Installing and maintaining GSM circuits
This powerful tester includes a full set of measurements to install, commission and troubleshoot E1 circuits. Installation tests require basic out-of-service Bit Error Rate (BER) testing to assess cabling integrity. Full commissioning requires extended BER testing to international standards, as well as stress testing and complete assessment of link performance with respect to error and alarm reporting. For successful maintenance, rapid identification of the current line status is critical to the speedy resolution of problems. Specific services (such as GSM) have their own testing requirements, and require a tailored solution to ensure satisfactory operation.
Features such as Autoconfigure and the 'Big OK' result screen make it easy to use with a minimum of training. Quality of Service can be measured with G.821, G.826 or M.2100. Multiplexer tests include MUX/DEMUX and A-D/D-A. Other important features include round trip delay measurement and E1 drop and insert. A comprehensive range of printouts and autoprints can be produced. Histograms with one minute resolution are important for troubleshooting. The DTM-32 family provides a specific driver for simple remote operation. Multiple languages are supported, English, French, German, Spanish, Italian, Portuguese and Turkish.

Battery/Mains Operation
The EST-120/125 have been designed with the user in mind. As well as being lightweight and comfortable to hold and carry, all testers feature large LCD screens with integral backlight for the most demanding testing environments. If you wish to selfsupport the tester, the integral two-position backstand/carry handle can easily be folded out, and can also be configured to suspend the instrument for hands-free viewing.
8-10 hour battery life using rechargeable and exchangeable batteries. Long duration testing can be achieved with a.c. mains power.
Test results are displayed in a concise, graphical format with our recognised 'Big OK' when no errors are present. Multiple language support is standard and comprehensive alarm and error status LEDs give clear indication of problems, even from a distance. And, as you'd expect, all results data can be stored for later analysis or output with a single keypress from the ergonomic keypad.
Software Option Download The testing capability of the EST-120/125 can be greatly extended by downloading of a range of software options. Applicable options include Signal Level Measurement, Pulse Shape Analysis, Jitter, Large Frequency Offset of Transmit Clock, HCM, GSM, and Voice Channel Noise Measurement.
Upgradable for Datacoms Testing The upgrade option enables you to upgrade at any time in the future to a EDT-135. This adds datacom circuit, multiplexer, V.24 modem and Frame Relay test capability.
Autoconfigure The Autoconfigure feature greatly simplifies instrument set-up. A test can be started on framed or unframed traffic using just 2 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 synchronization on a test pattern to be maintained and accurate BER measurement to be made even in the presence of rapid bursts of errors. It also enables differentiation to be made between bit slips and bit errors.
Instrument Applications EST-120/EST-125 E1 Service Turn-up Availability and performance of an E1 link can be established using either an intrusive or a non-intrusive test. The EST-120/125 can be connected via 75W or 120W connectors using Hi-Z termination or at a protected monitor point. A simple E1 test will take no longer than 30 seconds, the OK screen quickly indicates when an E1 service is present and errorfree. G.826/M.2100 test sequences can then be run, and the results displayed, stored and printed.
Result Storage and Printing The EST-120/125 each have 8 test memories for the storage of text and histogram results, for viewing or printing at a later time. Printing of results is supported through the serial port. A set-up screen enables the instrument to be set up for a range of printers.
Programmable Timers The instrument can be programmed to start a test at a specified date and time for a selectable duration.
Remote Operation The instrument is compatible with the DTM-32 remote operation solution.
Timeslot Analysis and Traffic Analysis Access to the timeslots in the E1 frame enables the following tests: -
Voice decode of individual timeslots to establish that the service is running
-
Level and frequency measurements in a selected timeslot to ensure that the multiplexer is operating correctly
-
Drop/Insert to a protocol analyzer for service analysis
histograms for each valid alarm, error and G.826/M.2100 result type (up to 12) at each resolution (days, hours, minutes and seconds).
E1 Service Troubleshooting An extended bit error test will determine whether a periodic fault is causing problems. Electrical equipment such as air-conditioning may cause problems at regular times in the day. Bit errors can be indicated as a histogram on a scale of up to 60 days.
G.826 and M.2100 Analysis G.826 is the ITU-T recommendation for error performance of international digital paths at or above the Primary Rate. The complementary M.21xx series permits rigorous testing of PDH links but in shorter time periods. Both methods are included as standard software modules in the EST testers. The following screens illustrate the summary results from G.826 and M.2100 tests.
Results Monitor
Such displays make it possible to identify external events which can be isolated as causes of the problem. Jitter measurements can be made to determine whether jitter is the cause of excessive bit errors.
A graphical display of past and present alarm occurrences and error ratios for both near and far directions at the same time.
Histograms Faults in an E1 line can be caused by low signal, pulse
