The following example test all regions on disk #1.
If any errors are reported, refer to the Hardware Errors section in this chapter.
■
Line Interface Card (LIC) Diagnostics
Two on-line diagnostic tests may be used to test the LICs. The first test described is performed
periodically during normal system operation. It is used to check the analog (voice) path of the LIC.
The second test described is the ring-through test.
■
Tone/DTMF/Beep Test
To run the test, turn ON the terminal or teleprinter. At the @ prompt enter:
TEST LINE 1 (or TE L l)
This test runs in sequence on each of the installed ports.
To test a specific port, at the @ prompt, enter:
TEST LINE 5 X (or TE L 5 X)
A hybrid transformer is used on the LIC to check tone generation and detection circuitry. A tone
is applied to the hybrid transformer and, as it is being reflected, the tone detector is turned ON. A
comparison is made to see if the tones match the tones detected. The test sequence continues
through all assigned ports. If a test tone sent is not received correctly, an error is entered in the
Hardware Error Table.
Some PBXs have the capability of running diagnostics on their ports. The diagnostics may cause
the VP 300’s selftest to fail and place the VP 300 port in TST mode, taking the port out of service.
The port remains in TST mode until selftest runs again and is able to put the port in service, or
until the system is restarted. In cases of conflict with PBX diagnostics, selftest can be disabled in
the SLOTS Table. Consult with Toshiba prior to defining NO to selftest in the SLOTS Table.

Ring Detection/PBX Connection Test
To run the test, turn on the terminal or teleprinter. At the @ prompt, enter:
TEST LINE 4 PP (or TE L 4 PP)
