PATTERN
This sets the pattern for the test and initiates the
transmission of the pattern. The test is terminated by
selecting None. The following patterns are available:
QRSS All DS0s Generates a QRSS test pattern
and inserts the pattern into all
DS0s
QRSS TST DS0s Inserts a QRSS pattern in those
DS0s mapped as TST in the
currently active map (A or B)
None Terminates pattern generation
All ones Inserts an all ones test pattern
into all DSOs
All zeros Inserts an all zeros test
pattern into all DSOs
QRSS always runs at 64K/DS0.
Use the up and down scroll to select, for example,
QRSS ALL DS0. Press Enter to record the selection.
The
TSU 600 starts to generate a QRSS test pattern and
inserts the pattern into all DS0s.
To end the test, select None.
PATTERN RESULT

Figure 3-21. Leaving and returning to this menu item

Code (version K or later): Pressing 2 injects errors into the
test pattern. These errors are detected by the device per-
forming the pattern check.
