LAUNCH TEST
1. Press the Power button to turn on the
T-BERD.
2. Press the Test icon at the top of the
screen to display the Launch Screen.
3. Using the Select Test menu, Quick Launch
menu, or Job Manager, launch the Ethernet
Layer 2 Traffic test on Port 1 for the desired
data rate. For example:
Ethernet ►1GigE Optical ►Layer 2 Traffic
►P1 Terminate.
4. Tap to open the Tools Panel and
select .
5. Press to continue.

►The followingInformation is needed to
configure the test:
•Physical Interface (10/100/1000BASE-T,
1000BASE-LX, 10GBASE-LR, 100GBASE-LR4,
etc.)
•Auto Negotiation settings of the port
under test.
►For Optical Interfaces:
1. Press the Setup soft key on the
top right side of the screen.
2. Select the Interface/Connector folder.
3. Insert desired Optical Transceiver into
the Port 1 SFP or QSFP slot on the top
of the T-BERD.
4. Review SFP information in the
Connector tab:
oVerify that the SFP operates on the
required wavelength
(850nm, 1310nm or 1550nm).
oVerify that the SFP supports the
required data rate (1G, 10G LAN,
etc).
oNote the Min and Max Tx Levels
(dBm) and Max Rx Level (dBm) to
assess if optical attenuators are
required.
oPress the Results soft key to
return to the Test Results screen.
►For 10/100/1000 Electrical and 1GigE
Optical tests, tap the Ethernet tab of the
Quick Configuration menu and set
Auto Neg. to the same value as the Ethernet
port under test (On or Off).

►For Optical Interfaces:
1. Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (SFP, attenuators,
patch cables, bulkheads)
oFocus the fiber on the screen.
oIf it appears dirty, clean the fiber end-face
and re-inspect.
oIf it appears clean, run the inspection test.
oIf it fails, clean the fiber and re-run
inspection test. Repeat until it passes.
2. If necessary, insert optical attenuators into
the SFP TX and/or RX ports.
3. Connect the SFP to the port under test
using a jumper cable compatible with the
line under test.
4. Select the Laser tab in the Actions panel.
5. Press . The button will turn yellow
and be relabeled .
6. Press the Restart soft key .
7. Verify the following:
oSummary LED is yellow.
oSignal Present LED is green.
oSync Acquired LED is green.
oLink Active LED is green.
►For Copper 10/100/1000BASE-T interfaces:
1. Connect the 10/100/1000 RJ-45 jack to
the port under test using CAT 5E or better
cable.
2. Press the Restart soft key .
3. Verify the following:
oSummary LED is yellow.
oSync Acquired LED is green.
oLink Active LED is green.

LOOP UP
The T-BERD may be looped up by any of the
followingmethods. Once looped, the T-BERD will
reflect all received test packet after inverting
Source and Destination MAC addresses.
1. Broadcast Loop up message: The T-BERD
will respond to VIAVI Loop up messages
received via Broadcast MAC address and enter
Local Loopback (LLB) mode.
2. Unicast Loop up message:
►The T-BERD will respond to VIAVI Loop
up messages received via Unicast MAC
address and enter LLB mode.
3. Manual Local Loopback:
►Select the Actions Panel and tap
to manually enter LLB mode.
►Tap again to exit LLB mode
when the test is complete.
With Unicast and Manual loopback, the operator
of T-BERD traffic generator will need to know the
MAC address of this T-BERD:
►Tap the Setup soft key , select the
Ethernet menu, and tap
to displaythe Factory Default Source
MAC Address of your T-BERD.
►Provide this address to the operator of the
T-BERD Traffic Generator, upon request.
►Press the Results soft key to view
the progress of the test.
