Acterna ANT-10G
Advanced Network Tester – SDH version
Powerful tester for SDH networks
Over the last few years, there hasbeen a dramatic increase in global com­munications services. The Internet continues to be an area of rapid growth. As a response to the increasing demand for bandwidth, two different technologies have simultaneously developed. One is the time-division multiplexing (TDM) of synchronous channels to achieve higher bitrates. The other is dense wavelength division multiplexing (DWDM), which is the optical multiplexing of a large number of synchronous systems, allof which are then carried by a single fiber. The goal of each technologyis the same, however – to make the best possible use of available fiber capacity.
So whether it’s TDM or DWDM, Acterna partners with systems manufacturers and network operators to define new standards of quality and technical excellence while guaranteeing maximum ease of use for testers and technicians. The result isthe Acterna Advanced NetworkTester ANT-10G – SDH version.

Automatic modes
Autoconfiguration
The Autoconfiguration routine auto­matically sets the ANT-10G to the input signal. ANT-10G searches at the electrical and optical interfacesfor the presence of standard PDH and STM-N signals (G.703, G.707, O.151, O.181) and the payload contents in channel 1.
Automatic SCAN function
The SCAN function permits sequential testing of all C11 or C12 channels via AU-3 or AU-4 in a SDH signal. The ANT-10G receiver checks for alarms in the receive signal, the SDH structure and all channels, and for synchronization of the selected test pattern in all channels. The results (OK/not OK) for each channelare entered in a matrix. The generator runs simultaneously and can be used to stimulate the device under test.
Automatic TROUBLE SCAN function (figure 3)
The TROUBLE SCAN function permits sequential testing of all C11 or C12 channels via AU-3 or AU-4 in a SDH signal. The ANT-10G receiver checks for alarms in the receive signal, the SDH structure and all channels. The results (OK/not OK) for each channelare entered in a matrix.
A detailed alarm history can be displayed by selecting a channelfrom the matrix.
The alarm status of individual channels can be displayed following the measurement. Only the receive channels are altered during a TROUBLE SCAN.
AutoScan function (figure 4)
This automatic AutoScan function enables you to rapidly check the signal structure, the mapping used and the payload – even with mixed mapped signals. The ANT-10G receiver analyzes the incoming received signal and provides a clear overview of all the signals present in the composite receive signal.
The variable scan depth setting enables even complex signalstruc­tures to be resolved and displayed clearly. Even Trace Identifiers are evaluated. All the displayed results can be printed out.
Automatic SEARCH function
Channel shifts in the payload may occur when measuring complex network elements, depending on the configuration of the device under test. The SEARCH function permits rapid automatic location of the test channel (C11 or C12 with defined PRBS) in the payload of a SDH signal. The ANT-10G receiver checksfor alarms in the receive signal, the SDH structure and all channels, and for synchronization of the selected test pattern in all channels. The results (OK/not OK) for each channel are entered in a matrix. An OK result indicates that the corre­sponding channel containsthe signal searched for. Only the receive channels are altered during a SEARCH.

Clock frequency measurement
The deviation of the input signal clock frequency from the nominal frequency is displayed in ppm.
Delay measurement
A delay measurement is used to line-up satellite hops, to test the maximum permitted latency in storage exchanges and cross-connect systems and to check the loop circuits of regenerators. The ANT-10G measures the time taken for the test pattern to be transmitted from the generator back to the receiver via the path under test. The measurement is made on the test patterns in the selected channel, in the containers (bulk or PDH) for SDH or in the selected channel at the lowest hierarchy level of PDH multiplex systems. To avoid ambiguities in the measurement, two measurement times are provided. Measurement range Bit rates from 8 to 155 Mbps 1 ms to 1 s Bit rate 2 Mbps 10 ms to 5 s Bit rate 64 kbps 100 ms to 16 s

Ring testing – APS time measurement (figure 7)
In synchronous networks, a defined maximum switch-over time is necessary for the traffic in case of a fault. To verify compliance with this requirement, the ANT-10G measures the switch-over time with 1 ms resolution. The result can be printed. Criteria for the time measurement TU-AIS, MS-AIS, AU-AIS, bit error Max. measurable switch-over time 2 s Resolution 1 ms Allowable error rate for user signal <2 x 10
Ring testing – Byte capture SOH and POH
To analyze the SOH/POH functions, individual bytes vs. time needs to be captured, allowing detection of errors or short-term changes with frame level precision. The capture function is started by a selectable trigger. Values for a selected byte are stored and can be accessed subsequently in a table of values. Particularly in capturing the APS sequences, the bytes (K1, K2) are displayed as an abbreviation of the standard commands. The function also allows recording of the N1 or N2 bytes for evaluation of “Tandem Connection” information. H4 sequences can also be analyzed very easily. The results can be printed or exported.

