HLXC AND HLXR END-TO-END TESTS

Summary: This procedure provides instructions for using a DS3 test set (with DS1 option) to verify that error-free data is received from the HLXC module at the HLXR module.

Caution: Modules can be damaged by electrostatic discharge (ESD). Before handling any modules, ESD protection must always be used. Ensure that all modules removed from the chassis or not installed are properly stored in anti-static packing material. When working with modules, always place the module on an electrically-grounded, approved, anti-static mat.

Note: Press CONTROL-A for help information on moving around and editing fields.

1.Connect a DS3 test set (with DS1 option) to the cross-connect or to the RX and TX connections at the rear of the chassis. See Figures 520-1and 520-2.

2.Identify the HLXC module corresponding to the DS1 circuit to be tested.

3.Identify the HLXR module corresponding to the DS1 circuit to be tested.

4.Connect the DS1 Test Set RX to the NET OUT jack on the front panel of the HLXR module.

5.Connect the DS1 Test Set TX to the NET IN jack on the front panel of the HLXR module.

6.Using the Craft Interface, verify that the DS3 MUX is EQUIPPED and is IN SERVICE.

7.Using the Craft Interface, verify that the HLXC module to be tested is EQUIPPED and IN SERVICE and the DS1 to be tested is PROVISIONED and IN SERVICE.

Reference: DLP-531HLX Configuration

8.Insert a test signal into the DS1 to be tested using the DS3 test set with DS1 option.

9.Verify that all alarm indicators on the chassis are out and the DS1 test set at the HLXR module NET OUT jack is receiving error-free data for the DS1 test signal selected.

10.Insert a DS1 test signal into the HLXR module NET IN jack using the DS1 test set.

11.Verify that all alarm indicators on the chassis are out and the DS3 test set with DS1 option is receiving error-free data in the DS1 selected for test.

12.Repeat procedure starting at Step 2 for all HLXC modules to be tested.

13.Record test results and update office records following local office practices.

Stop! You have completed this procedure.
