capable interface device.
IP
internet protocol. A protocol which provides for transmitting blocks of data
between hosts identified by fixed-length addresses.
ISDN
integrated services digital network. A network architecture that enables end-to-
end digital connections. The network supports diverse services through inte-
grated access arrangements and defines a limited set of standard, multipurpose
interfaces for equipment vendors, network providers, and customers. Inter-
working with a public switched telephone network is retained.
local area network (LAN)

connect information processing equipment in a limited geographic area.
MIB

tion used by SNMP.
out-of-band
Signaling that is separated from the channel carrying information (voice, data,
video, etc.). Typically the separation is accomplished by a filter. The signaling
includes dialing and other supervisory signals.
packet
A message containing both control information and data. The control informa-
tion is used for routing the packet through a network to its final destination.
Contrast with frame relay frame.
packet-switching network
A telecommunications network based on packet-switching technology, wherein
a transmission channel is occupied only for the duration of the transmission of
the packet. Contrast with frame relay network.
parameter
A numerical code that controls an aspect of terminal and/or network operation.
Parameters control such aspects as page size, data transmission speed, and tim-
ing options.
