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.
To limit the number of wires required between two involved in exchanging voice calls, a system was built in which multiple DS0s are multiplexed together on higher capacity circuits. In this system, twenty-four (24) DS0s are multiplexed into a DS1 signal. Twenty-eight (28) DS1s are multiplexed into a DS3.
