Disclosed is a modem with custom ringing detection as a means for automatically determining the content@) of incoming telephonic signals, for example, voice, audio, data, fax, images, and the like, prior to "answering" the signal. Thereafter the modem directs the incoming call signals accordingly, such as, to a human recipient, a facsimile printer, a computer for processing or electronic storage, and the like. Implementation of the modem comprises equipping the modem with appropriate hardware or software that recognizes various incoming ring pattern signals and provides the appropriate logic and switching capability to properly direct the signal. Exemplary modes of operation of the modem include: call answering at predetermined baud rates; call answering at specific times; non-answer; always answer; non-answer with call back later; limiting call or transmission length; and the like. The modem includes, for example, for incoming fax transmissions, the capability of automatically adjusting the baud rate of the receiving device for optimal performance. The modem can be used in conjunction with, or as complement to, remote interactive communications technology that is used with many copiers and electronic printing machines for monitoring and maintaining production performance and operability.
