Cannot send or recieve faxes

You cannot send a fax on a broadband connection, they should have given you a splitter, if not get one, the splitter is a small box like thing, it has two telephone sockets on one side and one socket on the other, the telephone line from the wall is connected on one side, on the other side you have to connect your adsl modem in one and your telephone in another socket, Usually the sockets have descriptions on them specifing which decive should be connected to the socket.

Now you should have a dial up modem(56Kbps internal or external modem) connect this modem to the socket which specifies, Telephone. Configure the modem. configure yor fax settings to use this modem. Now you can send your faxes.

If your ISP does not support dial-up then you cannot use it to send faxes.
