5.3.3 Using the V.52 (BER) Test Pattern Generator
To use the V.52 BER tests in conjunction with the Remote Digital
Loopback tests (or with Local Line Loopback tests), follow these
instructions:
1.
Locate the “511/511E” toggle switch on the front panel of the
1092A and move it UP. 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
sporadically.
2.
If the above test indicates no errors are present, move the
V.52 toggle switch DOWN, activating the “511/E” test with
errors present. If the test is working properly, the local
modem's red “ER” LED will glow. A successful “511/E” test
will confirm that the link is in place, and that the Model
1092A’s built-in “511” generator and detector are working
properly.
