Audio Path Test (APT) and Parameters
The purpose of APT is to send a specific audio tone from the earpiece or speaker of a telephone and then
check that it is correctly received by the microphone. This will then verify that both microphone and
speaker are functioning. APT is enabled as a factory default but must be turned on to function.
APT appears as an alarm on the ALARMS page, and can be set to report via Syslog and / or email like
any other alarm, with some differences as listed below. The test can be set to run automatically or
triggered manually using the parameter controls listed in Table 4.
Table 4. APT Parameters
Parameter Function
APTENABLE Sets whether APT is ON or OFF .
APTTIME Sets a start time (24-hour clock) and test interval (in hours). This field should
contain: first, the time in hours and minutes separated by a colon (:) followed
by a comma (,) followed by the interval in hours (range 1–24).
Automatic testing will start at the specified time and repeat every specified
interval until 00:00 midnight the next day.
The cycle will then repeat the next day and so on.
Default:
00:00,24 meaning that the test will perform once per day at
midnight.
APTCOUNT
Sets the number of tests that will be performed at each interval.
Range is 1–10.
Default: 1 (but it can be increased to repeat the test at each interval.)
APTOKCOUNT Sets the number of tests that must pass at each interval to be classed as a
successful test. APTOKCOUNT must always be <= APTCOUNT.
For example, if APTCOUNT were set to 3 and APTOKCOUNT to 2, the test
would be deemed to have passed if 2 pass readings out of 3 were recorded.
This feature is to allow for potential disruption in areas of high ambient noise.
Default value: 1
APTREPORT Sets whether or not APT will send reports every time the test passes.
Normal alarms only report if they change state. Setting APTREPORT to ON
will cause the telephone to send a regular report confirming that its acoustic
components are healthy.
By inference, this report also confirms that the telephone is powered, running
and connected to the network, so it also provides a useful general health
check.
If the test fails, the telephone will not send repeated reports until at least
APTOKCOUNT tests pass again.
APTNOW APT now will start an APT test within 60 seconds. This button will only start
a test if APTENABLE is set to
ON .
