Selection of ready-to-run applications and
graphics-supported test settings
The graphical method for making test settings is unique. The way that
the ANT-20SE is connected to the device under test, the protocol layers
and settings included in the test, or the ATM services to be tested can
be quickly and easily seen. Users can select from a range of pre-defined
test setups or customize their own. Pre-defined 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, circuit type, header, traffic contract, traffic source.
An editor program is provided for defining the test circuits.
Direct testing of all contract parameters
Some of the main tasks facing measurement 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 that allows all the
major service parameters to be set and measured.
For such applications, the Broadband Module includes an editor that
permits all of the contract parameters for the various ATM services to
be set for the first time.
For terminal emulation, all contract characteristics and of the traffic
model used for the test can be defined with the Channel Editor.
After starting the measurement, the ANT-20SE generates test traffic
using the selected parameters. This allows direct demonstration of the
way that the ATM network handles the user traffic and whether the
agreed network resources were 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.
