Patton electronic 1082/144 user manual Using the V.52 BER test pattern generator

Using the V.52 (BER) test pattern generator

To use the V.52 BER tests in conjunction with the Remote Digital Loop- back tests (or with Local Line Loopback tests), do the following:

1.Locate the 511/511E toggle switch on the front panel of the Model 1082 and set the toggle to the down position. This activates the V.52 BER test mode and transmits a 511 test pattern into the loop. If any errors are present, the local modem’s red ER LED will blink continuously.

2.If the above test indicates that no errors are present, move the V.52 toggle switch to the up position, activating the 511/E test with errors present. If the test is working properly, the local modem’s red ER LED will blink. A successful 511/E test will confirm that the link is in place, and that the Model 1082’s built-in 511 generator and detector are working properly.
