In the case of 10/100/1000BASE-T, having only two transceivers connected
by a proper cable is the ONLY way to connect them. Unlike
10BASE2/10BASE5 (coaxial Ethernet), you cannot have more than two
transceivers connected to a given cable.
Whether those two transceivers comprise the entire collision domain or
only a portion of it is a function of the hub device (bridge/switch vs.
repeater). Remember, the hub device has an internal transceiver for each
port, and all 10/100/1000BASE-T configurations use only point-to-point
links between pairs of transceivers.
