I think your missing the point im trying to get across here. The equipment in the UBR conforms to DOCSIS standards and is therefore up to date. The problem with the UBR mentioned is that it is over-subscribed. A UBR has a finite resource of bandwith which it shares between its users and if there are too many people connected to that UBR the bandwith available is not sufficient for all the users to download/upload at the same time and this is the reason there are problems. Installing newer kit in the UBR would not solve the problem it needs additional equipment installed that will effectively re-segment the UBR. A new DOCSIS line card would not make any difference if it still had the same amount of users to serve so the way VM could fix the issue is by installing additional equipment.

I dont think its fair to say VM are running on knackered old equipment as this isnt the case. Sure the equipment may be a few years old but it still conforms to the standards that operate on the network so its age is irrelevant as any new kit would be run on the same protocols as the exsisting stuff.
