various quotations are given on the "undesiredness" of the ANI service
provided by ISDN. Having worked on the Swedish ISDN project (run by Swedish
State Telecom and ERICSSON) for several years, I would like to claim that
the problem is mostly one of information and education.
The users who have seen the ANI service (we call it Calling Party Number
Identification or A-number transfer but yout term ANI is shorter) have so far
reacted favourably. Partly this may be because we haven't as yet reached beyond
the engineers and tech-happies with our demos, but I don't think this can be
the whole answer.
The service, as we've implemented it, where the received numbers are stored
in the terminal for easy call-back has been very well received so far, but I
think the need for information to the users is paramount. The potential for
*very* user-friendly facilities lies within our reach if we don't scare the
users away. This means that the phone-company staff, especially those dealing
with customer contacts and information, must be educated on the possibilities
and consequences of ISDN.

Once users and journalists REALLY find out how ANI works, they will also know
that the subscriber who so wishes can elect to have his number NOT sent to
the other subscriber. This is normally a fixed value, set in the exchange
according to the wishes of the subscriber. Subscribers with unlisted phone
numbers are an obvious example of users who should automatically be set as
"No ANI". As a matter of fact, according to the CCITT spec. the service should
be implemented in such a way that the caller can specify FOR EACH CALL whether
he wants to send ANI or not. The default (to send or not to send) is a central
setting, set by the administration. Then the subscriber can order an individual
setting for his line, which becomes his own default (overriding the central)
and then he has the opition to counter his own default, on a call-by-call
basis, if he desires. So the secrecy-minded user will have his line blocked
against ANI and that's it. If public opinion against ANI becomes strong enough
the default can be set to No ANI and only those specifically wanting it will
get it.
At least, that's the way ERICSSON has implemented it. Maybe AT&T doesn't
offer these choices to the users (heh, heh, heh...)?
Maybe I should have sent this to the RISKS forum, but this is where I read
it. Sorry it grew so long.
E-mail questions on ISDN services welcome.

Does anyone know where I can obtain a DNR (Dialed Number Readout) that operates with pulse and tone dialing? MATCO Electronics used to sell a DNR kit a few years back, however I have not been able to locate them recently. Does anyone know if they are still in business? If see please post the address.
Any help would be greatly appreciated. Thanks.
Bill

I suspect 713, Houston, is in the running as the largest local calling area.
Don't have figures offhand.
