The electromagnetic teletypewriter
eventually yielded to satellite communications--modern printers bearing signal translation devices, such as the UYK-20 (64K RAM) and TT-624 medium speed printers.
SCORE, a project of the Signal Corps Advanced Research Project Agency, demonstrated that voice, teletypewriter
, and multiple teletypewriter
signals could be received, stored, and then retransmitted by an orbiting satellite.
In that case, the significant financial burden imposed upon the telecommunications provider did not constitute unjustifiable hardship given the budget of the service provider and the benefit to users of teletypewriter
To express it in simple technology, data reduction can be a cathode ray tube (CRT) display on a TV type screen on command or sequentially controlled; a teletypewriter
for recorded display; or both.
This family of shelterized multiplexer and transmission equipment and associated switching equipment provided automatic analog telephone circuit switching and point-to-point teletypewriter
For people with very limited or no usable hearing, Telecommunication Devices for the Deaf (TDD) or Teletypewriters
(TTY) are available for people to type messages through the telephone lines.
People using teletypewriters
(TTYs) or telecommunications devices for the deaf (TDDs) may call (877) 486-2048.
We wanted to get this system to run on anything from teletypewriters
, which were very common at that time, up to and including minicomputers with multiple windows on vector displays.
Peavey therefore installed communicating teletypewriters
at elevators and transmitted market quotations and other data to these units via a private-line teletype network.
Some of our hearing-impaired employees use teletypewriters
to visually communicate over telephone lines.
Hearing aids, teletypewriters
, tele-communication devices, communication boards and interpreter services, in the case of auditory impairments (teaching sign language, lip reading, or finger spelling fall more appropriately within the realm of person-focused interventions), are among the devices used to compensate for sensory (i.e., hearing and vision) loss.
Using facsimile transmission and teletypewriters
, individuals at 280 at these locations are as close to their distant colleagues as the nearest terminal.
