Abstract
An apparatus for connecting a data communication equipment, such as a data terminating equipment (DTE) to an ISDN digital communication network providing a first 64 kbps and a second 64 kbps B digital communication channel which involve different transmission delays. The apparatus includes a transmit part with a separation for separating a unique high rate 128 kbps data flow into two distinctive 64 kbps data flows to be transmitted through both B channels. The apparatus includes a receive part (9999) including storage for storing the data received from digital network, measurement and comparison circuits for measuring the difference between the two transmission delays, address generators for addressing the storage in order to extract the data received through both digital channels, control circuits responsive to the measure and comparison for controlling the address generators in order to provide a 128 kbps which is not affected by the difference of transmission delays introduced by both digital channels. The invention is particularly well suited for transmitting simultaneously multi-media data, i.e. voice, video and data.
