When a SignalTEK II Remote Unit is directly connected but no active network is detected, select the
TESTS icon from the home screen (Fig 36) to view the tests available, Fig 37.

After any one of the three available tests is selected from the menu, the soft keys RUN and SETUP will
appear:
Wiremap and Autotest are described in Tests menu description
– Cable mode
. When Wiremap is run in
Ethernet mode, the only difference is that the cable to be tested is not connected to an Active Remote but
to either the Remote Unit or an active network port.
Cable performance
Fig 38
When a cable performance test is run, back-to-back frames are
transmitted to the Remote Unit which loops them back to the Near-End
Unit where they are checked and counted.
Fig 38 shows the result screen of a successful cable test.
Frame Size
,
which is fixed, is stated for information.
Tx
states the number of frames
transmitted, the associated green indicator bar confirms that 100% of
the frames were sent. As the frame size (and fill) is fixed, the number
of frames transmitted is dependent on the duration of the test only.
Rx
states the number of frames received, the green indicator bar confirms
that 100% of the transmitted frames were received. As all transmitted
frames were received,
Error
states 0 and its associated indicator bar
remains uncolored and shows 0%. When there is a discrepancy
between the number of transmitted and received frames,
Error
states
the number of errored frames and the indicator bar is partly colored red
proportional to the number of errored frames. However, the cable will
still pass the test provided the Frame Threshold is not exceeded (see
Setup
page 16).
