PROCESS AND DEVICE FOR INCREASING THE WORKING RANGE OF THE TRANSMISSION PATH BETWEEN FUNCTIONAL UNITS OF AN ISDN SUBSCRIBER CONNECTION

摘要

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 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.
