Abstract
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.
