Send and Monitor Pattern Tests

The pattern tests enable a DSU/CSU to either send or monitor a known bit pattern.
These tests generate industry-standard bit patterns that can be used to determine
whether information is being correctly transmitted across a circuit.
The following test patterns are available:
— QRSS
—
—

A Send Pattern test cannot be started when any loopback is running on the same
interface.

2. Select the desired pattern in the Send or Monitor field. If sending/monitoring a
user-defined pattern, enter the desired 2-byte hexadecimal value in the field
next to Send or Monitor.
When sending a pattern, the Inject ERR function key appears. Use Inject ERR
if you want to inject a bit error in the transmitted bit pattern.
3. Highlight the Send command to send a pattern, or the Start command to
monitor a pattern, and press Enter to start the test or start monitoring it.
4. View the length of time that the test has been running in the Results column.
An error count is also displayed. When monitoring a pattern, the ResetMon
virtual function key appears. ResetMon resets the error count to zero.
5. Highlight Stop and press Enter to stop the test.
