Media Access Control (MAC): The data link sublayer that is

responsible for transferring data to and from the Physical

Layer.

Media independent Interface (MII): A transparent signal

interface at the bottom of the Reconciliation sublayer.

General class of pages optionally transmitted by Auto-

Negotiation able devices following the base page word

negotiation.

A group of four data bits. The unit of exchange on the MII.

The logical unit of data transferred across the POS-PHY Level

3 interface. This generally corresponds to the Data Frame as

defined previously, although the CRC may or may not be

present in the POS-PHY Level 3 egress direction.

Consists of a Data Frame as defined previously, preceded by

the Preamble and the Start Frame Delimiter, encoded, as

appropriate, for the Physical Layer (PHY) type.

SATURN compatible Packet over SONET interface

specification for physical layer devices. POS-PHY level 3

defines an interface for bit rates up to and including 2.488

Gbit/s.

Short hand notation for the POS-PHY Level 3 term.

The count of the number of 1’s in the data word of n bits. If

there are an odd number of 1s, then the parity bit will be a 0 so

that including the parity bit, the number of 1s are an odd

number

Start of Frame.
