5.3.4 V.52 BER TEST GENERATOR
The Model 1094 has a
1.Locate the 511/511E toggle switch on the front panel of the Model 1094 and move it DOWN. This activates the V.52 BER test mode and transmits a 511 pseudorandom test pattern to the other unit. If any errors are received, the receiving Model 1094’s red ER LED will blink sporadically.
NOTE: For this test to function, the 511 switch on both Model 1094’s must be on.
2.If the test indicates no errors are present, move the V.52 toggle switch UP, activating the 511/E test. The 511/E test transmits the 511 pseudorandom test pattern and injects intentional errors about once per second. If the test is work- ing properly, the receiving Model 1094’s red ER LED will blink regularly.
A successful 511/E test will confirm that the link is in place, and that the Model 1094
3.This test can be done by one operator by first activating the local analog loop or remote digital loop.
