GAO RESEARCH Corporation.——-V.22bisV.22 Modem Software

Toronto, Canada – GAO Research Corporation. (world wide has introduced the supply of their V.22bis & V.modem software, which implements the ITU-T standards for 1200bps and 2400bps full-duplex data communication around the GSTN as well as on point-to-point two-wire leased line circuits. It uses minimal memory and MIPS and does not require a top quality, expensive DDA or Codec. The modem software programs are deployable on processors for example TI C5000 and C6000 DSPs, ARM processors in addition to a number of other DSPs and microprocessors. It runs under all major RTOS including Home windows, Linux, ITRON, VxWorks and pSOS. The program is carefully examined for standards compliance using TAS, Consultronics, Rochelle, Advent and Telegra equipment under various funnel models based on the relevant ITU or TIA, EIA, BellCore, and Mitel standards. It has additionally been examined against various impairment combinations using TAS Telephone Network Emulator. The softmodemsuse frequency division for funnel separation and every funnel is phase change modulated. An emblem rate of 600 carries 2bits per symbol for a price of 1200bps for V.22. For V.22bis, each funnel is quadrature amplitude modulated (QAM) to hold 4bits per symbol at 600 symbols per second for a price of 2400bps. Additionally, company wavelengths are 1200Hz and 2400Hz correspondingly for that low and channels. About GAO Research Corporation. GAO Research Corporation. (world wide is really a recognized worldwide leading provider of communications software to telecom and electronics companies and offers probably the most comprehensive and different suite of modem, fax, telephony, speech software, Voice over internet protocol, FoIP, fax relay and fax/modem/voice relay software for embedded programs for DSP and microprocessors.
