Methods and devices of determining the interface class used on a communication pathway are disclosed. The method compares information derived from the communication pathway to information about known interface classes to determine whether the derived information is similar to the information corresponding to the known interface classes. Devices according to the present invention include hardware and computer readable storage mediums having encoded instructions for carrying out the method.

Interface class discovery method and device

A telephone system wherein all the functions of a digital telephone can be accessed and implemented on a personal computer alone, thereby eliminating the need for a telephone set. By means of the computer display and mouse, keyboard or other input/output command devices, a user accesses and implement all digital telephone functions without the physical telephone set, the personal computer also providing the audio function. A graphical representation of a telephone set or other telephone-related form is provided on the computer display and accessed by the mouse, keyboard or other command device, this being accomplished by a computer program providing graphical interface implementation. A significant advantage of the system is computer access to and utilization of digital telephone functions from a remote location with communication via Internet, LAN, WAN, RAS or other mediums.

Digital browser phone

A telephone communication system utilizing a virtual phone wherein a telephone switch or similar digital switching device, a digital telephone and an external device such as a personal computer (PC) or other processor are generically interfaced. The virtual phone generic interface is configurable and comprises a set of virtual phone data structures, internal and external virtual phone application program interfaces, and an external transfer protocol. Software designated an abstraction layer provides communication between the internal virtual phone application program interface, the telephone switch and the telephone set. The generic interface converts proprietary telephone switch or external interface application protocols into a common format and functions as a protocol interpreter between proprietary switching system protocols and protocols of various applications.

Virtual telephone

A method and device for allowing dissimilar networks to transfer information is disclosed.

Device and method for network communication

A universal line driver interface which enables a digital telephone computer/telephony interface to configure itself automatically or on the fly to accommodate different PBXs. The interface is connected to a PBX and to a digital telephone. The interface also is connected to network interface logic. A microcontroller, which is part of the computer in the computer telephony system, is connected in controlling relation to the interface and to the interface logic. The microcontroller under program control changes operational parameters in the interface as a function of electrical characteristics of the particular type of PBX to which the interface is connected. The changes in operation parameters of the interface, in turn, are used to configure the interface logic depending upon the type of PBX. The universal nature of the interface is achieved by adaptability to different transmission and receiver voltage, levels and an ability to match a range of telephone line impedances.
