Pseudorandom Bit Sequence (PRBS) Testing

To test using PRBS, configure the IE-iMcV-T1/E1/J1-LineTerm, TP/SFP modules for No Loopback, and then configure the Transmit Copper Data Source to PRBS. Configure the local device for Loopback and start the test. Verify the PRBS LED is ON indicating no errors are being received.

Installation Troubleshooting

General Troubleshooting

•The copper port can easily be tested using the internal PRBS signal generator and detector and a physical wire loop on the copper interface.

•The fiber port is internally tested at all times by a working pair of units. With one unit configured for Local Management (S3-2 set OFF) and the other for Remote Management (S3-2 set ON), the fiber line is verified if the RM LED is ON at both ends of the fiber line. Under normal operation only the RM LED is ON at both HOST and REMOTE.

•To test a media converter by itself, first verify that the fiber patch cable is appropriate, then follow these steps to test:

1.Connect the media converter to the RJ-48 device with a copper cable.

2.Loop a single strand of fiber from the transmit port to the receive port of the media converter.

3.Verify that there is a valid connection for both the RJ-48 and fiber ports on the media converter. (No ER or LOS LED ON)

•If there is trouble with link connectivity, verify that the cable connection and DIP Switch settings are correct.
