:How much of a upgrade is required to go from Doc 1.0/1.1 to Doc 3.0, compared to Doc 2.0 to Doc 3.0? In other words, if a MSO has a network operating in Doc 2.0 and a network operating in Doc 1.0/1.1, which network are they more likely to upgrade first?
The upgrade to 3.0 REQUIRES that the Nodes be split since 3.0 bonding means that your modem is talking via more than one channel at the same time and thus there needs to be more Channels to support the same number of customers on the node (IOW: A 3.0 node running at 50Mbs can support less users than a 30Mbs node with 3 or so users per Channel so you must split the node to keep the concurrent bandwidth down). 1.x/2.0 allocates only one channel per user so even if more than one user is assigned the same channel, you can get more users on a node than with 3.0 (since a maxed out channel will not affect the users on a different channel).
