Editing Medium Attachment Unit (section)

===Functional specifications===
* Transmit function – the ability to transmit serial data bit streams on the baseband medium from the local [[Data terminal equipment|DTE]] entity and to one or more remote DTE entities on the same network.
* Receive function – the ability to receive serial data bit streams over the baseband medium.
* Collision Presence function – the ability to detect the presence of two or more stations' concurrent transmissions.
* Monitor function (optional) – the ability to inhibit the normal transmit data stream to the medium at the same time the normal receive function and collision presence function remain operational.
* [[Jabber (networking)|Jabber]] function – the ability to automatically interrupt the transmit function and inhibit an abnormally long output data stream. It removes equipment from the network whenever it continuously transmits for periods significantly longer than required for a maximum-length packet, indicating a possible problem with the [[Network interface controller|NIC]].
