Test Patterns
Use the Test Pattern commands to send, monitor, and
abort transmission of test patterns on the DSU/CSU
network. Available test patterns are:
•
QRSS – A Quasi-Random Signal Source
approximating live data that can be monitored for
logic errors (on network and data ports).
•
1-in-8 – A test pattern consisting of a one (1)
followed by seven zeros (on network only).
•
511 – A Pseudo-Random Signal 511 bits long (on
data ports only).
Sending Test Patterns
Use the Send command to start transmission of a test
pattern.
Only one test pattern can be active at a time on one
port. Table 4-3 lists the valid send test pattern
combinations. Valid combinations are identified by YES.
To send a test pattern,
1. Press F2 to select Test from the top-level menu
screen.

If you press F2 to send a 1-in-8 pattern, skip
Step 5.
5. From the Send screen, press the function key that
corresponds to the network or port for which you
want to send a test pattern. Use the scroll keys, if
necessary. (NET does not appear for the 511
pattern.)

If the DSU/CSU is already sending the test pattern
you selected, the message Already active appears.
If selected an incompatible test pattern
combination, the message Invld Test Combo
appears. See Table 4-3 for valid combinations.
