Abstract
A universal digital communication device includes a first digital communications interface for a first type of digital communication signals (such as basic rate 2B1Q ISDN signals), and a second digital communications interface for a second type of digital communication signals (such as extended range 3B1O ISDN signals) having a digital transport range over a telecommunications network greater than that of the first type of digital communication signals. A processor-controlled multiplexer unit determines which of the two types of digital communication signals is required for providing digital communication connectivity between local and remote communications equipment. It then couples the terminal equipment to the telecommunications network by way the digital communications interface that is capable of interfacing the required digital communication signals with the telecommunication network.
