Forget modems - to probe via some kind of analog connection, just get a single instrument wireless telephone with answering capability. For a bonus, put some kind of identifier in the answering message: No power > no answer; power > answer.
I must be thick - how does that solve the problem? The OP wants to know if a modem at a remote site will answer the phone. Maybe I misunderstood the problem.
I'll join the confusion--I thought the OP wanted to test for power availability at the distant site by seeing if a modem there would answer the phone there. That it HAD to be a modem in that case makes no sense to me. I'm of the line now and have been for a while and maybe y'all don't do things the way we did--we always had an answering machine (two or three in some places*) that always answered on the first ring and gave some kind of status report that was updated hourly on on event). If it did not answer, the power was out. *at one site we had one that gave general status--what's up, what's down, what's generally interesting (outages scheduled soon, where we are in the daily batch cycle). We had another listing southern region outputs ready for pick-up and one listing northern region stuff. -- sed quis custodiet ipsos custodes? (Juvenal)
