx Icons
The pattern sync icon (position a) displays a steady synchronised digital
signal if the instrument is synchronised on a BERT pattern.
The pattern sync icon displays an animated unsynchronised digital signal
if the instrument is unable to synchronise on a BERT pattern. This defect
is also known as LSS (Loss of Sequence Synchronisation).
The pattern sync icon is blanked if no BERT pattern is present or there
are no containers selected to carry a BERT pattern.
The defect detected icon (position a) flashes if any other defect condition
is currently being detected at the selected Rx input, such as LOS.
The OK icon (position b) is displayed if no alarm or error conditions have
been detected at the se+++lected Rx input, since the beginning of the
test. It is linked to the large OK displayed on the screen and will also be
displayed if the results are cleared by pressing the Reset function key. As
soon as an alarm or error condition is detected the icon will be blanked
and the large OK displayed on the screen will be replaced by another
results panel showing the condition detected.
(position c) is displayed depending on the type of performance analysis
chosen. For example BIT will be shown if G.821 is selected.
Assuming the ATM option has been purchased and enabled (see Section
6) this icon (position d) becomes animated when load ATM traffic is
monitored at the receiver (Rx).
