Telebyte Model CFA-24 Cable Farm Automation SwitchTelebyte Announces Release of G.fast Cable Farm Automation Switch

Next-Gen Switch Designed Specifically for VDSL2 Vectoring and G.fast 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 or G.fast 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 (G.fast).

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 G.fast testing requirements. We are very pleased this release coincides with the high demand for ID-337 G.fast Pre-Certification 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.

Telebyte Model VxT-48-DC+ xTalk Emulator for VDSL2 Vectoring Testing Telebyte Announces the World’s First Standards-Based VDSL2 Vectoring Crosstalk Emulator Advanced Solution Simulates Test Loops in TR-249 Issue 1

Telebyte, a US-based global xDSL test equipment solution provider today announced the release of the Model VxT-48-DC+ xTalk Emulator for VDSL2 Vectoring Testing. The advanced, standards-based crosstalk emulator is now available worldwide and answers the growing need for repeatable, configurable test equipment for physical-layer testing per TR-249 Issue 1.

True to expectations, millions of Vectored VDSL2 lines have now been deployed and the future looks bright for a continuation of this trend. Service providers who are eager to profit from consumer demand for next-generation entertainment and business applications may now utilize the VxT-48-DC+ to help accelerate implementation of Vectoring on existing copper lines. At the same time, equipment manufacturers are now able to assure service providers that their product complies with the standard.

Until today there has been no common platform for physical layer testing of Vectored VDSL2 equipment that matched the requirements of TR-249 Issue 1. This includes emulation of five independent test loops over 48 channels and complex mechanical interruptions on the CO, midpoint and CPE side of the loop. The only choices have been Cable Farms where correlation of test results from site to site can be problematic. The VxT-48-DC+ offers a reliable and automated way to determine performance and comply with the standard.

"We were waiting for ratification of TR-249 to release a fully compliant crosstalk emulator," said Michael Breneisen, President of Telebyte. “Participation in the Broadband Forum standards meetings has allowed us to be involved in the process as well as anticipate the final requirements as early possible. We already have installations at several major service providers around the world. Many of them own multiple units and use them in different locations. We also see the VxT-48-DC+ used to supplement testing with Cable Farms.”

The VXT-48 emulates the symmetric model of the ATIS Multiple-Input Multiple-Output (NIPP-NAI-2009-014R3) on 48 channels (using the upper-left 48 x 48 quadrant of the 100 x 100 random-drawn matrix). It also models crosstalk between xDSL multi-pairs within a cable binder. Remote commands or the VxT Control Center software may be used to control line lengths and mechanical interruptions settings.

Telebyte’s full line of VDSL2 Vectoring physical-layer test equipment also includes products for noise generation, injection, capture and analysis of alien crosstalk, RFI, impulse noise and more.

Telebyte Launches Live VDSL2 Vectoring Demo Tour at Fixed Access Networks Summit in Berlin See Effects of Real World Noise on QOS

Telebyte, Inc. announced today that it will launch a series of live demonstrations at different venues that include testing per TR-249i1/WT-249i2 and the effects of real world noise on VDSL2 Vectoring. The first of these will be at the Fixed Access Networks Summit taking place on April 8th - 10th 2014 in Movenpick, Berlin, Germany.VDSL2 vectoring is a cost effective strategy employed by an increasing number of service providers to accelerate their superfast broadband rollout. Essential to that plan is the Quality of Service (QOS) for demanding customers. Noise can degrade that QOS resulting in consumer dissatisfaction. Service providers cannot be certain they are truly ready for mass deployment until their testing has faced the noise challenge.

While vectoring works by cancelling crosstalk between a group of VDSL2 lines, it does not cancel a wide variety of noises that can bombard the vectored group. These noises include Alien Crosstalk from lines outside the group, impulse noise, and RFI as well as interruptions of the signal due to physical imperfections on the line. The impact of these disturbances must be investigated to see how they affect data rates and stability – essential to QOS.

