Octel 200/300 S.4.1PB60019−01

Use the TEST LINE 1command 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 commandto test line 5 for a specific port. At the @ prompt, enter:

TEL5x Enter

For this command, xis the specific port number in HEX.

A hybrid transformer is used on the LICto 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.

Use the TEST LINE 4 commandfor this test. To run the test, turn on the terminal or teleprinter. At the

@ prompt, enter:

TEL4x Enter

For this command, xis 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.
