6.3 TEST MODES
The Model 1082/I and Model 1082/144/I has a built-in proprietary loop-
back test mode, plus a built-in V.52 BER test pattern generator, for evalu-
ating the condition of the modems and the communication link. These
tests can be activated physically from the front panel, or via the interface.
Remote Digital Loopback (RDL)/V.52 (BER)
The Remote Digital Loopback (RDL) test checks the performance of both
the local and remote Model 1082s, and the communication link between
them. Any characters sent to the remote Model 1082 in this test mode
will be returned back to the originating device (see Figure 7, below). For
example, characters typed on the keyboard of the local terminal will
appear on the local terminal screen after having been passed to the
remote Model 1082 and looped back.
