Send and Monitor 511 Pattern
The Send command is used to send a test pattern over the DSL interface. This
test commands the remote unit to start sending and monitoring a 511 pattern, and
then sends and monitors a 511 pattern. Ones are sent in the time slots that are
mapped to the DSL port that is in test.
Pressing Enter after selecting the Send and Monitor 511 Pattern Start command
from the DSL & G.703 Tests menu initiates the test. The result field initially
displays
hh:mm:ss - Out of Sync
, where
hh:mm:ss
is the time that the test
has been running. The error count displays Out of Sync until the unit has detected
the 511 pattern.
Once the pattern is detected, the error count field is updated once every 10
seconds. It is displayed as a five-digit number with the maximum count being
99999.
The Send and Monitor 511 test is not a loopback test. Each unit independently
sends and monitors a 511 pattern.
Acitivating a Send and Monitor 5111 test causes the EOC (used for management)
to be lost to the remote unit.
Procedure
To run a Send and Monitor 511 test:
1. Allow the modem to fully train up with its partner modem for at least a minute.
2. Position the cursor at the Start command next to Send and Monitor 511 on the
DSL & G.703 Tests screen.
3. Press Enter. If the test begins successfully, the Start command is changed to
Stop. Else:
— If the DSL interface is down when Start is selected, no action is taken.
— If the unit is already sending a test pattern on the DSL interface, then
Invalid - Send Pattern Already Active appears on line 24.
— If any loopback test is active, an Invalid Test Combination error message
appears on line 24.
4. To manually stop the test, verify that the cursor is positioned at the Stop
command, and press Enter.
The result field remains until another Send test is started. The DSL interface
retrains after the test is stopped.
