All Plain Old Telephone Service modems (and ADSL modems/modem-routers) use a lead which wires pins 2 and 5 of the BT plug to pins 2 and 3 of the RJ11. All non-Telecom phones use a lead which wires pins 2 and 5 of the BT plug to pins 2 and 3 of the RJ11, so most phone leads can be used as modem leads. Telecom branded phones a.k.a. "rental phones" use a lead which wire pins 2 and 5 of the BT plug onto pins 1 and 4 of the RJ11. These leads will not work with a modem. Cheers, Wayne
