10BASE-T Stackable Hubs
When connecting a transceiver to the hub, the transceiver's SQE (heartbeat)
function should be disabled.
Multilevel Cascading
Hubs can be cascaded in multiple levels, provided no path between stations
on the network goes through more than four repeaters. For example, a
backbone level of hubs can be connected in a bus using 10BASE2 cabling,
and second-level workgroup hubs can be connected to the backbone hubs
using twisted-pair cabling. This type of network layout allows a greatly
expanded number of network nodes without sacrificing manageability.
