Pattern

Pattern can transmit and receive a 511 bit error rate test pattern. It can also be used with a currently running local analog loopback or a remote digital loopback to simulate data passing through the modem. You will need to start the local analog or remote digital loopback test before you start the pattern test. For this test to operate properly, the modems must be online and in Synchronous or Asynchronous Direct mode (Figures 8-4 through 8-6).
