2900 Series with an EHWIC-VA-DSL-A. Configuration Issues?

Hi to all, I hope that you can help with the next scenario:

I need to configure an EHWIC VDSL/ADSLoPOTS interface card in a 2921 router to link to the ISP which service is an ADSL line with downlink 10 Mbps and uplink 2 Mbps but many questions have arisen, which are:

1. How should I connect the 2921?

Since the EHWIC has only one RJ-11 port, the modem is Zhone 6211I3302 with standards ports Line(RJ-11) Phone(RJ-11) USB and LAN(RJ-45). I'm thinking avoid the modem and make a straight connection to the wall's jack through RJ-11 Straight Cable (or should I use RJ-11 Cross Over Cable?). If I cannot avoid the modem, it's obviously that I'll need an Adaptated RJ-45 to RJ-11 Cable; am I correct?

2. When I type show version appears:

     2 DSL Controllers.

     2 Ethernet Interfaces

     3 Gigabit Ethernet Interfaces (These I know are the physical interfaces the router has).

     2 ATM Interfaces.

     1 Terminal line.

Which is the interface that I'm supposed to configure? Is it a controller configurable?.

I think the 2 DSL Controllers and the 2 Ethernet Interfaces are bounded one one (or is it the 2 DSL Controllers and the 2 ATM Interfaces, but this last it doesn't make sense to me).

3. What protocol should I configure PPP or PPPoE?

I think I should configure PPPoE in the physical interface (when you tell me which one or if can figure it out).

4. How do I configure a logical interface?

I thank you to all of you for taking the time to read this and I'll be very grateful for any help that you can give me.

Hi there,
From the iPad is always more difficult to answer because I don't see the post anymore :( but for what I remember these are the answers:

a) you can and definitely have to skip the modem (better design and performance) . This could lead you to ask to your ISP the settings required
b) every controller is configurable but you need to configure an ATM interface and not a controller
c) a logical interface is an interface that physically does not exist. Loopback and subinterface(you are gonna need one) are an example along with svi,bvi and a couple more.

d)you generally need to configure ppp but since this adsl service is a point to point connection, it does matter how the ISP configured its side and if password are involved in it (chap or pap authentication). I hope the examples below will help you to figure out the final config.

Thank you Alessio. I really appreciate your time, the tons of material to study and guidance that showed me the possible way to a successful configuration. As soon as I get the working configuration, I'll post the result. Nevertheless, if I got stuck I'll claim for help.

Greetings.
