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 1092’s
built-in “511” generator and detector are working properly.
NOTE: The above V.52 BER tests can be used independently
of the Remote Digital Loopback tests. This requires two
operators: one to initiate and monitor the tests at the local
Model 1092, and one to do the same at the remote Model
1092. In this case, the test pattern sent by each Model 1092
will not be looped back, but will be transmitted down the line to
the other Model 1092. While one operator initiates test, the
other monitors for errors.
