Actually the NATS data network is an MPLS based cloud no point to point circuits. The core bearers are 100mb and the tail circuits run to the local POP. A 2mb MPLS circuit is around £4.5k, the core network is where the real costs are. But that is already being paid for on current levels.
I would question the need for a such a big circuit for local access to a data stream. More in the region of 512k to 1mb.
But what would I know.
