Actually, to make it all clear, he was talking about RADSL (Rate Adaptive
DSL), which at longer loops will connect below the maximum rate of 1/7
Mb. Your customer wants something like 2Mb uplink/10Mb downlink, so you
have to install 2 lines, that you must bond/balance/equalize so that you
get the required bandwith. You were reffering to the connection to the CO
as overloaded, but actually most of us have single mode fiber at 155Mb per
chassis, so I doubt it will become overload just because we are
provisioning two circuits to the same client.
Now, to answer the question that started the thread, you wil probably want
something like teql on linux, or similar. This depends a lot on your
service platform, so you'll have to provide more details so I can give you
a precise answer.
