Patton electronic 1082/F 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 continu- ously.

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.
