Whether ethernet or ATM is used between CPE and DSLAM ?

Answer:ATM mode data transfer will happen between CPE and DSLAM(ASAM,ESAM & IP DSLAM)

How PPPoE / PPPoA is used between CPE and DSLAM?

Answer: Depends what type of DSLAM you are using.
For example,DSLAM is ATM based then we need to configure the CPE in PPPoA mode.IF DSLAM is Ethernet based then we need to configure the CPE in PPPoE mode

What are the protocol used between the CPE and DSLAM?

Answer:Depends on what application that you use.

Remaining thing I don't have idea.
