QUICK CARD
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 T-BERD.
•T-BERD/MTS 5800 equipped with the following:
oBERT software release V30.1.0 or greater
oC5E1DS1 test option: E1/DS1 Electrical
oC5DUALPORT test option: Dual Port option
(required on T-BERD 5800-100G only)
•One of the following T1 cable sets to connect the
T-BERD 5800 DS1 Port(s) to the line under test:
oTwo (2) Bantam to Bantam cables (CB-10615)
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

•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. Press the Setup soft key on the top right
side of the screen.
2. Select the indicated folders and configure
your test as follows. Leave all other values at
default, unless specified in the work order.
3. Press the Results soft key to view the
Test Results screen.

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
•T-BERD 5811AND T-BERD 5822 mainframes have both RJ-48C and bantam ports. You may use
Bantam to Bantam, Dual Bantam to RJ-48C, RJ-48C straight through, or RJ-48C crossover cables to
connect the T-BERD to the line under test.
•T-BERD 5882 and T-BERD 5800-100G mainframes have an RJ-48C port. Dual Bantam to RJ-48C,
RJ-48C straight through, or RJ-48C crossover cables may be used.

6. In the T-BERD’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 forAMI
►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)
