Abstract: A telephone network access adapter for a computer includes a number of line ports for connection to telephone network lines, a subscriber port for connection to subscriber telephone equipment, a video port for connection to video equipment and a computer port for connection to computer equipment. The subscriber interface is connected to the subscriber port. A video interface is connected to the video port. A line interface selectively connects the external telephone line(s) to the subscriber interface and/or the video interface. A controller is connected to the computer port for controlling the operation of the adapter. The adapter is able to connect the subscriber telephone equipment and/or the video equipment and/or the computer equipment to a selectable number of external telephone lines, thus providing a flexible connection to the telephone system.

Abstract: An integrated multi-services access platform includes a time division multiplex interface coupled to a time division multiplex network, a matrix in communications with the time division multiplex interface, a frame relay groomer coupled to the matrix, an asynchronous transfer mode matrix coupled to the frame relay groomer, and an asynchronous transfer mode interface coupled to a frame relay/asynchronous transfer mode network.

Abstract: The present invention provides a system for handling telecommunications signals passed between a first and second element of a telecommunications network, the first element having an interface for transmitting and receiving signals in a first protocol, and the second element having an interface for transmitting and receiving signals in a second protocol. The system of the present invention comprises a first interface unit for receiving a first telecommunications signal transmitted in one of said first and second protocols between said first and second elements, the first interface unit being arranged to separate traffic bearing channels from non-traffic bearing channels within the first telecommunications signal.

Abstract: The present invention provides a bandwidth management system, a subscriber terminal, and a method for managing calls between a central terminal and a subscriber terminal of a wireless telecommunications system, a number of items of telecommunications equipment being connectable to the subscriber terminal. The subscriber terminal is arranged to pass call data between said items of telecommunications equipment and the central terminal via a wireless link, the wireless link being provided on a frequency channel with a predetermined maximum call data bandwidth for the transmission of said call data. The bandwidth management system comprises a bandwidth manager for maintaining in a storage information about allocation of the predetermined maximum call data bandwidth amongst calls currently being handled on the frequency channel.
