You understand wrong.

Bandwith on demand is a *CONCEPT*. We do bandwith on demand.

Ascend *also* does bandwith on demand.

Ascend does it with what they call MP+. *THAT* is proprietary to Ascend
and we do not support it. But we *do* do bandwith on demand, we just
do it with a different system.

There is no standard to do it at this time, that is being developed and
is calledf Bandwith Allocation Control Protocol, or BACP.

*sigh* Ascends do not require MP+ support on the other end to do bandwith
on demand, it is only required for some of the more advanced aspects that
are particular to Ascends. They can still do bandwith on demand without
the other end doing MP+ - which is how they work with every other box.
People are doing bandwith on demand *today* from Ascend boxes to the 5BRI
cards in PM-2 chassis.

If you absolutely must have MP+, have fun, you are stuck with Ascend and
they can charge you for the privilege of using a non-standard protocol
which will be moot when BACP is finalized.
