I anticipate that ntl expect each cable modem to have it's own direct connection to the cable coming from the street cabinet. If you were to have two cable modems there would thus need to be two cables from the cabinet to the house, no doubt something that ntl would not normally do.

With the current STB and CM arrangement, no doubt the street cable is split at the intake to the house. No doubt some tech will explain why this split cable can't be made to work with two CMs instead of the CM / STB arrangement currently present.
