Test Pattern
QRSS Pattern
The QRSS pattern is commonly used to simulate real data in T1 interfac-
es. This pattern can be assigned to appear in all DS0s or only in
TST
DS0s . When QRSS is set in all DS0s and one of the network loopbacks
previously described is activated at the far end, a total end-to-end integ-
rity check can be run without the need for any external test equipment.
When QRSS is assigned to
TST DS0s , an integrity check of the link can
be run along with normal data flow. The TST DS0s are user assigned as
part of the DS0 Map.
This sets the pattern for the test and initiates the transmission of the pat-
tern. The test is terminated by selecting None. The following patterns
are available:
QRSS always runs at 64K/DS0.
Example:
1. Use the up and down key to select QRSS ALL DS0s .
2. Press Enter to record the selection. The TSU 600 starts to generate a
QRSS test pattern and inserts the pattern into all DS0s.
3. Select None to end the test.
Pattern Description
All Ones Sends an all ones pattern to the network
All Zeros Sends an all zeros pattern to the network
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
