(OK, let's see if this one gets through to the list...)
Asynchronous CIRs are offered by some carriers but not all of them. It just
means that you can get two different CIRs on the same PVC - one upstream, one
downstream (however you want to define upstream and downstream :-)
So if you have a lot of traffic going from your central site to remote sites
(interactive, software downloads, whatever), but not much going the other way,
it may be more economical to have say a 256Kbps CIR from the central site out to
a remote site, but only 128Kbps from the remote site to the central site (using
the same PVC).
