Fellow TREGers, I think that that use of the negated switch symbol is a use that does not fall under the TTE Directive at all. The TTE Directive defines that symbol for use on a product in conjunction with a CE marking, not on an interface on a product, as a indicator of that product's non-compliance with the harmonized standards which the consumer would otherwise expect it to conform to. The directive speaks of a product which "is capable of being connected to the public telecommunications network, but is not intended for such purpose." It further says that if the negated switch symbol is used as defined, the manufacturer or supplier must submit documentation to the notified body in the country of first placing on the market and be ready to defend its use.
An RS232 port on a RJ11 connector is not capable of being connected to the PSTN in any but a physical sense, so it doesn't warrant the symbol. An analog phone which is designed for a special purpose but could be expected by an uninformed user to function on the PSTN does. So, if you stick it next to the RS232 ports that use RJ11 plugs, that has nothing to do with the TTE directive, but it certainly perverts the symbol's intended use. Maybe that's why the notified bodies are rumored to be very negative toward its use under the TTE Directive. Dick Shultz Compliance & Approvals Manager Brooktrout Technology, Inc.
