Chapter 1 General Troubleshooting

Verify Wiring from the ONS 15310-MA Shelf and DSX Wiring Panel

1.7.4.1 Reviewing the Results on the Handheld Receiver Screen

At the conclusion of the automatic test or if you press the EXIT TEST key, the handheld receiver enters

the manual mode. Press DISPLAY to recall on the screen the last automated test results. Only “failed”

ports are shown. Ports that either pass or are untested do not appear on the screen. Each time the

DISPLAY key is pressed, the next test result appears.

1.7.4.2 Sending the Results to a Computer

After the automatic test is complete and the handheld receiver is again in manual mode, the handheld

receiver can send the stored results to a computer. The report is in the form of a standard text file.

Step 1 Using the supplied cable with DB9 female connectors at each end, connect the handheld receiver’s

EIA 232 port to a computer.

Note The handheld receiver operates as a data communications equipment (DCE) device. A straight

through DB9 cable is used (pin 2 to pin 2, pin 3 to pin 3, pin 5 to pin 5).

Step 2 Set up the computer’s serial port for 9600 baud, 8 data bits, no parity, and one stop bit.

Note See the instructions for your computer for the appropriate software and terminal mode set up.

Step 3 Press the MENU key once. The DSX wiring selection menu appears.

Step 4 Press MENU a second time. The test report menu appears.

Step 5 Press ENTER/ACCEPT to send the test result out the EIA 232 port.

Step 6 Wait for completion, or press EXIT TEST to abort the report. At 9600 baud the report takes only a few

seconds to transmit. Either the most recent or both stored reports can be sent.

The handheld receiver returns to manual mode. Each port will have a result, either “OK,” an error result,

or “UNTESTED.” The test reports are stored in non-volatile memory and saved until overwritten by the

next test activity; this allows you to power down the handheld receiver while retaining the reports for

later transmission to a computer.

There are blank lines in the test report format that you can edit to enter name, time, date, shelf locations,

and so on. The test report text file may be edited with any convenient software program after being sent

to a computer.

1.7.5 Perform Loop Tests

The TST-DSX card has limited capability for loopback testing with a commercial DS-1 or DS-3 test set.

The handheld receiver is not used in the LOOP testing mode.

The TST DSX has passive loop circuitry with no recovery and regeneration of signals. The loop path

through the ONS 15310-MA shelf and the TST-DSX card has insertion loss, which reduces the voltage

amplitude of a looped signal. The cable length between the DSX wiring panel and the shelf also
