The INADS Link test attempts to call an alarm receiver (in the background) to verify the communications link with the alarm receiver. When a user enters test inads-link, the system immediately returns either a Command successfully completed or Command failed message.
The Command successfully completed message means the switch will attempt to call the alarm receiver in 2 minutes. This test runs even if Alarm Origination is disabled. The 2-minute delay provides enough time for a remote technician to hang up the call and thus free up the alarm receiver’s line so that the customer’s switch can call the alarm receiver back. The system displays Command failed message if:
A previously entered test inads-link is in progress.
The system is attempting to report active alarms to the alarm receiver.
As any error conditions are encountered during the test, they are logged against the INADS Link MO.
If the initial test result was Command successfully completed, any logged error codes would range from 1–9.
If the initial test result was Command successfully completed, any logged error codes would be 10 or 11.
An error is logged at the alarm receiver even if the call to the alarm receiver finally succeeds. The alarm receiver’s software:
Recognizes this special test inads alarm type.
Automatically opens and closes a trouble ticket.
Within the trouble ticket, a field containing the description TESTING INADS LINK indicates that the ticket was initiated by test inads-link.
After entering the command, up to 9 minutes can elapse before the switch places the call and the alarm receiver responds. To determine whether the call was successful, the error lLog should be examined by using the inads category 10 minutes after successfully entering the command.
