Para (41) : Subordinate or delegated legislation takes different forms. Subordinate legislation is. divided into two main classes, namely, (i) statutory rules, and (ii) bye-laws or regulations made (a). by authorities concerned with local government, and (b) by persons, societies, or corporations.
Ethernet Cat 5 cables have eight wires (four pairs), but under 10BaseT and 100BaseT standards (10 Mbps and 100 Mbps, respectively) only four (two pairs) of these wires are actually used. One pair is used for transmitting data and the other pair is used for receiving data.
So all of your devices on the HPNA (Coax) are shaing this bandwidth. Ethernet is dedicated bandwith at the link level, so if you had 4 STBs or other IP device connected directly to the RG each would have a 100Mbps connection available to the switching fabric.
