Sometimes I feel we burn ourselves out "reinventing the wheel" - even where standards exist. e.g. "JTC 1/SC 6 - Telecommunications and information exchange between systems" <http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_tc_browse.htm?commid=45072> Since should not exclude the possibility that some of the operators could be e-dumping old network equipment here, I would suggest one starts by finding out which, if, any and why an operator is not conforming/compliant with set ISO standards..then take up the matter with CCK/KEBS. Success example? All mobicos "air time meters" are now being inspected to ensure that they are properly calibrated to charge by the international second/minute standard. Thanks to standards setting participation at KEBS+some sharp advocacy:-) regards, Alex
