ABSTRACT:
One, or more, ISDN interfaces have their reach extended without violating ISDN interface standards by a method which converts ISDN coded information which is to be delivered over an extended channel into binary coded data prior to transmission, transmitting the binary coded information to a receiver at an extended location and there, after storage, and assembly, converting the binary coded data into ISDN specific coded data for delivery to an ISDN interface.
