Expanding beyond the narrow "provisioning" term, maybe to help illustrate the who and the whom.

The BES, in my case, is talking to srp.ca.blackberry.net, which is rim, not carrier, infrastructure. It was this infrastructure that was NOT seeing any traffic from my carrier.

In the ISO standard seven-layer Open Systems Interconnect (OSI) reference model, OSI Model: Definition and additional resources from ZDNet, the carrier and the device's chipset performs layers 1 through 3, RIM infrastructure performs layers 3 and 4, and the end points (BES and the DEVICE applets) perform layers 6 and 7.

I once had (but cannot re-find to include here) a link that showed this as well as positioning GSM and CDMA in the model.
