Applications
The T-BERD Outside PlantTester can
verify physical layer functionality by
performing standard BER testing.
In addition, it performs DC measure-
ments to accurately identify copper
faults. The TDR’s graphical display
allows the technician to view the
respective faults and confirm the
location, aswell as the type of fault.
Along with BER testing, the T-BERD
Outside PlantTester can use intelligent
repeater technology to sectionalize
span problems, while the prepro-
grammed loop codesenable the user
to loopbackvarious equipment on
the span. When equipped with the
HDSL/ISDN/DDS Measurement
Option, the T-BERD Outside Plant
Tester is able to perform lossmeasure-
ments at various frequencies to assure
proper signal levelon the span for
HDSL, ISDN, BRI, and DDS circuits.
Test copper loops
In order to verify that the copper loop is
able to support digital service such as a
T1, the copper facility has to be tested.
To effectively test the loop, technicians
need a digitalvolt ohmmeter (DVOM)
and TDR to determine the physical
impairments and measure the distance
to the fault. The T-BERD Outside Plant
Tester’s DC Measurement Option,
along with the TDR Option, allow the
technician to effectively prequalify the
copper loop.
DCMeasurement Option
This option enables the T-BERD
Outside PlantTester to perform ohm,
amp, and, voltage measurements:
– ‘Ohm measurements’allow the
technician to quickly identify physical
impairments, such as opens, shorts,
grounds, and one-side faults with
automated resistance measurements
between tip, ring, and ground
– ‘Amp measurements’ immediately
detect one-side faults, such as opens
and grounds, with an automated
current measurement between tip
and ring; Automated voltage measure-
ments help isolate bad repeaters and
span-powering problems
A complete solution, the T-BERD
Outside PlantTester provides:
– One tool, multiple tasks
Cost savings through consolidation
of multiple test capabilities and
features (copper analysis, FT1/T1,
HDSL, DDS, ISDN, span sectional-
ization) into a single testset
– Investmentprotection
Customers can build a custom test
set for their testing needs with an
option of field-upgrading their unit
later with additionalfeaturesat a
fraction of the cost of buying a
new test set
– Fast implementation
A variety of accessories and features
with a common menu interface
reduces training time for technicians
and leads to quicker turn-ups and
closures of trouble tickets
– Reliability
T-BERD’s long-running reputation
for designing reliable test equipment
means customerscan be assured
that their test setwill not incur
unnecessary repair costs
