TDR Measurement Option
This option locates copper faults. The
T-BERD Outside PlantTester can be easily
configured for TDR measurement by
selecting the cable type and approxi-
mate cable length being used. By
completing these simple steps, the
cumbersome process of determining
complex constants such as pulse width
and pulse height is avoided. Once the
TDR is set up, the graphical display
on the mainframe front panel allows the
user to immediately view the TDR traces.
A built-in zoom feature facilitates fault
identification by focusing on copper
faults such as bridged taps, splits, load
coils, high-resistance opens, and bad
splices.Faultidentificationisperformed
at the push of a button, with the distance
to the fault displayed in feet.
Turn Up and Troubleshoot
FT1/T1 Circuits
The T-BERD Outside Plant Tester
mainframe features a full-span T1
transmitter and receiver used to
identify marginal troubles with all
standard T1 stress patterns at various
output levels. Automatic configuration
and results with summary functions
immediately identify the presence of
T1 pulses, pattern, framing, and error
status. Additionally, the mainframe
can qualify T1 spans with automated
MULTIPAT ™ and BRIDGTAP ™ stress
patterns. To stress the entire T1 span
and verify the error tolerance of
network equipment, the T-BERD
Outside Plant Tester can insert bit
errors and BPVs.
Fractional T1 (FT1) Option
This option enables the T-BERD
Outside Plant Tester to perform BER tests
on selected channels in order to verify
transmission on contiguous and non-
contiguous FT1 bandwidth. It also
allows the technician to verify VF
circuit performance with 404, 1004,
2804, and 2713 Hz tones at various
output levels.
Standard T1/FT1 BER testing provides
the most accurate measure of point-
to-point transmission performance
by stress-testing the circuits to
ensure proper circuit configuration.
The advanced software options that
complement T1/FT1 BER testing
include: Advanced Stress Patterns
Option, Channel Monitor Option,
Enhanced ESF Option and Smart
Loopback/Command Codes Option.
Advanced Stress Patterns Option
This option enables the technician to
stress repeatered T1/FT1 circuits with
a variety of stress patterns such as
55 octet, T1-DALY, and other long user
patterns as recommended by the
ANSI T1.403 standard.
Channel Monitor Option
With this option, the T-BERD Outside
Plant Tester is able to simultaneously
monitor ABCD bits of all 24 timeslots,
listen to voice quality, and view the
data bits of individual DS0 channels.
Enhanced ESF Option
This option adds testing flexibility
to the T-BERD Outside Plant Tester.
It enables the T-BERD Outside Plant
Tester to decode ESF one-second
broadcastperformance reportmessages
(PRMs) to verify remote in-service
circuit performance. With this option,
the T-BERD Outside Plant Tester can
also emulate ANSI T1.403-compatible
CSU equipment to verify proper opera-
tion during circuit installation and fault
isolation as well as query performance
monitoring NIU equipment to retrieve
in-service performance data to verify
remote circuit operation. This option
supports Westell ™ equipment.
