Connect a cable from the DS3 test set
receive
connection to the OUT jack of the DSX-3
associated with the first DS3 or TMUX tributary of the 1665 DMX Function Unit slot to
be tested.
Result:
The DS3 test set should indicate it is receiving an error free PRBS signal. To
verify that the port on the DS3 or TMUX pack is receiving the signal, verify that the
port has transitioned to an "in service" state with the
View -> Equipment
command.
A port state of "IS" indicates that the pack is receiving a good signal to the port.

While observing the error-free transmission at the DSX, grasp the DS3 cable about two
inches from the BNC connector head and gently rotate (twist) the cable in a clockwise and
counter clockwise direction about 45 degrees (gently).
Result:
If any errors are detected while performing this “wiggle test,” the BNC
connector must be cut off and replaced.
If an error-free signal is not received:
•
Check the LBOs settings using the
View -> Equipment
DS3/EC1 and TMUX LBOs (p. 4-5)
•
Verify that the pack is provisioned for the framing format being sent from the test set,
M13.
•
Verify that the port is provisioned for DS3. See
.
•
Check the DS3/EC1 cabling for proper connections.
