Quick Card
T-BERD 6000Av2 Network Tester
Datacom Bit Error Rate Testing (BERT)
This quick card describes how to configure the T-BERD 6000A as Data Terminal Equipment (DTE) and
run a Bit Error Rate Test on a Datacom interface using typical configuration settings. Please refer to
the MSAM Data Communication and Diphase Testing Manual for an explanation of all settings.
Equipment Requirements:
•T-BERD 6000Av2 equipped with the following:
oBERT software release V26.3 or greater
oTest options:
▪High Speed Datacom test option
(VIAVI Part# CTHSDATA)
•Multi-Services Application Module
(VIAVI Part# C1010V2)
•Datacom Physical Interface Module (PIM)
(VIAVI Part# CPHSDATAV2)
•One of the following Datacom cables to connect the
Datacom PIM to the line under test:
oRS-232/V.24, MIL-188c, EIA-530 Cable
(VIAVI Part# CB-44385)
oRS-449/V.36 Cable (VIAVI Part# CB-44388)
oV.35 Cable (VIAVI Part# CB-44390)
Figure 1: Equipment Requirements
The following information is required to complete the test:
•Interface (RS-232/V.24, MIL-188c, EIA-530, RS-449/V.36, or V.35)
•Signal Mode (Balanced or Unbalanced)
•Timing Mode (Synchronous or Asynchronous)
•Rx Timing Source (Internal, Interface, or Recovered)
•Tx Timing Source (Internal or Interface)
•Out of Band Flow Control (On or Off)
•Test Patterns(s)
•BER Pass/Fail Threshold
Connect to Line Under Test:
•Connect the desired Datacom cable to the Datacom PIM.
•Use the connector labeled “To DCE”to connect to the line under test.

10. Using the drop-down menus, select
“HS Datacom/BERT” for the right results
display.
11. Allow the test to run for desired duration
and verify the following:
•Summary LED is green.
•Pattern Sync LED is green.
•Bit Error Rate result does not exceed
your required threshold. (0.00E+00 if
pass/fail threshold unknown)

12. In the T-BERD’s Quick Config menu,
change “Pattern” to the next value in the
test plan.
13. Press the Restart soft key to reset
results.
14. Allow test to run for desired duration and
verify the following:
•Pattern Sync LED is green.
•Bit Error Rate does not exceed your
required threshold. (0.00E+00 if
pass/fail threshold unknown)

15. Repeat steps 12 through 14 for all Patterns in the test plan. Patterns may include:
•QRSS
•QBF
•R-Trip Delay
