TTD/TTY devices use normal phone lines to communicate. An individual with a TTY/TDD can either communicate with another TTY/TDD device or can make a call to a standard telephone. In this case, the TTY/TDD device calls a live relay operator and the live relay operator communicates with both parties either with a TTY/TDD device or uses their normal human voice on a standard telephone. It is important to note that there are different protocols that can be used to communicate with TTY/TDD devices, however many newer TTY/TDD devices can handle a wide range of protocols and can even communicate directly from a personal computer using special software and a computer modem.

Samsung shows Samsung gt-e2230 and freezes while booting.

Try taking the battery out and putting it back in. This normally works for me. If that doesn't work, take it to whatever carrier you buy your phone from. If they can't fix it, its time for a new phone.

Please describe what is inside a TTY communication device

Your best bet would be to visit a full line phone store.
Look for a clear-phone on display. You would see all the stuff: diodes, sensors, speakers, tiny-bulbs etc. All these items are similar to what's inside a TTY.

Updates are always available online.
If you try to add unathorized gadgets to your TTY, you could have problems. Always check the owners manual for "dos and don'ts."
