QRSS Pattern
The QRSS pattern is commonly used to simulate real data in E1
interfaces. This pattern can be assigned to appear in all TS0s or
only in TST TS0s. When QRSS is set in all TS0s and one of the net-
work loopbacks previously described is activated at the far end, a
total end-to-end integrity check can be run without the need for
any external test equipment. When QRSS is assigned to TST TS0s,
an integrity check of the link can be run along with normal data
flow. The TST TS0s are user assigned as part of the TS0 Map.
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 always runs at 64K/TS0.
For example, use the up and down arrows to select QRSS ALL
TS0s. Press Enter to record the selection. The ESU 120e starts to
generate a QRSS test pattern and inserts the pattern into all TS0s.
To end the test, select None.
QRSS All TS0s Generates a QRSS test pattern and inserts the
pattern into all TS0s
QRSS TST TS0s Inserts a QRSS pattern in those TS0s mapped as
TST in the currently active map (A or B)
None Terminates pattern generation
