It is a long time since I left the modem business, so I cannot be so authorative about ADSL. An ADSL modem does not need to attach to the third 'ringer' wire. It will attach in parallel to the A and B wires, and will contain a high pass filter to filter out all the ringing and telephone signals. It should therefore not have a REN at all, but in the light of what I said about it making manufacturers lives easier if they do declare a REN I would not be surprised if you were to see a REN number written on the bottom. derek -- ---------------------------------- www.jennings.homelinux.net
