Functional Description
No threshold is selectable for the capacitance since no alarm will be gener-
ated. The measured value will be displayed only.
When changing the threshold values the line-test status will be adapted
accordingly without running the test again. You just have to press the “Apply”
or “Refresh” button in the port status window.
The alarm threshold configuration is valid for cyclic and manual line-tests.
5.11.4 Line-test Results
The line-test lasts about 10 seconds for each subscriber.
The results of the line-tests are displayed in the port status on the “Line Test”
tab individually for every subscriber port.
Each result is displayed with a time stamp. The date and time stamp shows
when the subscriber was last tested.
The resulting line-test status is displayed as follows:
• Requested
In this phase the SUPM1 checks the subscriber line for its state (on-hook
/ off-hook).
If a subscriber is on-hook the user port is set to the locked state (V5CAS
mode of operation only). If the subscriber is off-hook the user port is left
in the unlocked state until the subscriber goes on-hook. If by this time the
line-test timeout has not occurred the user port is set to the locked state.
• Rejected
Indicates a busy subscriber line and therefore the line-test was not exe-
cutable or the line-test timeout has occurred
• Running
This means that the line-test for this particular subscriber is ongoing.
•Passed
The result of that specific test is within the thresholds. If all test results of
the subscriber are passed then the subscriber line is usable.
• Failed
The result of that specific test is out of the thresholds and therefore a
problem may be present on that subscriber line.
A failed line-test is reported as an alarm on the port layer.
• Aborted
This text is displayed if a line-test is stopped manually.
• See results
This state indicates that a particular test could not be executed due to
any abnormal line conditions. The line-test results window status shows
in this case “untestable”. The conditions for untestable items are:
− Isolation < 5 kΩ:
Capacitance is untestable,
Noise is untestable.
− Foreign AC voltage > 10 V:
Isolation is untestable,
Capacitance is untestable,
Noise is untestable.
