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

Displays the results of the test currently active. See
Figure 3-21. Leaving and returning to this menu item
does not interrupt the test.

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.
