Title: DSL Network Architectures and Services

Abstract: This talk will cover basic DSL network architectures and services, discussing the pros and cons of various DSLAM features to implement various network services. In particular, the talk will cover both wholesale and retail models of DSL services and how DSLAM features can be used to support these services. The DSLAM feature sets discussed will be (1) pure ATM switching, (2) Ethernet-based multiplexing, (3) IP-enabled multiplexing.
