Send and Monitor Pattern Tests
The pattern tests enable a FrameSaver unit 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 — 511
— All-zeros — 2047
— All-ones — 2E15-1 (2
15
-1)
— 1-in-8 — 2E20-1 (2
20
-1)
— 3-in-24 — User-defined 2-byte test pattern (a0a0)
— 63
A Send Pattern test cannot be started when the following tests are running:
H Any Loopback on the same interface.
H Send FT1 Loopback or Data Channel Loopback on the synchronous
data port.
" Procedure
To send and monitor a Pattern Test:
1. Select Network Physical Tests.
Main Menu
→
Test
→
Network Physical Tests
2. Select the desired pattern in the Send or Monitor field. If sending/monitoring
a user-defined pattern, enter the 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.
6. View the length of time that the test has been running in the Result column.