TCM is a method used to monitor the performance of an SDH path subsection path via the N1/N2 bytes. This is particularly useful when the path is routed via different network providers. If errors occur on an end-to-end connection, you can use TCM to determine which subnetwork the errors occurred in. The ANT-10G helps to monitor the content of the N1/N2 bytes and provides users with easy interpretation of the detailed events. Capture TCM frames all N1/N2 bytes, TC-IEC, TC-AIS, TC-REI, TC-OEI Trigger events Start of TCM frame (TCM FAS word) Storage depth 266 bytes (3.5 TCM frames) On-line monitoring of alarms and trace identifier.

TC-RDI, TC-ODI, TC-REI, TC-OEI On-line display of TCM access point identifier TCM error measurement Error types TC-IEC, TC-DIFF, TC-REI, TC-OEI
TCM Byte Sequencer and Editor
This serves to test a sequential TCM process (tandem connection monitoring) in the N1/N2 bytes. A sequence of 76 bytes simulating a TCM frame (equivalent frame) is generated. Individual values can be edited as binary or hexadecimal values to simulate various events for TCM evaluations. Additionally, major events may be simulated, line alarm, errors and trace identifier.

Phase hits
The instrument detects when the programmable threshold for positive and negative jitter values is exceeded. The result indicates how often this threshold was exceeded. Setting range for positive and negative thresholds (depending on measurement range) 0.1 up to the half measurement range.
Jitter versus time (figure 11)
This function is used to record variations of jitter with time. It allows the positive and negative peak values or peak-to-peak values to be displayed versus time. Measured values have one second resolution. Measurement duration is up to 99 days. By simultaneously evaluating alarms and errors, corellations between events can be quickly identified.
Clock jitter measurement
The ANT-10G can also measure the jitter on the clock signals (square-wave) at standard bit rates. All built-in bit rates with electrical interfaces up to 155 Mbps can be measured (requires option BN 3060/91.30 or 3060/91.31).
RMS measurement
T1.105.03, GR-253, GR-499, G.958 (or G.783 rev.) The RMS value is measured on-line and displayed in UI. The peak jitter and RMS values can be displayed simultaneously; a graph versus time is available for long-term analysis. An RMS filter preset is available.
Wander analysis
Time interval error (TIE)
To Ο.172 numerical and graphical Sampling rates please see under Ο.172 wander analyzer MTIE is additionally determined as a continually updated numerical value. To prevent data loss or premature termination of long term measurements, the ANT-10G checks the remaining space on the hard disk before the start of the measurement. If necessary, the selected measurement time can be adjusted. The TIE values are recorded and are then available for subsequent offline MTIE/TDEV evaluations. The values are also saved in .csv format for documentation or further analysis.

