Hey Tocket
It a marketing term over here that means it's normal ADSL over POTS (plain old telephony service) but with it disconnected from any exchange service therefore naked of telephony services.Why is it called naked DSL anyway?
It comes about as we have a carrier (Tel$tra) that has a monopoly over the copper in the streets that charges all other ISP's rental to use the copper for ADSL, this rental cost used to include telephony services even if you didn't use them, so eventually they agreed to suppling services that has a reduced rental cost and no telephony services on it and called it naked.
