Notes:

If we look at the intermediate network that could come from the cable-phone conflict the picture could brighten. That's why I talked about the cable problem or its opportunity! Several schemes are now available for sending Ethernet on cable. That's what cable guys should be doing. They need to be putting high bandwidth POPs at their head ends to enable multiple channels of Ethernet on their cable plants now. Subscribers will pay for that and suddenly we have a reasonable interim solution to the bandwidth problem. Cable can deliver Ethernet to a large number of users over existing cable. This scheme isn't fully symmetric but it can support more than ISDN even as a back channel. It will work for many workers at home and for schools and for many small businesses. Larger information providers will need 1.5 and 45 Mbit lines for servers.
