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.

4. Using the Select Test menu, Quick Launch

menu, or Job Manager, launch the

DS1/DS3►DS1►DS1 BERT►Terminate

test.

•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.

CREATE REPORT

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)
