Test the Copper, Test the Service, Improve the Process
Equipped with the Copper Testing option, the HST-3000 can quickly
troubleshoot the local loop for line impairments that degrade or impair ISDN BRI
performance. With the HST-3000, technicians can quickly identify and locate
cable impairments, including shorts, grounds, opens, crosses, bridged taps, wet
sections and other high resistive faults. These impairments are easy to assess with
the HST-3000 advanced time domain reflectometer (TDR), precision digital
volt/ohm meter (DVOM) and an accurate resistive fault locator (RFL) to pinpoint
troubles prior to circuit installation. The HST-3000 can also transmit and receive
40kHz wideband tones and with impulse noise, background noise measurements
confirm that noise and loss meet acceptable criteria. Copper test features are
optimized for use anywhere on the local loop—at the NID, crossbox, pedestal,
main distribution frame or anywhere a technician might gain access to the local
loop to locate the source of trouble.
After the physical layer has been tested, the actual ISDN service can be tested by
placing and receiving calls verifying proper switch translations. The 2-wire facility
that carries the ISDN BRI service can be qualified by performing BER analysis
with a number of patterns, such as 63, 511 and 2047.
Pre-programmed tests and customized scripts ensure that all technicians, inclu-
ding novice users, follow the same procedures, eliminating mistakes caused by
improper test configurations or incorrect procedures.
JDSU’s TechComplete
TM
software (optional customized) allows the HST-3000 to
improve turn-up and maintenance processes. This is done by operating with service
provider’s dispatch and closeout report systems to offload stored test results for later
trend analysis and coaching reports. With these features, the HST-3000 can reduce
repeat rates and failures and improve overall process efficiency.
Flexible and Rugged Design
The HST-3000 incorporates a rugged, weather-resistant design and long battery life
that are ideally suited for use in the field. Its modularity allows for field upgrades to
support new testing requirements. Standard Ethernet, USB, and serial connections
offer flexibility to easily download software and offload captured test data.
Easily configurable, the HST-3000 can be used by different technicians with different
responsibilities to perform a wide number of tests. The HST-3000 is easily upgradeable
with technologies and advanced options that support the changing needs of service
installers.
