T1 Bit Error Rate Testing (BERT)
This quick card describes how to configure and run a T1 Bit Error Rate Test to a hard loop,
or another similarly configured VIAVI Test Instrument.
•OneAdvisor 1000 equipped with the following:
o100G Transport Module
oBERT software release V30.1.0 or greater
oC5E1DS1 test option: E1/DS1 Electrical
oC5DUALPORT test option
•One of the following T1 cable sets to connect the
100G Transport Module DS1 Port(s) to the line under test:
oDual Bantam to RJ-48C cable (CB-41645)
oRJ-48C Patch cable (Straight-through or cross-over
depending upon equipment under test) Figure 1: Equipment Requirements
LAUNCH TEST
1. Press the Power button to turn on the
OneAdvisor.
2. Press the 100G Module Test icon
at the top of the screen.
3. Tap the Power button and click
to launch the 100G Module.

•The following Information is needed to
configure the test:
•T1 Line Code (B8ZS or AMI)
•T1 Framing (ESF or D4)
•Clock Source (Internal or Recovered)
•Test Patterns(s)
•BER Pass/Fail Threshold
1. Tap to open the Tools Panel and
select .
2. Press to continue.
3. Press the Setup soft key on the top right
side of the screen.
4. Select the indicated folders and configure
your test as follows. Leave all other values at
default, unless specified in the work order.
5. Press the Results soft key to view the

RUN TEST
1. Using drop-down menus , select
“Interface/Signal” for the right results display.
2. Press the Restart soft key .
3. Verify the following:
►Summary LED is green.
►Signal Present LED is green.
If the LED is red, check your cables.
Tx and Rx may be reversed.
►Frame Sync LED is green.
►RX Frequency (Hz) = 1544000 +/- 50 Hz.
4. Using drop-down menus , select
“Payload/BERT” for the right results display.
5. Allow the test to run for desired duration and
verify the following:
►Pattern Sync LED is green.
►Bit/TSE Error Rate result does not
exceed your required threshold.
(0.00E+00 if pass/fail threshold unknown)

CONNECT TO LINE UNDER TEST
•The OneAdvisor 100G Transport Module has an RJ-48C port. RJ-48C to Dual Bantam, RJ-48C
straight through, or RJ-48C crossover cables may be used to connect to the line under test.

6. In the OneAdvisor’s Quick Config menu,
change “Pattern” to the next value in the test
plan.
7. Press the Restart soft key to reset results.
8. Allow test to run for desired duration and verify
the following:
►Pattern Sync LED is green.
►Bit/TSE Error Rate does not exceed
your required threshold.
(0.00E+00 if pass/fail threshold unknown)
9. Repeat steps 6 through 8 for all Patterns in the
test plan. Patterns may include:
►QRSS: Simulates live T1 traffic
►All Zeros: Tests for equipment
mis-optioned for AMI
►Multipat: Five commonly used test patterns
to allow BER testing without having to select
each test pattern individually. Patterns are:
All Ones, 1:7, 2 in 8, 3 in 24, and QRSS.
Results are shown in the “DS1/Multipat”
results display.
►Delay: Measures Round Trip Delay (RTD)
instead of Bit Errors (RTD values are shown
instead of BER in the “Payload/BERT” results
display)
