Abstract
The facsimile modem of the present invention comprises a computer interface, a switching unit, and a memory unit. The objective of the present invention is this line-switching facsimile modem that can transmit a data demanding the security, high-speed, and low-cost delivery, by prioritizing the usage of the leased line in transmitting this data. The line-switching facsimile modem of the present invention is connected to a facsimile machine and has a function to transmit data via the public switched telephone network. When transmitting a facsimile data from the facsimile machine, the switching unit checks whether a leased line address is registered in the memory unit or not, and if the leased line address is found registered, the switching unit switches the connection from the public switched telephone network line to the leased line, and then the facsimile data is transmitted using the computer interface via the leased line.
