Bell Atlantic helps light the fuse to an explosive new technology
I have merely sumarised this article into the basic facts about ISDN.
In addition to instant facsimile transmission and video-conferencing, ISDN
features include:
-- centralized coordination and administration of Centrex phones within large
companies;
-- city-wide Centrex,allowing inter- building dialing of four-digit numbers
without a prefix;
-- reproduction by printer of onscreen images.
Besides implementing an aggressive digital modernization program in key
central offices throughout the region (221 COs will be digital by the end of the
year,compared to 459 in 1986),the company has introduced two product lines that
position ISDN in the mid-At lantic region: LADT(local area data transport) and
CO-LANs(central office- based local area network).
(LADT provides a LATA-wide public packet switching service,while CO-LAN
provides a switched terminal-to termi- nal or terminal-to-host data
communications service.Both services use a "data voice multiplexer"(DVM), which
squeezes more out of the transmission medium and allows a customer to trasmit
voice and data simultaneously to more than one re- ceiver over the existing
telephone wire.)
ISDN will help customers transmit high-speed facsimile and voice signals
and,at the same time,receive calls and data.
ISDN advances are confined to the U.S. shores,however.
Trials are scheduled to get underway in Japan,Great Britain,France,West
Germany,Italy and Sweden.(In Japan, ISDN is known as INS,or Information Network
System,and in Great Britain, it's called IDA,or Integrated Digital Access.)
get this line guys,true american bureaucratic bullshit and redtape that
regulates fucking everything....
"The movement to migrate to an ISDN network overseas is - for a variety of
regulatory and political reasons - outpacing efforts in the u.s."
In otherwords,cause of the fucking bureaucrats in office,the fucking japs and
shit are moving faster than we are even in the phone systems now cause we have
to many 'regulatory and political' bullshit laws...
that's all dudes
