Building a digital network : data communications and digital telephony, 1950-1990 / Bryan Dewalt.: NM97-2/1-2E-PDF
"The period between about 1960 and 1990 was marked by major changes in the technology and organization of telecommunications in Canada and the rest of the industrialized world. The key to this change was the evolution of a versatile, multipurpose network. By converting all types of information to digital pulses, this network could accommodate everything from telephone conversations, to written messages, to computer data, to photographs and moving pictures"--Abstract., p. 4.
