A.Activate RDL. This may be done in two ways: first, by moving the front panel toggle switch UP to “RDL”. Second, by raising pin 21 on the interface. (Note: Make sure SW1-8 is OFF).

B.Perform a BER (bit error rate) test on the system.

C.If the BER test equipment indicates a fault, and the Local Analog Loopback test was successful for both Model 1035s, you may have a problem with the twisted pair line between the modems. You should then check the twisted pair line for proper connections and continuity.

5.3.3Using the V.52 BER Test Independently

The V.52 BER test can be used independently of the V.54 loopback tests. This requires two operators: one to initiate and monitor the test at the local Model 1035, and one at the remote Model 1035. To use the V.52 BER test by itself, both operators should simultaneously follow these steps:

1.Locate the “511/511E” toggle switch on the front panel of the 1035 and move it DOWN. This activates the V.52 BER test mode and transmits a “511” test pattern to the other unit. If any errors are present, the receiving modem’s red “Error” LED will blink sporadically. Note: For this test to function, the “511” switch on both Model 1035s must be on.

2.If the test indicates no errors are present, move the V.52 toggle switch UP, activating the “511/E” test with errors present. If the test is working properly, the receiving modem's red “Error” LED will glow. A successful “511/E” test will confirm that the link is in place, and that the Model 1035’s built-in “511” generator and detector are working properly.

5.4POWER-DOWN

Turn off the Model 1035 by unplugging the AC power adapter from

the wall. There is no power switch on the Model 1035.
