where PP is the installed port number to be tested.
This test runs only on the port requested in the command, and the port must have the selftest
parameter in the PORT/SLOT Table set to YES.
This port is rapidly seized and released repeatedly. This action causes charging and discharging of
the tip and ring circuitry on the LIC if the port is properly connected to the PBX. These pulses
trigger the ring detection circuitry on the port.
The test completes successfully when the LIC reports the detection of this "ringing" to the CPU. If
ringing is not detected, the test terminates unsuccessfully after five seconds and leaves the tested
port in the TST mode, removing the port from service. An error is also logged to the Hardware
Error Table.
☞
Some PBXs are not capable of generating sufficient voltage and/or loop current quickly
enough for the test to be successful. Consult with Toshiba Technical Support if uncertain
that a particular PBX supports this test.
■
Ring – Through Test
A ring-through test can also be used. This test runs only on demand and should only be used when
the VP 300 is initially installed or when it is known no calls are being processed.
The ring-through test performs as follows:
•
Seizes a port.
•
Waits for dial tone from the PBX.
•
Dials a port using the extension number entered in the SLOTS Table.
•
Waits for the port to answer, and sends a test pattern.
For example, a 4-port system makes 12 test calls, each test call takes 20 to 30 seconds to
complete. If the port called is busy or does not answer, an error is logged in the Hardware Error
Table. To initiate this test, at the @ prompt, enter:
TE L 2
