Abstract

A method and apparatus for transferring high data rate data between a pair of separated high data rate buses comprising storing a group of high data rate data from one of the buses, one of which is connected to a digital telephone set, reading the stored data at a low data rate, conditioning the low data rate data to remove high frequency components therefrom, applying the conditioned data to an unshielded cable for transmission to the separated other high data rate bus, receiving and storing the conditioned data from the unshielded cable and reading the stored conditioned data at a high data rate to said other bus.
