【Abstract】 Based on PSTN (Public Switched Telephone Network) G3 fax communication technology and CDMA (Code Division Multiple Access) cellular mobile communication technology, CDMA wirless fax data service is researched in this article. In order to make the fax communication control more flexible and more adaptive to complex wireless environment, a system solution of analogy fax service of CDMA wireless fax data services is presented in the article. On the basis of analysis about system solution of CDMA wireless analogy fax communication system, as the article key, the design and implementation of CDMA wireless analogy fax accessing terminal is elaborated on. The design and implementation of hardware of CDMA wireless analogy fax terminal is expatiated on, which makes use of MSM5105 chipset and fax MODEM CX06827 chip.Based on TIA/EIA IS707A.7 protocol and TIA/EIA 578 protocol, the design of analog fax module and the particular analog fax flowchart are described with the solution of flow control and timer. The experiment shows that the terminal equipment has good system compatibility and fax success ratio and quality has achieved the anticipated effect. Finally, summarize the current system service condition and the existence insufficiency, point out the direction hard in the future.更多还原