MTIE/TDEV Off-line analysis evaluation
This software provides extended off-line statistical analysis facilities for the results of wander measurements. TIE values results obtained using the ANT-10G are analyzed according to ANSI T1.101, Telcordia GR-1244, ETSI ETS 300 462, EN 302 084, ITU-T Ο.172, G.810 to G.813. Network synchronization quality is presented graphically using the MTIE (maximum time interval error) and TDEV (time deviation) parameters. To ensure correct assessment, the tolerance masks for PRC (primary reference clock), SSU (synchronization supply unit), SEC (synchronous equipment clock) or PDH can be superimposed. The results and masks can be printed out with additional user-defined comments. This software allows several TIE results to be displayed simultaneously. Decisive details during long term measurements disappear in the multitude of results. An effective zoom function is availablefor detailed wander characteristic analysis.
Result printout and export
The results can be printed out and stored internally or on floppy disk. The file format allows further processing using standard PC software.
Frequency offset and frequency drift rate (ANSI T1.101)
To ensure reliable operation when a clock source is in holdover mode, the frequency characteristics must not exceed specific deviation limits relative to an absolute reference source. To verify this data, the ANT-10G determines the following over the selected measurement interval: Frequency offset in ppm Frequency drift rate in ppm/s
Automatic measurements
The following automatic measurements can be run for all standard bit rates and interfaces included in the mainframe configuration (electrical/optical) up to 10 Gbps.
Automatic determination of selective jitter transfer function, JTF
Telcordia GR-499, GR-253, ANSI T1.105.03, ITU-T G.958. The jitter transfer function indicates the ratio of the jitter amplitude at the output of the device under test to that at the input at various frequencies. This determines whether the device under test reduces or amplifies input jitter and at which frequencies. After a calibration measurement to minimize intrinsic errors, the ANT-10G outputs a preselected jitter amplitude at various frequencies and measures selectively the jitter amplitude at the output of the device under test. The ratio of the amplitudes in dB is the jitter transfer function. The preselected amplitudes correspond to the mask for maximum permitted input jitter. The jitter frequencies and amplitudes can also be edited. Calibration values can be saved and used again for other measurements.
Additional measurement mode
Transfer MTJ results:
An MTJ measurement is first performed. The measured amplitude values can then be used automatically as generator values for the JTF measurement.
The results can be displayed in tabular and graphical form.
The graphical display includes the standard tolerance masks specified in T1.105.03 and GR-253 or G.735 to G.739, G.751, G.758. The distance of the measurement points from the tolerance masks indicates the degree to which the device under test meets the requirements of the standard.
Tolerance mask violations during the measurement are indicated in the numerical table.
Freely programmable tolerance masks
The existing tolerance masks for the ANT-10G can be altered as required to suit requirements that do not conformto specific standards. The new valuesselected for jitter frequency and jitter gain/loss are stored when the application is saved.
figure 13 Display of MTIE/TDEV resultsand comparison against masks
MRTIE – relative MTIE (G.823 and EN 302 084)
If the reference is unavailable (too far away) when analyzing the wander of asynchronous signals, the MTIE analysis may have a superimposed frequency offset. This offset depends on the difference between the signal and local reference clocks. The MRTIE measurement subtracts the frequency offset from the result so that the “actual” wander characteristic is shown. Accessory for wander analysis Standard frequency source please see end of section.

The result of each measurement is shown in a table as the status message “OK” or “FAILED”.
Automatic pointer sequences for analyzing combined jitter
(available with CATS test sequencer option) Among other things, T1.105.03 defines various pointer sequence scenarios for testing combined jitter (mapping and pointer jitter) at network elements. These sequences are normally selected manually and the jitter measured. ANT-10G allows simple automation of these sequences. The entire sequence is started and the maximum pointer jitter determined with a single key press. This saves considerable time spent in setting up the test and executing the measurement.

ATM options
With its ATM options, the ANT-10G enables commissioning tests on newly installed ATM links. The major error and delay related performance parameters can be quickly and reliably verified in this manner. Using the flexible cell generator, policing functions can be easily checked. Bit error analyses and alarm flow diagnostics allow a fast assessment of whether links are working properly.
ATM cells can be generated for all bit ratesup to STM-4c/ OC-12c.
ATM Basic BN 3060/90.50 General
Adjustable test channel from 0 to 150 Mbps
In ATM networkelements, user channels are monitored with the UPC (usage parameter control). The sensors of the control instance can be quickly checked ifthe bandwidth of a test channel exceedsthe set threshold in the network element. For all measurements, the test channel in the ANT-10G is set on-line. Settings are made directly with a control(figure 18) which shows the bandwidth in Mbps, Cells/s or percent. This makes it easyto simulate CBR (constant bit rate) sources. For each interface, the load setting has a range from 0.01 percent to 100 percent. Thiscorresponds to the load conditions which can occur in the real world.
Load profiles
A test channel can be generated with typical load profiles in order to stress network elements or simulate source profiles. In burst mode, for example, the burst load, burst length and burst period parameters can be used to simulate a video signal whose key figures correspond to a real-life signal.
Background load generator
To make a real-time measurement under loaded conditions, additional background load can be simulated to supplement the test channel (foreground traffic). The ATM channels are defined using an editor. The user specifies the repetition rate of the load cell and a sequence ofempty cells. Load channels can be transmitted continuously as a sequence. The load generator can also be used separately with the test channel switched off. In this case, the channels and profiles can be user-specified.
Determining cell delay variation
The ANT-10G includes very powerful tools for measuring delay parameters. Once a precise measurementhas been made, subsequent measurements usuallyrequire only a low-resolution display to enable rapid pass/failassessment. Delay values are displayed bythe ATM Traffic analyzer as a histogram with a minimum class width equal to 160 ns (maximum 335 ms). As a result, delay fluctuations are shown graphically with the same resolution. An adjustable offset can be used to maintain measurement accuracy even if the delay values are high, for example over internationallinks.
F4/F5 OAM alarm flow
In accordance with I.610 and the ATM forum standard, the status of ATM paths and channels ist ransmitted in the OAM cell stream (fault management). The ANT-10G generatesthe alarms VP-AIS, VC-AIS or VP-RDI, VC-RDIfor the foreground channel. The receiver simultaneously detects alarms and error messages in the channeland path.

