The assertion that "Alameda does not have TT" is incorrect. The
prefix quoted (415-865) is a 1AESS (I believe it is Alameda 11) which
of course, provides TT. Whether an individual subscriber has DP-only
service is something else again.
This subject comes up all the time. When I did ESS software the
practice was to provide TT/DP >hardware< on all lines. What happened
when a DP subscriber entered TT instead was controlled in >Software<
(Parameters). The choices were (1) Deny service (2) Allow and print a
message on the Maint TTY or (3) Allow and do nothing.rmadison@euler.berkeley.edu (Linc Madison) (06/15/90)

Even if the line is TT-blocked because his aunt doesn't pay the $1.20/month, he should've been able to enter a DTMF tone without problem, after he was connected. The TT surveillance should apply only during dialing. Either the phone wasn't working for TT or the phone company was doing something illegal, even in California.

Personal plea: please include your name and internet address at the bottom of articles in this newsgroup: the way that my system deals with a moderated group makes it difficult for me to reply to messages here without this info (otherwise all my replies go back to Patrick). That's why the attribution of the quote above is incomplete, also.
