Vector Faxing System

Abstract

The vector faxing system based on USB fax modems is presented. The system was implemented and made available to users. In the adopted approach, a vector of USB modems does replace solutions based on standalone fax machines, large size of which significantly hampers the construction of a multiple line faxing system in the PSTN environment (Public Switched Telephone Network) – necessary for the effective functioning of a large company. The abstract control model ACM, adopted in the USB hosts which supports analog modem hardware (including USB fax modem devices), is analyzed. It should be emphasized that explicit discussions of the method of mapping telephone lines to – randomly activated during startup of the fax server – USB fax modems, and of the mechanism for assigning user access rights to designated fax modems, are included. Use of the described system increases immunity to threats such as spam, computer viruses, spoofing, or redirecting to fake websites (phishing). The user communicates with the faxing system by the Winprint HylaFax+ Reloaded client.
