GAO V.22bis Package Targets Set-Top Box Market

Introduction

V.22bis modems will continue to make up a significant portion of the modem market as long as short transactions, such as credit card checks, are popular. The recent boom in set-top boxes has further increased the demand for V.22bis modems. Software implementations of V.22bis that are based on DSPs offer more cost-effective solutions than hardware modem chip sets in many applications. GAO Research and Consulting Ltd. is releasing a software package, which offers V.22bis and its fallback functions, to assist product design engineers in reducing costs and time-to-market.

Media Release

Toronto, Canada: GAO Research & Consulting Ltd., a leading supplier of modem technology, has released a new version of its V.22bis modem software package (GAO V.22bis Package) targeting the set-top box market. The GAO V.22bis package is implemented in assembly languages for the ADSP21xx family of DSPs from Analog Devices and the C54x family of DSPs from Texas Instruments. GAO V.22bis Package complies with the appropriate Bell and ITU standards and has been tested using a TSB37A model and a TSB38 test suite. The package includes V.22bis, V.22, V.23, V.21, Bell 103, Bell 212A, V.42, V.42bis, and AT commands as well as hardware reference designs for the DAA and codec. The GAO V.22bis Package can also be easily customized to suit any specific requirements. With all this included in one package, both the cost and the time to market of a customer’ 9s product are reduced.

Although V.22bis technology has been around for some time, these modems continue to make up a significant portion of the modem market. The popularity of short transactions such as credit card checks and the recent boom in the demand for set-top boxes have further increased the demand for V.22bis modems. GAO V.22bis is ideal for embedded modem applications which require a rate of 2400 bps or less. Such applications include set-top boxes as well as point of sale terminals, fax relay systems, satellite receivers, utility meters, and network control.

Software implementations of V.22bis modems that are based on DSPs offer more cost-effective solutions than hardware modem chip sets in many applications. By running a software modem directly on a DSP along with other application software, an OEM can save on the system costs that would be incurred with a combination of a modem chip set and a processor for application software. Licensing V.22bis software from GAO Research & Consulting Ltd. can save expensive engineering time and, because GAO V.22bis is ready and well tested, it will shorten your time to market,” said Dr. Frank Gao, CEO of GAO Research & Consulting.

GAO also offers a complete suite of modem software including ADSL and 56K, in fixed and floating-point C, for microprocessors such as Pentium and ARM, and in assembly languages for DSPs such as TMS320C6x/54x and ADSP21xx.
