Bits of both depending what equipment you connect to. On the newer equipment, which you are connected to right now, speed is policed at the equipment you connect to and displayed on the modem which receives a configuration file and commands to add a service flow. The configuration file's bandwidth settings are not essential it could be totally policed by the VM kit.
On the older equipment downstream is policed by the equipment, upstream by the modem
but the parameters for both
can come from the config file - IE without the appropriate security it was possible to ram a config file into a modem and the network would allow the modem to operate at that speed. This is largely gone now.
You are on the newer kit so I'm sorry to say when you get a speed change there is nothing you can do to avoid it
