Maintenance Commands 6-35
Octel 200/300 S.4.1PB60019−01
Tone/DTMF/Beep Test
Use the TEST LINE 1 command to test line 1. To run the test, turn the terminal or teleprinter ON. At
the @ prompt, enter:
TE L 1
Enter
This test runs in sequence on each of the installed ports.
Use the TEST LINE 5 command to test line 5 for a specific port. At the @ prompt, enter:
TEL5x
Enter
For this command, x is the specific port number in HEX.
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 whether the tones sent 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 can cause the
Octel 200/300’s self-test to fail and place the Octel 200/300 port in TST (test) mode, taking the port out of
service. The port remains in TST mode until the self-test runs again and can put the port in service or until
the message server is restarted. In cases of conflict with PBX diagnostics, the self-test can be disabled in
the SLOTS Table. Consult with technical support before you set the self-test to NO in the SLOTS Table.
Ring Detection/PBX Connection Test
Use the TEST LINE 4 command for this test. To run the test, turn on the terminal or teleprinter. At the
@ prompt, enter:
TEL4x
Enter
For this command, x is the installed port number (in HEX) to be tested.
This test runs only on the port requested in the command, and the port must have the self-test parameter
in the 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 correctly connected to the PBX. These pulses trigger the
ring-detection circuitry on the port.
The test is completed successfully when the LIC reports the detection of this “ringing.” If ringing is not
detected, the test terminates unsuccessfully after 5 seconds and leaves the tested port in the TST mode,
removing the port from service. An error is also logged in the Hardware Error Table.
. Some PBXs are not capable of generating sufficient voltage or loop current quickly enough for the
test to succeed. One example is the Northern Telecom SL1. Consult with Technical Support if you
are uncertain whether a particular PBX supports this test.
