The originating ISU 512e generates the 2047 patterns and checks the
incoming pattern for errors. The test is run for 120 seconds. The results
of the test are placed in the status buffer of the originating unit.
In addition, the ISU 512e can loop back a remote unit automatically at
the start of a BONDING call and run the 2047 pattern. This is accom-
plished through a smart dial string: <number> #5.
For example, the dial string 9224323#5 places a remote loopback call
to the remote unit. After BONDING connects, the originating unit dis-
plays the byte count and error count for the current test along with the
amount of time left in the test. The remote unit remains in protocol
loopback and displays the amount of time left before the unit(s) enter
data mode. This allows the originating side to complete the test and
write the results to the status buffer.
