IEEE 802.3

A physical layer standard specifying a linear bus network LAN with a CSMA/

CD access method on a bus topology. Ethernet follows the 802.3 standard,

transmitting at 10 megabits per second. This is the most common local area

network specification. Physical variations of IEEE 802.3 include 10Base2 and

10BaseT.

in-band signalling

Signalling made up of tones which pass within the voice frequency band and

are carried along the same circuit as the talk path being established by the sig-

nals. Virtually all signalling (request for service, dialing, disconnect, etc.) in

the U.S. is in-band signalling. Most of that signalling is MF (Multi-Frequency)

dialing. The more modern form of signalling is out-of-band.

interexchange carrier

Since divestiture, any carrier registered with the FCC authorized to carry cus-

tomer transmissions between LATAs interstate, or if approved by a state pub-

lic utility commission, intrastate. Includes carriers such as AT&T

Communications, Satellite Business Systems, GTE Telenet, GTE Sprint, and

MCI.

information element

The name for the data fields within an ISDN Layer 3 message.

interworking

Communication between two types of networks or end equipment. This may

or may not involve a difference in signalling or protocol elements supported.

Internet Protocol

A TCP/IP protocol describing software that tracks the Internet address of

nodes, routes outgoing message, and recognizes incoming messages. Used in

gateways to connect networks at OSI network Level 3 and above.

IPX

Internetwork Packet Exchange. A Novell NetWare protocol used to move in-

formation across networks.

ISDN

Integrated Services Digital Network. A network architecture that enables end-

to-end digital connections. The network supports diverse services through in-

tegrated access arrangements and defines a limited set of standard, multipur-

pose interfaces for equipment vendors, network providers, and customers.

Interworking with a public switched telephone network is retained.

jabber

An error condition in which a network device continually transmits garbage

onto the network. In IEEE 802.3, a data packet whose length exceeds that pre-

scribed in the standard.
