[cisco-nas] DSL info

[Aaron Leonard]

Hi John,

The typical DSL aggregation scenario involves using ATM rather
than Frame Relay from the DSLAM to the aggregation router.

It would typically be up to you rather than the telco, I think, to decide 
which encapsulation method is to be used between the CPE and
your aggregation router - PPPoA, PPPoE or RBE (RFC-1483 bridging.)

This gives you an overview.  As far as what aggregation router
to use ... I suppose if your 5350s have spare CPU and memory,
they could be used ... assuming that their software supports
the DSL aggregation feature you want (I don't know offhand.)

(this looks like more CPE-side stuff)

There must be some stuff on CCO that puts this all together with
AAA but I'm not finding it right now.  (I don't actually cover DSL myself.)

Regards,

Aaron
