What does EDT mean in TELECOM

History

The concept of EDT has been around for quite some time. The first experiments for EDT began as early as the 1970s, though they were not successful due to limited technological capabilities at the time. By the 1990s, more advanced devices were becoming available that enabled better performance for such systems. Since then, many different systems have been developed using both analog and digital technologies that utilize sign language and other modes of communication (e.g., text messaging) to create a bridge between those with hearing issues and their peers in society.

Technology

EDT is based upon an analog system called Loop Telephone System (LTS). This was designed by Philips Electronics in partnership with KPN Telecom BV/KPN Telecom NV (Royal Dutch Telecommunications) in order to provide telephone services to people who are deaf or hard-of-hearing. This LTS would be initiated by dialing 0-800-567-2345 from any standard telephone handset using pulse signaling so that it could alert someone from KPN Telecom BV/KPN Telecom NV when an incoming call was coming through on the system. These calls would then be routed directly like normal voice calls through any public telephone network (PSTN) or private switchboard network (PBX).

Unlike conventional voice networks where sound waves transmitted via microphone are used for communication, EDT utilizes a “loop” system which transmits electronic signals instead — allowing for two way conversations over a wide area without compromising sound quality or clarity of speech during conversation among participants near or far away from each other. In addition, because they do not rely on electric current like voice networks do, these signals have a much higher reliability rate than traditional phone systems which makes them ideal for long distance communications as well as day-to-day interactions between individuals living apart from each other but still wanting to remain connected easily and conveniently.

Benefits of EDT

The primary benefit of using EDT is having access to reliable telephone service despite disabilities that may make communicating over regular landline telephones difficult or even impossible for some individuals with hearing impairments/losses. With EDT devices users can easily switch lines when needed while enjoying clear audio — conducted through headphones rather than a separate microphone — which greatly reduces reverberation found in traditional speaker phones and reduces background noise significantly as well providing optimal privacy no matter what environment users find themselves in since no external speakers are involved during contacts made through this system either locally or remotely.. It also provides full duplex conversation/dialogue capability just like regular landlines do allowing both parties involved in conversations greater freedom when talking back & forth quickly & efficiently without interruption regardless of physical distance separating them from one another.
