DEFINITIONS

CSMA/CD

Carrier Sense Multiple Access with Collision Detection.

1000BASE-T

IEEE 802.3-1998 Physical Layer specification for 1000 Mb/s

CSMA/CD LAN using four pairs of Category 5 balanced copper

cabling.

1000BASE-SX

IEEE 802.3-1998 using short wavelength laser devices over

multimode fiber

1000BASE-LX

IEEE 802.3-1998 using long wavelength laser devices over

multimode and single-mode fiber.

Auto-Negotiation

The algorithm that allows two devices at either end of a link

segment to negotiate common data service functions.

Base Page

The first 16-bit message exchanged during IEEE 802.3-1998

Auto-Negotiation.

Comma

The seven-bit sequence that is part of an 8B/10B code-group

that is used for the purpose of code-group alignment.

Comma-

The seven-bit sequence (1100000) of an encoded data

stream.

Comma+

The seven-bit sequence (0011111) of an encoded data stream.

Data Frame

Consists of Destination Address, Source Address, Length

Field, logical link control (LLC) Data, PAD, and Frame Check

Sequence.

DTE

Any source or destination of data connected to the local area

network.

EOF

End of frame.

EOP

End of packet

Even Parity

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 1 so

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

number.

Frame

Same as Data Frame

Full Duplex

A mode of operation that supports simultaneous

communication between a pair of stations, provided that the

Physical Layer is capable of supporting simultaneous

transmission and reception without interference.

GMII

Gigabit Media Independent Interface.

IPG

Inter-Packet Gap (IPG): A delay or time gap between

CSMA/CD physical packets intended to provided interframe

recovery time for other CSMA/CD sublayers and for the

Physical Medium.

MIB

Management Information Base (MIB): A repository of

information to describe the operation of specific network

device.
