I do not think expansion of TTY to Teletypewriter is a good idea. That 
tends to mean the other use of the term TTY, the device that was often 
used as a computer operator console terminal a long time ago and still 
lives in language around such usage.

So TTY in this usage is more " A term used in North America for text 
telephones, i.e. devices used for text and audio communication in the 
PSTN mainly with deaf and hard-of-hearing persons."

Text telephones or textphones is the international term used by ITU-T ( 
E.g. V.18 and F.703 )  3GPP ( e.g. TS 22.226 )
IETF ( e.g. RFC 4734 ).
Various countries in Europe have different names for the concept in 
their national languages, so text telephone is not specifically European.

I hope it is clear by combining TTY with text telephone what it referred 
to, so that we do not need to drag in a long descriptions of a 
peripheral item into the spec.