Visitors will see live demonstrations during the summit, showing the effects of complex noise and mechanical interruptions (micro-interruptions, single-wire interruptions, micro-shorts and disorderly leave), on VDSL2 Vectoring and learn about the importance of real-world testing prior to deployment. Equipment will include a DSLAM and several modems along with Telebyte’s suite of VDSL2 Vectoring test products, including their 48-channel VxT-48 Crosstalk Emulator, 48-channel VxT-N48 AWGN Generator/Injector, 4901 Multi-Ouput Noise Generator and 500 Field Noise Capture system.

Model 500 Field Noise Capture SolutionTelebyte Announces Release of DSL Field Noise Capture Solution

VDSL2 Vectoring Testing Can Now Include Live DSL Noise from Your Telephone Network

Hauppauge, New York, USA - Today Telebyte, a US-based global xDSL test equipment solution provider, announced the release of its new DSL Field Noise Capture Solution. The unique, portable solution is able to capture, analyze and monitor noise on live DSL lines in a telephone network. Authentic Impulse, Crosstalk or RFI noises can be captured and then saved in a variety of formats or prepared for export to Telebyte’s Model 4901 noise generator to facilitate injection into a test set up. Service providers can now work with more realistic testing scenarios and fine-tune testing requirements for equipment vendors that include these highly relevant noises.

“We have already used the solution in a field trial with a major North American service provider. Customers are excited about this new offering and intrigued with the possibilities. They can now bring live noise in their specific network back to the lab or leave a unit in the field to remotely monitor or capture.” said Michael Breneisen, President of Telebyte. “As VDSL2 Vectoring continues to take hold, Service Providers are seeing that noise is causing complications that must be dealt with if they want to be certain of performance. What could be better than to have the noise that’s actually occurring in their own network?”

The innovative 30MHz solution is suitable for ADSL2, ADSL2+ and VDSL2 lines and includes a high-performance system loaded with Telebyte’s DSL Field Noise Capture software; one 16-bit, 105MS/s capture port; a 17” built-in display and a nonintrusive differential probe. The user attaches the probe to a DSL line and selects one of three modes: 1) Noise Capture Mode for continuous capturing and recording to the hard drive of Crosstalk, RFI, or Impulse; 2) Noise Monitor Mode where Impulse is captured and recorded based upon voltage level and sample-quantity/length triggers; or 3) FFT Spectrum Analyzer Mode for full-featured, real-time analysis with plots of PSD’s and waveforms in the time domain, probability densities, mask testing and more.

This new solution is evidence of Telebyte’s continued dedication to the needs of an evolving DSL marketplace. The release of the Field Noise Capture Solution comes after the high-tech company’s announcement of its groundbreaking VxT-48 xTalk Emulator for Vectored VDSL2 Testing and its VxT-N48 (48-channel AWGN generator and noise injector). According to Breneisen, the company will continue to focus on new offerings for this product line.

Telebyte Model VxT-N48 48-Channel AWGN Generator/InjectorTelebyte Releases Industry’s First Noise Solution for Testing VDSL2 Vectoring Devices

High-Density Injection of Complex Noise for More Realistic Testing of VDSL2 Vectored Lines

Hauppauge, NY USA (June 17th, 2013) – Telebyte, a leading supplier of DSL physical-layer testing solutions, today announced another breakthrough in VDSL2 Vectoring layer 1 testing equipment with the release of the Model VxT-N48 48-Channel AWGN Generator/Injector. The unique product generates or injects the noises needed for more realistic testing of next-generation vectoring-enabled devices.

The Model VxT-N48 is designed to interface between CO or CPE equipment and the Telebyte VxT-48 xTalk Emulator for VDSL2 Vectoring Testing. It will generate 48 channels of built-in, uncorrelated, AWGN or inject up to 48 correlated or uncorrelated complex noises received from Telebyte’s popular Model 4901 Multi-Output Noise Simulator. This makes it ideal for testing per WT-249 (G.993.5 Self-FEXT Cancellation) or for any xDSL application that calls for flexible, dense noise generation and injection.

