Basically, people use teletypewriters in the newsroom before the age of cell phones and the internet. They would sit in a row and raid and make a lot of noise. We cannot send messages from one end of the country to the other using the existing telephone network. Like the internet, email and mobile phones, the teletype writer took the back seat. Now, people use this only for people with hearing or speech impairments.
A teletypewriter (TTY) is an input device. It allows alphanumeric characters. So that they can type and send. Usually, one at a time in a computer or printer. Teletypewriters are a very old technology. But now people use it to give access to new mediums to deaf or hard of hearing people.
How does TTE work?
The TTY device is like a typewriter with a small display screen. Depending on the model you are using, it can print the message. The device connects to a compatible cellphone using a TTY cable and will essentially act as an SMS device. Also, and you can communicate with anyone else who has a TTY device.
TTY mode means legacy technology and many people can use SMS to communicate to listen or deliver a speech. There are also real-time IP technologies to facilitate communication, but this requires a data plan or digital telephone line. TTY mode is designed for people who do not have access to mobile data or who have some control over the analog phone line. Accessibility leads the way, but it is still not ubiquitous.
You type your message on a teletypewriter and check it on the screen. When you submit it, it goes to the phone via TTY cable and sends it through your carrier. The receiving end will receive the message and read it directly over the phone or through its own teletypewriter.
How to use TTY mode?
If you have a compatible handset, TTY mode is easy to use. Of course, you will need a teletypewriter, TTY cable and your phone. Typically, the TTY cable will connect to the audio jack. Then you have to turn on TTY mode and go from there.
Types of TTY are Complete, HCO and VCO. Full TTY means that there is only text-communication on both sides of the phone call. HCO stands for “Hearing Carry-over” which means you hear a voice reading incoming text and you type outgoing text. VCO stands for “Voice Carry-over” which means you speak outgoing text and retrieve a text message as your incoming communication. HCO settings are usually enhanced for hearing difficulty. Be careful with headsets and hands-free earpieces when enabling HCO due to this increased volume.
When you enable TTY mode, other phone functions may not work properly. Depending on the phone, you will not be able to use SMS or normal voice calls when it is enabled. So, if you don’t use a teletypewriter, it makes sense to turn off the setting to gain access to the full functionality of your phone.
There are usually four settings to choose from: TTY Off, TTY Full, TTY HCO and TTY VCO.Absolutely straightforward, as what it means TTY mode is not enabled at all.It is intended for text-only communication without any audio components.
