    There is a debate among our engineering staff as to the best means of
    provisioning broadband service over copper facilities. Due to our
    history, we have a mix out in the field. Some customers are on DSLAMS
    set up for bridged connections with DHCP; isolated by a variety of means
    including VLANS. Some customers are on PPPoE over ATM. Some customers
    are on PPPoE over ethernet (PPPoEoE ?? :) ).

    There seem to be pros and cons to both directions. Certainly true
    bridging has less overhead. But modern CPEs can minimize the impact of
    PPPoE. PPPoE allows for more flexible provisioning; including via
    RADIUS. Useful for the call center turning customers on/off without NOC
    help. But VLAN tricks can sometimes do many of the same things.

    Opinions on this? I'd be interested in hearing the latest real world
    experience for both and the direction most folks are going in.

    BTW, I doubt it is relevant to the discussion, but most of our DSLAMS
    are Adtran TA5000s (or are being migrated to that platform.) We are
    mostly a cisco shop for the upstream routers.

    Thanks,

    John
