COMSPHERE 3800 Series Modems

Pattern

Pattern can transmit and receive a 511 bit error rate test pattern. It can also be used with a local analog loopback or a remote digital loopback to simulate data passing

through the modem. For this test to operate properly, the modems must be online and in Synchronous or Asynchronous Direct mode. Otherwise, the message Invalid:Bffr Mde appears when this test is started. (See Figures 8-4 through 8-6.)
