Presently i am working in ISP, and we are providing internet access via simple dialup, ISDN and IVS. and now we want to implement DSL i ve talk with few peoples regarding whether to use ATM or MPLS in DSL implementation but because they are solution providers so i think they are giving me expensive solution. as long as i know about this is,whole world is shifting from ATM to MPLS Technology. ATM implementation cost is very high. so i need suggestion from u because you also have practical exposure.
