Connect a cable from the DS1 test set
receive
connection to the OUT jack of the DSX-1
associated with the DS1 tributary to be tested (start with the first).
Result:
The DS1 test set should indicate it is receiving an error free QRSS signal with
B8ZS formatting.
If an error free signal is not received:
•
Verify that the DS1 line coding format is set to B8ZS using the
View -> Equipment
command
•
Verify that the LBOs are set according to cable length using the
View -> Equipment
.
•
Check DS1 cabling for proper connections.

DS1 non-terminating equipment transmission testing (LNW80 switch or LNW59 without optics)
Perform this test when the 1665 DMX is equipped with LNW80 switch packs or LNW59
without optics in the main slots.
Facility loopback testing allows the installer to verify the electrical cabling to the 1665
DMX NE. Follow the procedure below to perform a facility loopback test at the 1665
DMX shelf.
To test cabling to the DSX-1, use a DS1 test set to transmit and receive toward the facility
loopback.
Perform the following tests for each DS1 circuit cabled to the 1665 DMX.
