5.2.3 USING 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 1140, and one at the remote Model 1140. To use the V.52 BER test by itself, both operators should simultaneously follow these steps:

1.Locate the "511/511 E" toggle switch on the front panel of the 1140 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 1140s 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 1140's built-in "511" generator and detector are working properly.

5.3POWER UP

Once the Model 1140 is properly installed, it should operate transparently—as if it were a standard cable connection. Since operating power is derived from the RS-232 data and control signals; there is no "ON/OFF" switch. All data signals from the RS-232 interface are passed straight through.
