Re: Broadband Subscriber Management

[Curtis Maurand <cmaurand () xyonet com>]

I don't understand why DSL providers don't just administratively down 
the port the customer is hooked to rather than using PPPoE which costs 
bandwidth and has huge management overhead when you have to disconnect a 
customer.  I made the same recommendation to the St. Maarten (Dutch) 
phone company several years ago.  They weren't listening either.   That 
way you can rate limit via ATM or by throttling the port administratively.

Just a suggestion
