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:
A Send Pattern test cannot be started when the following tests are running:
T Any Loopback on the same interface.
T Send Pattern Test on any port assigned to this network interface.
T Send V.54 or FT1 Loopback, or Data Channel Loopback on any synchronous
data port (Port Use set to Synchronous) and assigned to this network
interface.
Procedure
To send and monitor a Pattern Test:
1. Follow this menu selection sequence:
Main Menu
→
Test
→
[Network Physical Tests/DSX-1 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 InjectERR function key appears. Use InjectERR
if you want to inject a bit error in the transmitted bit pattern.
3. To send a pattern, highlight the Send command to send a pattern and press
Enter.
To monitor the test, highlight the Start command and press Enter.
The length of time that the test has been running is shown in the Result
column. An error count is also displayed. When monitoring a pattern, the
ResetMon function key appears. ResetMon resets the error count to zero.
4. To stop the test, press Enter to send the Stop command. Start reappears
and the status of the test changes back to Inactive .
