| + | ===== Medium Dependent Interfaces (MDI) ===== | ||
| + | To communicate in a compatible manner, all stations shall | ||
| + | adhere rigidly to the exact specification of physical media signals defined in the appropriate clauses | ||
| + | in this standard, and to the procedures that define correct behavior of a station. The medium-independent | ||
| + | aspects of the LLC sublayer and the MAC sublayer should not be taken as detracting from | ||
| + | this point; communication in an Ethernet Local Area Network requires complete compatibility at the | ||
| + | Physical Medium interface (that is, the physical cable interface). | ||

| + | ===== Attachment Unit Interface (AUI) ===== | ||
| + | Some DTEs are located some distance from their connection to the | ||
| + | physical cable. A small amount of circuitry will exist in the Medium Attachment Unit (MAU) | ||
| + | directly adjacent to the physical cable, while the majority of the hardware and all of the software will | ||
| + | be placed within the DTE. The AUI is defined as a second compatibility interface. While conformance with | ||
| + | this interface is not strictly necessary to ensure communication, | ||
| + | since it allows maximum flexibility in intermixing MAUs and DTEs. The AUI may be optional or | ||
| + | not specified for some implementations of this standard that are expected to be connected directly to | ||
| + | the medium and so do not use a separate MAU or its interconnecting AUI cable. The PLS and PMA | ||
| + | are then part of a single unit, and no explicit AUI implementation is required. | ||
