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.

2. From the Test screen, press F3 to select Ptrns.

Test:

3. From the Patterns screen, press F2 to select Send.

4.From the Patterns Send screen, press F1 to send a QRSS pattern, or F2 to send a 1-in-8 pattern, or F3 to send a 511 pattern.

Patterns: Send

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.