“A vectoring test solution is not complete without complex noise,” asserts Michael Breneisen, President at Telebyte. “Noise can come from several sources outside of copper transmission lines such as impulse noises from appliances being turned off and on, RFI from radio stations and crosstalk from non-vectored loops within the same binder or cable. Vectoring doesn’t cancel these noises and can actually amplify them. It is essential that these noises are included in the test setup if you want a more realistic assessment of signal quality.”

Service Providers know that high speed does not always equate to high QOS unless interference in properly mitigated. Until now, some have relied upon cable farms alone for testing, leaving them unable to verify fully that complex noise has been dealt with and quality is acceptable. With Telebyte’s growing suite of test gear designed specifically for this purpose, Service Providers now have a solution to help them accelerate their vectoring rollout with confidence.

Telebyte offers an outstanding line of products for local loop simulation, crosstalk emulation, noise generation and automated transparent switching. The high-tech company’s solutions are used for physical-layer testing of xDSL technologies such as G.SHDSL, ADSL, ADSL2, ADSL2+, and VDSL2. In business since 1983, Telebyte (headquartered in Hauppauge, NY USA) sells its products to major service providers and equipment vendors around the world.

Telebyte Model VxT-48-DC xTalk Emulator for VDSL2 Vectoring TestingTelebyte Announces the First Commercially Available Crosstalk Emulator for Vectored VDSL2 Testing
Telebyte’s Testing Solution Supports the Growth of Next-Generation High-Speed Internet Applications

Hauppauge, NY USA - May 12th, 2013 – Telebyte, a leading supplier of DSL physical-layer testing solutions, today announced the release of the Model 700 Series which consists of 15 different Multi-Channel/Multi-Standard Local Loop Simulators with optional AWGN. These highly-accurate, lab-grade simulators are designed for Layer 1 testing of bonding applications where two, four or eight copper loops are aggregated to produce dramatic increases in data rates, reach and stability. Offering eight, twelve or sixteen channels as well as long line lengths and fine increments, customers will also find these products suitable for testing rate-reach applications.

VDSL2 Vectoring dramatically increases data rates on copper telephone lines through cancellation of crosstalk between loops within and across cable binders. As the growth of DSL continues to overtake both fiber and cable combined, implementation of Vectoring on existing copper infrastructure is certain to interest DSL service providers who must keep pace with increased consumer demand for next-generation entertainment and business applications. The VxT-48 will help to accelerate that implementation, giving service providers a faster return on investment and helping them avoid the delay and high capital expenditures that come with investing in Fiber to the Home (FTTH). A reliable testing platform will also fast track universal broadband projects now mandated in many countries.

"With VDSL port shipments expected to continue their growth during the next five years, driven by new deployments, replacement of ADSL ports, vectoring, and pair bonding, operators require a way to quickly test their VDSL connections to ensure they are performing as advertised," said Jeff Heynen, Directing Analyst, Broadband Access and Video at Infonetics. "Telebyte’s technology gives operators that physical layer testing capability required to speed up their vectored VDSL rollouts."

Until today there has been no commercial solution for physical layer testing of Vectored VDSL2 equipment. The only choices have been Cable Farms where correlation of test results from site to site can be problematic. The VxT-48 offers a reliable and automated way to measure the effect of vectoring on 48 line pairs, allowing service providers to compare and correlate test results with equipment vendors and from one location to another. This makes it ideal for performance testing.

"As soon as we saw that Vectoring would be a game changer for the industry we began working on a way to answer the testing challenge," said Michael Breneisen, President of Telebyte. “As a leader in broadband test equipment, this was a natural evolution for Telebyte. We are the only company offering a commercially available Vectored VDSL2 test solution."

The VXT-48 emulates the symmetric model of the ATIS Multiple-Input Multiple-Output (NIPP-NAI-2009-014R3) on 48 channels (using the upper-left 48 x 48 quadrant of the 100 x 100 random-drawn matrix). It also models crosstalk between xDSL multi-pairs within a cable binder and is sufficient for automatically running test cases for systems with vectoring capabilities. Remote commands or the VxT Control Center software may be used to control line lengths and micro-interruption settings.
