I recently had a DSL line activated, the DSL provider wanted me to pay 100 for installation, so I figured what the hell, I'll do it myself and
save some money.  Anyways,  the installation kit came with four DSL filters that you plug into the R11 phone plug.  So here is my question(s):
Do you have to have a dsl modem for the service to connect, I thought that the router could connect directly to the DSL isp using the PPPoE feature.  I have a linksys WET11, I configure it to use PPPoE and set the username and password, then I try to connect and I get a message saying that it failed to connect to server.  Well here is the problem the input wan connection to the WET11 is a RJ45, I trying to run a RJ11 into it by connecting the appropriate pins transmit/receive.  I have read that DSL has uses one pin for receive and one for transmit.  So I tried to connecting one of the transmit wire to a spliced rj45 transmit pin, and the same for receive end.  Only two wires connected. Can I do this or not, or do I have to have a DSL modem first or do the other pair of transmit/receive on the RJ45 have to be connect also???  I would appreciate someone explaining a little about the basics of DSL and if I'm do this right or totally wrong.  I have been a cable broadband costumer, so I'm ignorant to dsl.  thanks.

Hi. Another beginner here but I will share what I know. Not all Routers have the ability to act as a "DSL modem". As an example, I have a 2Wire 100w Router but I still need my Westell DSL Modem to connect to my DSL service. My Westell Modem acts as a mini DHCP server and NAT provider in that the Modem assigns my PC an IP address. I would double check the spec on your router to make sure it can perform as a "DSL Modem" and DHCP provider.

1) DSL and ADSL services require a modem connected to the phone line.

2) The modems are connected via a filter that "separates" normal phone line activities from the
data signal , in effect doing a split of the line into a modem branch and a phone branch.

3) The modem should have an ethernet interface that connects either directly to the network card
in your computer or to your router or router/switch assembly. The router needs to understand PPPoE
or similar when talking to the modem. DON'T get a modem with USB interface!

4) The "inside" of the router goes to your network or your computer.
