Computer time-sharing
The first time-sharing computer operating
system was called the compatible time-sharing system (CTSS).
Developed at MIT in 1961, CTSS enabled multiple terminal
users to access expensive host computers at relatively
low cost by time-slicing the processing and by assigning
slices only to jobs awaiting service. This required the
development of appropriate networks to support multiuser
and multitasking environments.
Advances in telephony
Several significant improvements to the telephone
system have allowed effective connection of digital
equipment into a network that was originally designed to
carry only analog voice signals. For example, in the
mid-1960s Bell Laboratories developed automatic
equalization. In automatic equalization a modem can
adapt its bit transmission process to match telephone
line characteristics, thus achieving data rates of tens
of thousands of bits per second. Bell Laboratories also
designed the T1 carrier system for telephone
transmission. First installed in 1962, the T1 system
provided digital transmission of voice signals by
time-multiplexing 24 voice channels, each using a
64-kilobits-per-second data rate, into a
1.544-megabits-per-second pulse stream in the article
telecommunication). Digital transmission from end to end
is required for implementation of the integrated
services digital network (ISDN), described below.
