Rj. Read et al., MODEMS FOR THE GENERAL SWITCHED TELEPHONE NETWORK - DEVELOPMENT, DESIGN AND THE FUTURE, Electronics & communication engineering journal, 6(1), 1994, pp. 40-48
The paper starts by tracing the history of CCITT modem recommendations
(the V-series) from the 1960s until the present. This leads into a re
view of the methods of implementation used in current products. With c
ost minimisation in mind, an alternative design approach is then outli
ned which offers potential advantages for the simpler, yet currently s
till popular, modem specifications. The paper concludes with a glimpse
into the future by outlining the latest CCITT V.fast proposals.
