Results can be cleared by pressing Clear (shift 9).
The results are accumulated until the test pattern is set
to None or Cleared.
The use of TST DS0s for testing can be very useful,
particularly in Fractional T1 applications. An end to end
test can be run on the Fractional DS0s by 1) setting for
Map B the TST in the same DS0 as used by Map A to
receive data from an Nx56/64 port and 2) by looping the far
end using a V.54 loopback code on the Nx56/64 port. In
addition, a single DS0 can be used for continuous testing
while other DS0s are passing normal data. This will also
provide an end to end check on the entire link. Set each end
to send QRSS in TST DS0s (using 1 DS0) and occasionally
view the results on the Pattern Result menu selection.
