Next-Gen Switch Designed Specifically for Automating and VDSL2 Vectoring Testing

The only switch on the market that automates testing.

Telebyte, a US-based global xDSL test equipment solution provider, today announced the release of the Model CFA-24 Transparent Cable Farm Automation Switch - the only switch on the market designed for testing the Broadband Forum’s ID-337 and TR-249.

The 24-channel, electrically neutral device allows up to twenty-four incoming cable farm lines to be switched to five different copper loop segments. Operating in a frequency band up to 212 MHz, the CFA-24’s superior performance and transparency facilitates lab-grade testing of VDSL2 Vectoring (including Profile 17a and Profile 35b) or devices where accuracy is extremely important.

The CFA-24 is the company’s first product designed for programmatic control of multiple copper loop segments. Line lengths and increments are set without re-cabling. The user makes connections once then switches loop segments in (or bypasses them) as needed through a web browser. Remote commands can be used to set line lengths for test automation. Additional features include Micro-Interruptions and support for Reverse Powering (

In keeping with the modular approach to most of Telebyte’s products, units may be added as testing requirements expand or budget becomes available. This allows customers to purchase an initial system and later extend the number of loop segments to as many as fifteen and/or expand the number of channels to as many as needed by purchasing additional units.

“Our customers were looking for a way to avoid connecting and disconnecting loop segments in their cable farms manually. They wanted to simply switch in or bypass segments programmatically,” said Michael Breneisen, President of Telebyte. “Customers reported dissatisfaction with other products that were repurposed for this type of testing so we decided to design a product from the ground up to meet both VDSL2 Vectoring and testing requirements. We are very pleased this release coincides with the high demand for ID-337 Certification testing and TR-249 testing.”

Finally, the CFA-24 may be used with Telebyte’s noise generators and injectors to add alien crosstalk, impulse, RFI and more for realistic testing.
