I have a few questions that are about the etiquette and the human protocols involved in communicating using a TTY machine. I am thinking about a technology implementation and the answers to these will help me guide some decisions.
1) When you call someone with a TTY device and the call is answered, who first types in the equivalent of "hello"? Is it the person you called or you?
2) If it is the person you called and if you do not see anything in the display, do you then type in something equivalent of "hello"?
3) In that case, normally how long ( in seconds ) do you wait for that "hello" coming from the other side before you decide to start the conversation.. Is it like a 2 to 3 seconds or 10-15 seconds or > 20 seconds? Just a ball park is good enough.
4) In general, does the TTY device indicate to you if the other side picked up the phone and answered? Asking this mainly because, if you do not get anything back from the other side, how will you know if they answered and did not type anything in or the call is still ringing...
5) Say, you are calling a customer service type phone number that is marked specifically as TTY. Do you normally wait for the system to do its thing or you type something first..
6) Say, you are calling a customer service type phone number that is not explicitly marked as TTY capable? If you do not hear anything back from the other side, do you still type something to see if there is some machine that recognizes the tty and send you to an operator with a TTY machine?
7) Do you even attempt to call such customer support type numbers that are not marked specifically as TTY capable?
As you can see, what I am wondering about is about the human factors and how a deaf person deals with these real world situations. This will help make some decisions on the technology.
Thanks for any info you can provide.
