ETTA, the Ethernet Traffic Test Appliance, is an ethernet traffic bandwidth tester. It is an easy to use hand held, powerful test set that is economical
enough to put in the hands of every technician, yet powerful enough to give accurate, reliable test results. It's much more useful than a simple ping checker.
A typical scenario for ETTA is the installation of
Pseudo Wire circuits. Without using ETTA ethernet test set, installing a Pseudo
Wire circuit can literally take days, weeks or even months.
Using ETTA, the circuit path can be evaluated quickly and
easily, and best of all, virtually automatically.
The ETTA can verify adequate bandwidth and jitter performance for VOIP or ROIP installations prior to installing the hardware. Jitter testing is invaluable when troubleshooting streaming protocols. Use it to prove to your connetivity vendor that they aren't providing the bandwidth you paid for, or to verify that your bandwidth problem lies elsewhere. Use the jitter metric to tune end devices for proper jitter buffer operation. This is a practical alternative to using bulky ITU-T Y.1564 test equipment that costs tens of thousands of dollars. This ethernet test set is much more than a simple ping tester... it can fully load the communications circuit for true measurements.
Compare using ETTA to either installing the Pseudo Wire equipment or using some OAM device. Both approaches, the Pseudo Wire equipment or an OAM device can take hours to configure, hours of testing to check performance, and then hours more evaluating results and fine tuning the equipment to fit the applications.
ETTA can eliminate the time consuming trial and error testing with a simple automatic test. ETTA can eliminate hours on the phone with vendors, multiple attempts to fine tune settings. ETTA will pay for itself in a single installation.
Unlike using tools like iperf and PCs for testing, the ETTA can fully load a 100Mbps connection and the test results are accurate, not an artifact of Windows or Linux bandwidth and driver limitations.
For accurate results, an ETTA should be used at both ends of the link. While it will work in conjunction with PC as an echo responder when using the PC Compatibility menu item for the bandwidth echo test, PCs rarely have the actual bandwidth (throughput or PPS capability) to accurate measure high speed transports.

While the ETTA works best in pairs, giving an accurate analysis of the communications path, it’s possible to use a single ETTA in conjunction with a PC for sime bandwidth echo tests. While this approach isn’t as accurate as having an ETTA on each end of the path, it provides adequate results for many uses and is useful for those times when there isn’t an ETTA at a remote site. PCs will only work for with the Bandwidth Echo test.
