The instrument is battery operated, with a large backlit LCD and softkey menu-driven operation. Menu setups can be saved in each of its 8 stores for fast, simple operation on-site and up to 60 days of numeric test results and histograms can be stored in non-volatile memory. The instrument includes an autoconfigure capability so that simple tests can be performed very quickly and with a minimum of training. Battery life is a full working day of up to 10 hours. Instrument Applications EDT-135 E1 Turn-up Availability and performance of an E1 link can be established using either an intrusive or a non-intrusive test. The EDT-135 can be connected via 75 Wor 120 W connectors using Hi-Z termination or at a protected monitor point. A typical simple E1 test will take no longer than 30 seconds, the OK screen quickly indicates when an E1 service is present and error-free. G.826/M.2100 test sequences can then be run, and the results displayed, stored and printed.

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 permit rigorous testing of PDH links but in shorter time periods. Both methods are included as standard software modules in the EDT-135 tester. The following screens illustrate the summary results from G.826 and M.2100 tests. Results Monitor

The Results Monitor screen gives a graphic display of past and present alarm occurrences and error ratios for both near and far ends at the same time. Histograms

n x 64 Timeslot Analysis 64kbit/s timeslots are grouped within the E1 frame to give endcustomers intermediate data speeds such as 128 or 256 kbit/s. The EDT-135 can perform BER analysis on bundles of n x 64kbit/s slots, and drop and insert n x 64 kbit/s to an external protocol analyser via V.11.

A set of histogram screens are displayed, based on the recorded history of alarms, errors and G.826 events. There are histograms for both near and far ends, for each valid alarm, error and G.826 result type (up to 12) at each resolution (days, hours, minutes and seconds). E1 Troubleshooting An extended bit error test will determine whether a periodic fault is causing problems. Electrical equipment such as airconditioning may cause problems at regular times in the day. Error histograms make it possible to identify external events which can be isolated as causes of the problem.

Error histograms can be indicated as a histogram on a scale of up to 60 days.

BIT ERRORS

Faults in an E1 line can be caused by low signal, pulse distortion or jitter. If LOS (loss of signal) or similar alarms are indicated by a network element, Level Measurement and Pulse Shape tests can easily be made to determine where the fault exists in a link, by examining the signal condition. A low or distorted signal received by a network element would indicate a problem with the preceding element or the interconnecting cables. Excessive jitter can result in bit errors, loss of frame synchronisation or similar faults. Where these faults exist, jitter measurements can be performed to determine if jitter is the cause, and also to discover at which point in the system the jitter reaches unacceptable levels. JITTER TRANSFER MEASUREMENT

Jitter Injection

G.703 2Mbit/s Interface

V Interface Troubleshooting (V Status Option) The V Status option shows the status of input and output circuits when testing V.24, V.35 and V.11 interfaces. It also offers ON/OFF softkey control for a selection of the output circuits.

Service Turn-up HCM* Testing (HCM Option) High capacity Multiplexing (HCM) is a Newbridge proprietary rate-adaption and sub-rate multiplexing scheme that provides a bandwidth granularity of 800 bit/s throughout a network. HCM multiplexes multiple V.24 lines into a single G.703 timeslot with very good bandwidth efficiency. The HCM option for the EDT-135 enables users to verify correct configuration, the ability of the link to maintain synchronisation to communicate data without errors.

NE

Various errors can be injected to simulate problems and test the network response. These include bit errors, HCM FAS and Signalling FAS errors, and HCM Frame and Signalling AIS errors. Jitter Measurement

If high jitter levels are isolated to the outputs of particular network elements, these elements can be taken out of service and further tested by injecting jitter at a known level and testing the jitter on the output (jitter transfer). Jitter testing, Level Measurement and Pulse Shape analysis are options which are or will be available for the EDT-135. Primary Multiplexer Testing The 2Mbit/s G.704 framed capability of the EDT-135, and its wide range of interfaces enable in-service and out-of-service testing of a multiplexer to be carried out using a single instrument. Testing is possible in mux and demux directions. For example, testing of the customer-network (mux) direction is performed by transmitting a test pattern into the multiplexer

*HCM is proprietory to Newbridge networks corporation. Used with written permission

Frame Relay Testing (Frame Relay Option) Loaded into the EDT-135, the Frame Relay option provides three test modes suitable for installation and maintenance of Frame Relay services: ! Frame Relay service Turn-Up for verification of user-tonetwork connectivity and configuration ! 'Fox' test for stress testing and Committed Information Rate confirmation ! TCP/IP PING Request Testing, providing additional tests to verify the connectivity of far-end terminals.

V.11 Cable Test Adapter This accessory detects a number of common faults on V.11 cables, which due to the nature of balanced line interfaces would otherwise go unnoticed. ELM-2 Equalizer and Level Monitor The ELM-2 is an accessory to connect the instrument to 2Mbit/s lines carrying hazardous voltages and distortion. It removes DC voltage, equalises the signal and also measures and displays the signal level. PenBERT 2 Mbit/s Monitor The PenBERT PCM monitor can be used with the EDT-135 to perform simple end-to-end tests on a 2Mbit/s line. Errors and alarms are indicated by LEDs.

General Instrument Features Result Storage and Printing The EDT-135 has 8 test memories for the storage of text and histogram results, for view or print 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. 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 framed signals the instrument can determine the framing type, timeslot allocation and test pattern type. Software Option download The testing capability of the EDT-135 can be greatly extended by download of a range of software options. Applicable options include signal Level Measurement, Pulse Shape analysis, Jitter, Large Frequency Offset of transmit clock, Frame Relay, HCM, GSM, enhanced Datacom tests and voice channel Noise Measurement. Programmable timers The instrument can be programmed to start a test at a specified date and time for a selectable duration. Remote Control and Operation The instrument is compatible with the Test Set Manager TSM family which permits remote operation and full remote control for proactive remote fault management and interactive testing. TSM Features The TSM Test Set Manager family of products offer, via an easy to use WindowsTM interface: ! Remote Operation (TSM-10) using on-screen faceplate. ! Full Remote Control (TSM-15) over serial, dial-up modem and TCP/IP links: ! Up to 16 tests running at the same time ! Scheduling for long duration and repeated testing ! Structured testing through test sessions and test objects (x.745) ! SybaseTM standard SQL database for result and configuration storage ! Reporting functions

Equipment Cases A range of equipment cases and shoulder-bags are available to allow convenient transport and storage of the EDT-135 and accessories.
