Modems that report line faults
« on: July 19, 2018, 12:02:54 AM »

Why do modems not tell us about line faults, chronic ones or the onset of badness "A fault has just developed, of type x?"

Are you now straying into the realm of AI and proposing to add to the logical complexity of what should be a fundamentally simple device?  :-\

Absolutely.

As this is evil from a designer’s point of view, perhaps to make us feel better about this there should be

a set of issues of interest, things which get measured,
an interface for presenting their values in some format
a set of events, which is concerned with various kind of things happening, including these values changing
a protocol for communicating name-value pairs and sending event notifications

A lot of this technology is already in the modem, and to make us feel better the modem can remain dumb in that it does not need to understand the meaning / significant / purpose of these things.

Some agent that connects to the other end of this protocol on a bus of some kind - this is like SMTP which is a monster in my view - can be the bit that has intelligence, even AI, and can have a filter applied to the information and an onwards bus, plus optionally a UI, login and so on. This part is separately upgradeable, so the best software can be obtained and used with all known modems.
