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. Otherwise, the message
Invalid Command
appears when this test is
started (Figures 3-7 through 3-9).
