Abstract: A TDM PCM telephone system and a telephone user terminal are interconnected by a digital subscriber loop circuit which provides at least a single channel communication path for digital signals of data or encoded voice origin. The digital subscriber loop circuit includes transmit and receive paths and a line interface circuit. The line interface circuit converts a selected channel of binary signals appearing at a subscriber line port of the telephone system into a corresponding bipolar return to zero (BPRZ) signals for transmission on the receive signal path. The line interface circuit also converts BPRZ signals from the transmit signal path to corresponding binary signals. These binary signals are accumulated and stored. At a time coincident with the selected channel occurrence, the line interface circuit transmits the stored signals to the subscriber line port for acceptance by the telephone system. In one arrangement, the digital subscriber loop is interfaced at opposite ends by a universal line interface circuit (ULIC) which provides for compatible use with two TDM signal formats and with any one of a plurality of commercially available single channel codecs in the associated telephone user terminal.

Abstract: Sheet feeding apparatus including a cylindrical tube (80) mounted above a stack of documents (62) for separating individual documents from the stack. The cylindrical tube (80) houses a rotatably mounted shaft (90) to which are secured a series of spaced beater (112) and turbine (110) blades respectively. The cylindrical tube defines a series of apertures along its bottom surface which are aligned with the beater blades and allow the beater blades to extend outwardly into contact with a separated sheet (68). At one end of this cylindrical tube is coupled a vacuum source (86) which when energized rotates the turbine blades (110) and reduces the pressure inside the tube. Accordingly, a single sheet (68) is first separated from the top of the stack by attraction toward the reduced pressure inside the tube and once separated is driven away from the stack by the beater blades (112) mounted to the rotating shaft.
