Acterna E1 and Data Testers
(EST-120, EST-125, EDT-130, EDT-135)
Scalable testing for digital networks
The range of E1 and Data Testers
provide a scalable, future-proof
solution for the testing needs of
engineers involved in the installation,
commissioning and maintenance of
digital networks. These instruments
can carry out both framed and unframed
tests on a wide variety of equipment,
ensuring that technicianscan perform
their jobs quickly and efficiently. The
E1 and Data testerscome in compact,
robust, handheld packages thatmake
them ideal for field use.
This low cost, time saving, multiple
language solution for E1 and Data
testing supportsa wide range of
software options including Pulse
Shape Analysis, Jitter, and Frame
Relay allimplemented on the same
straightforward user interface. The
generic hardware platform can be
configured and optioned to meet
the needsofvarious engineering
groups or activities. It can also be
reconfigured or upgraded as required.
Highlights
– Provides a scalable test solution for
E1 and Data testing applications,
supported bya large range of
software options for E1 services
(Frame Relay, GSM) and subrate
multiplexing system (X.50, HCM,
V.110) testing
– Allows for rapid evaluation of
circuits through an intuitive user
interface with an autoconfigure
feature and large, clear
results screens
– Employs a full set of physical
layer tests for E1 balanced and
unbalanced circuits including
BERT, VF, Round Trip Delay,
Signal Level, Pulse Shape and Jitter
– Provides standard options for
Quality ofService (QoS) measurements to ITU-T G.821, G.826,
and M.2100 recommendations
– Makes clear distinctions between
bit errors and bit slips in QoS
testing through the patented
Gelbrichtsynchronization method
The range of products comprizes
EST-120, EST-125, EDT-130, and
EDT-135. The EST-120 and EST-125
are multipurpose field service testers
designed for commissioning,
maintenance, and troubleshooting
on E1PCM circuits. Theycan perform a
wide variety of tests, including: framed
and unframed monitoring, framed
and unframed end-to-end testing,
drop and insert, channel associated
signaling monitoring, Round Trip Delay
measurement and repeated BERT.
The EDT-130 and EDT-135 have a
similar range of features for E1 circuit
testing, plusan extended range of
interfaces for data circuitand primary
multiplexer testing.
Some ofthe key functionsand benefits
of the E1 and Data testers include:
Ease of use
The EST/EDT range hasbeen designed
with the technician in mind. The instruments are lightweight, easy to hold and
carry, and feature a large LCD screen
with integral backlightfor the most
demanding testing environments.
Rapid faultidentification
Testresultsare displayed in a concise,
graphical formatwith our recognized
big “OK” when no errors or alarms
are present(figure 1). The testers
also supportmultiple languages.
With comprehensive alarm and errors
status LEDs, technicians are given a
clear indication of problems even at a
distance. All resultsand data can be
stored forlater analysis and printed to
an external printer or computer with a
single key press.
Autoconfigure
The autoconfigure feature greatly
simplifies instrument setup. A test
can be started on framed or unframed
traffic using just two key presses. For
a framed signal the instrument can
determine the framing type, timeslot
allocation and test pattern type.

Gelbrich synchronization
The patented Gelbrich synchronization
method enables test pattern
synchronization and accurate BERT
measurement even in the presence
of rapid bursts of errors. Italso differentiates between bitslips and bit errors,
important in QoS testing.
Resultsstorage and printing
The EST/EDT range ofinstrumentshas
eight configuration and test memories
that store test configurationsand
results, allowing them to be viewed or
printed ata later time. Results are
printed through the serialportand a
setup screen enables the instrument
to be set for a range of serialprinters.
Parallel printersare supported with
the use of a serial to parallel converter
cable. Alternatively, printing to a PC
can be achieved using a software
program such as WG Print Capture.
Programmable timers
The instrument can be programmed to
start a delayed testata specific date
and time for a selectable duration.
Battery/mains operation
For field use, the instrumenthas an
8-10 hour battery life using rechargeable and exchangeable batteries.
Long duration testing can be achieved
using the combined ACmains power
supply and charger.
Software options
A key feature of the EST-125 and
EDT-135 instruments isthe ability
to load software optionsto extend
testing functionality.
Application orientated packages
A range of application orientated
packagesisavailable that combines
the instruments with a carefully
selected collection of software options
and accessories. Should requirements
change, a range of packagesis
available for upgrading EST/EDT
instruments to EDT-135.
Accessories
The ELM-2 accessory allows the
instrument to be connected to 2 Mbps
lines carrying hazardous voltages
and
√f distortion. Itremoves the DC
voltage, equalizes the voltage signal
and also measures and displays the
signal level.
The V.11 cable testadapter is used
to detecta number ofcommon faults
on V.11 cablesthatmightotherwise
go unnoticed due to the nature of
balanced line interfaces.