Selection of ready-to-run applicationsand graphics-supported testsettings
The graphical method for making test settings isunique. The way that the ANT-10G is connected to the device under test, ensures that the protocol layers and settingsincluded in the test, or the ATM servicesto be tested can be quickly and easily seen. Users can select from a range of predefined test setups or customize their own. Predefined ATM channels can be selected from a database or new channels added. Additionally, all characteristics and parameters for each channel are also stored, for example: traffic type, circuittype, header, traffic contract, trafficsource. An editor program is provided for defining the test circuits.
Direct testing of all contract parameters
Some of themain tasks facingmeasurement services are determining whether users are keeping to traffic contracts and how they are doing so, and establishing how the network handles such contracts. These questions can only be answered by means of a test thatenables all the major service parameters to be set and measured.
For such applications, the Broadband module includes an editor that permits all the contractparameters for the various ATM servicesto be set for the first time. For terminal emula­tion, all contract characteristics and of the trafficmodel used for the test can be defined with the Channel Editor.
After starting the measurement, the ANT-10G generates test traffic using the selected parameters. Thisa llowsdirect demonstration of the way that the ATM network handles the user traffic and whether the agreed network resourceswere in fact available.
The source parameters can be varied on-line during the measurement. This makes it possible to detect policing errors or incorrect network access threshold settings quickly and easily.

ATM QoS testwith four different SVCs
The ANT-10G with BAG can perform SVC and PVC tests on up to four circuits simultaneously. Multi-channel services, suchas those used for multimedia applications, can thus be simulated.
Any channel type can be selected from the database or newly defined for each channel.
Realtime measurements conform to the ITU-T O.191 standard which defines the test cellformat and the test algorithm. Important source parameters can be regulated online during the test. The results are clearly displayed, with graphics elements used to indicate defectsor highlight status information.
Signaling analysis
Sequence errors in the signaling protocol adverselyaffect correct management ofATM services. They can be detected by recording and displaying all channel states and changes of state in chronological order with timestamp information. The ANT-10G constantly monitorsthe states of the SVCs being tested. The protocol can thus be checked for correct­ness and any errors detected rapidly. The connection set up time is measured for all test channels.
figure 22 ATM testresults for a realtime measurementon channel A
Trafficmanagement and contract optimization
Traffic shaping (single/dualleaky bucket) can be switched on for each ATM channel, even on-line during the measurement. In addition, the following are displayed per channelwith soft LEDs:
Non conforming ce lls(NCC)Dropped cells (DC)
Using this information it is possible to checkwhether the UPC (usage parameter control) functions ofthe network are work­ing and are implemented in compliance with the standard. At the same time, the degree of utilization of the trafficcon­tracts can be determined. Using the facilitiesfor simulating all relevant source parameterswith up to four competing channels, it is possible to optimize the contract parameters in the network.M

Professional record of results
The ANT-10G generates a professionalrecord of instrument settings and test results that can be output from a standard printer. The record can be used for various purposes, for example:
Guarantee documentationAcceptance documentationInstallation recordEvidence of adherence to contract, and so on.
In other words, the ANT-10G handles the entire processfrom measurement through to producing a permanent record of the results

Simplified test automation (figure 24) Computer aided test sequencer (CATS) and test case library
The test sequencer is the ideal tool for rapid, simple adaptation and automatic performance of complete test sequences on the ANT-10G (CATS = computer aided test sequence). This saves time where repetitive tests are required in the production, installation and monitoring of SDH, SONET and ATM network elements. The comprehensive test case library includes solutions for various applications, such as BERTs, alarm sensor tests, jitter, offset and pointer tests and monitoring ATM Quality of Service (QoS) parameters.
Once created, test sequences are started with a single mouse click. A report in ASCIIformat for documentation purposes is compiled during the measurement. All test cases are predefined and ready to run. They can also be easily customized.
More information is found in the data sheet “Test Automation and Remote Control”.
