I was thinking about the telephone network in particular, and should have made that clearer. The POTS network is (or was!) engineered to the same high standard everywhere and operated largely by a single authority, approved instruments have little variability in quality, and there's no scope for malware. But the NBN requires every telephony user to install some form of modem-router-ATA which is probably built to a price. As far as I know there's no requirement to meet any standard regarding voice quality, transmission quality, software functionality, reliability, & integrity, or network security. And instead of one or a small number of technically competent network operators the NBN Co. website lists 145 service providers. Who is then responsible for the overall quality of this essential public infrastructure? Nobody as far as I can see. > ISPs have been after commodity, user supplied "CPE" (strictly CE) for over a > decade. The level of testing has also been dropping.

Fit for service. Exactly!!! David L. _______________________________________________ Link mailing list [email protected] http://mailman.anu.edu.au/mailman/listinfo/link
