There was recently discussion over reading utility meters either by radio or via telephone. A news article in the Saturday, 9 June 90 issue of the Wilmington (Delaware) {News-Journal} indicates that Diamond State Telephone is presently seeking approval to offer meter reading services to utilities in its area. The system is the same as has been discussed in these pages before: the company calls your home with a method that does not ring your phone, and the unit attached to the meter and phone line sends the data requested. As in the other system, if someone picks up the line while the data transfer is going on, it is cancelled and the user has access to his phone line. The data request call is tried again later. Some interesting points from this article that I had not seen in prior postings: "...the utility's computer sends its customers' telephone numbers into the automatic meter-reading equipment, which in turn dials the customer using a special line so the subscriber's phone doesn't ring..." "...A call takes only seconds and will be made between midnight and 6am,when calling volume is lightest, said [Douglas R.] Smith [manager of regulartory matters for Diamond State]..." "...Water companies have been the first to take advantage of the service ...but in the future, all metered utilities -- electricity, gas and water -- could be hooked into the same system ... if all the utilities work together...." "...The system is working in New Jersey and in the trial stage in Pennsylvania ... Hackensack Water Company is its [New Jersey Bell's] largest customer with 170,000 meters attached to the service. Four other water companies are in the process of adopting the system..." "...According to the application filed with the PSC, utilites would pay a non-recurring charge of $1,500 for the central office special access circuit, a monthly rate of $410, plus 3 cents a call in off-peak hours..." Two quick comments: I'm assuming that the "special access circuit" between the utility and the central office would be a dedicated line. I'd hate to think that it would be a switched circuit. There probably isn't a whole lot of info you could get from 'cracking' a utility reading system, but if you take that datum with all the others you can get on a residence, it might pose a security risk. I know, rather far-fetched, though. The other thing is a little less serious. If the utilities are charged a non-recurring fee of $1,500, does this appear on their third bill? And does it continue to appear on other bills even when they tell the phone company to remove the "extra non-recurring charges?" ;-) - tom internet : mvac23!thomas@udel.edu or thomas%mvac23@udel.edu uucp : {ucbvax,mcvax,psuvax1,uunet}!udel!mvac23!thomas Europe Bitnet: THOMAS1@GRATHUN1 Location: Newark, DE, USA
