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

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.

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.

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 measurementTU-AIS, MS-AIS, AU-AIS, bit error
Max. measurable switch-over time 2 s
Resolution1 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.

Tandem connection monitoring (TCM) (figure 8)
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.

Jitter and wander options
As an alternative to the STM-16/OC-48 option, jitter applications up to 622 Mbps
or wander at 10 Gbit are possible with the ANT-10G. The modules are optimized
for compliance with the latest standard (Ο.172) and assure reliable jitter and
wander measurements, useful when analyzing pointer jitter in 10 Gbps systems,
for example. ANT-10G is particularly adept at wander analysis. The graphical
MTIE wander analyses require no external computing resources and allow rapid
verification of the synchronicity of a SDH network. Jitter/wander components are

The ANT-10G retains phase synchronicity even when pointer jitter occurs (phase
tolerance to Ο.172).

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

Sampling ratesplease 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 offsetin ppm
Frequency drift ratein 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.

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 BasicBN 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.

figure 21 Channel Editor: setting the trafficdescriptor
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.

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 documentation
– Acceptance documentation
– Installation record
– Evidence 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

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”.

Remote operationBN 3035/95.30
These options enable operation of the ANT-10G
from a Windows®PC. The complete ANT-10G user
interface is transferred to the PC screen via modem
or LAN link. This means that all the functions of the
instrument can be used from any remote location.
The results are simply transferred to the controlling
PC for further processing. Applications include
troubleshooting networks or centralized operation
of testinstrumentation and devicesin the production
and system test environment.
Remote operation via the included Ethernet
interface and remote operation via modem
Provides remote operation via a PCMCIA or external
modem (V.24) which must be purchased separately.
