Use the scroll bar to view those digital signals not currently in the window. Up to
twelve states (samples) are shown, with the most recent sample added to the left
of the display and the right-most sample deleted.
The time interval appears along the first row of each column. Each time interval
indicates the number of seconds between samples and varies depending on
other tasks currently running within the network. A time interval of 00 indicates
the beginning of a sequence.
The legend at the bottom of the window indicates the colors for Signal On (a
digital one or high), Signal Off (a digital zero or low), and Signal Changing
(transit or changing during the sampling). The DTE status information is obtained
by the device and displayed when polled by NMS. See the device’s user’s guide
for additional information.
To pause (freeze) the display, choose Pause. The display stops updating the DTE
status and Resume replaces Pause. To continue updating the display, choose
Resume.
VF Status
To view the condition of the communications line, choose VF Status from the
Status pull-down menu. The VF Status command displays the VF Status window.
