Note Used with a remote receiver, the TST-DSX card indicates whether the wiring connections are valid, which allows users to take corrective action prior to turning up service. The TST-DSX card is normally used in systems where there are no working services and likely no power applied. A hand-held remote receiver module is used with the TST-DSX card and is plugged into the DSX panel during testing using the provided cables. The receiver allows the user to initiate tests, display test status and errors, and store test results that can be transferred to a PC over an EIA-232 connection.



Caution The goal of this procedure is to test the wiring between the DSX and an empty Cisco ONS 15310-MA shelf assembly. The wiring type is DS-1 or DS-3. There must be no DS-1 or DS-3 traffic on the side of the shelf being tested. The TST-DSX card disrupts service if it is plugged into a shelf side where a
DS-1 or DS-3 card is carrying traffic.


Step 1 Insert the TST-DSX card into one of the expansion slots on the shelf (either Side A, Slot 1 or 2, or Side B, Slot 5 or 6).

Step 2 If the shelf power is on, continue with Step 3. If the shelf power is not on, plug the supplied AC-to-DC adaptor into a wall outlet and plug the barrel connector of the power cable into the 48 VDC jack on the TST-DSX card faceplate.

Step 3 Set the TST-DSX card faceplate switch to the NORMAL position.

Step 4 Verify the state of the LEDs on the faceplate:

POWER is steady on.

ACTIVE blinks slowly, indicating that the TST-DSX is functional.

LOOP is off.

Step 5 Verify that the backplane wiring and connectors have been installed.


Note If the ACTIVE LED is blinking rapidly, the Backplane Interface Connector (BIC) is not present.


Step 6 Turn on the power switch of the handheld receiver and observe the display.

The first display shows the receiver version number. The next display shows the following:
MANUAL TEST MODE
DS3; A; 310

The last display shows either the DS-1 or DS-3 test mode and the status of the test.

Step 7 If the display indicates 454 instead of 310 as the shelf mode, press the MENU key six times, press DISPLAY to change from 454 to 310 shelf mode, and then press the ENTER/ACCEPT key to save the setting.

Step 8 To change from one cable type to another (DS-1 or DS-3), press the MENU key once, press DISPLAY to change the setting, and then press ENTER/ACCEPT to store the setting.

Step 9 At the DSX wiring panel, insert an appropriate patch cord into the handheld receiver.

Step 10 Insert the other end of the patch cord into a port on the DSX wiring panel. The control unit's screen continuously shows the test result of any detected signal.


Note For more detailed information on using the TST-DSX card to verify and troubleshoot wiring between the ONS 15310-MA shelf and the DSX wiring panel, see the Cisco ONS 15310-CL and Cisco ONS 15310-MA Troubleshooting Guide.


Stop. You have completed this procedure.
