(sometimes abbreviated "thruput" class) reflects the line speed in bits per second.
is a MAC (see that entry) technique for data transmission that uses a "ring" configu-
ration of stations, and a "token" that is passed around the ring until taken by a station,
which inserts a packet, then retransmits the token.
is an integral (to an FRX8000 or N74/7500 node) SNA or BSC Interactive PAD con-
nected to a terminal.
is an internodal link. Trunks are necessary between nodes to maintain network con-
currency, by transmitting among nodes any configuration and routing updates, alarm
messages, etc.
is anything connected to the network that is, itself, not part of the network.
is a CCITT standard defining a physical and electrical interface that is typically used
by high-speed digital carriers.
is an independent logical path between two subscribers of a packet switching network,
established for the purpose of exchanging data.
is a CCITT recommendation that defines the service provided by an asynchronous
PAD to connect a character-mode terminal to an X.25 network.
is a CCITT recommendation that specifies the DTE/DCE interface for "packet mode"
operation in public data networks.
is a CCITT recommendation that defines the DTE/DCE interface for a character-mode
terminal accessing the PAD function in a public data network in the same country.
