Pattern Result
Displays the results of the test currently active. Leaving and returning to
this menu item does not interrupt the test.
Pressing 2 injects errors into the test pattern. These errors are detected
by the device performing the pattern check.
Clear results by pressing Shift 9. The results are accumulated until the
test pattern is set to None or Cleared.
Using TST DS0s for testing can be very useful, particularly in Fractional
T1 applications. You can run an end-to-end test on the Fractional DS0s
by:
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.
Pattern Description
ES The number of seconds with at least 1 bit error
BES The number of seconds with more than 1 bit
error and less than 320
SES The number of seconds with more than 320 bit
errors
SYNC Indicates if pattern sync is (yes) or is not (no)
valid. An asterisk (*) indicates if pattern sync
has been lost since the start of testing
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 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.
