This list is not exhaustive, and for those that are shown, other combinations are usually possible. This technology is proprietary to Hewlett Packard. The wiring distance is CAG 3 cable to 100 meters, CAG 5 UTP 150 meters. However, it is recommended you use the same standards as 10BaseT for NEW wiring. Also, there is no Token monopolization problem like Token Ring has.
Hubs have a heirarchial topology, with a root hub, that can branch three deep in the heirarchy.
For CAG 3 cable, the maximum network diameter is 600 meters, and 900 meters for CAG 5. The following are a collection of various network types. For example, MCI uses ATM for its long-haul backbone delivery. Probably, ATM will be the broadband ISDN carrier method. Because rates from 25 up to 622 MBS are defined for the desktop, a LAN and WAN can be integrated into the same thing.
