I remember many years ago, when phones had to have a little green triangle on the packaging, to show they had been officially approved. You could buy cheaper phones and modems, but if they didn’t have the sticker, you were officially breaking the law! All the interesting hardware was often imported from Asia, with no approval having been paid for. One of the get out clauses used by an ISP I worked at, was that if a customer’s phones and modems did not have the BT approved triangle, that was the reason their internet connection was slow (back in the days of 56k dial up). Obviously some customers actually believed this and went and bought new hardware. Sadly, in the majority of cases, the internet connection did not improve. Having said that, I can’t remember the last time I saw anyone questioning the REN (ringer equivalency number) of a person with telecommunications difficulties. Anyone know if the limit has been raised from 4?
