Glossary
hop
a single trunk line between two switches in a frame relay network. An
established PVC consists of a certain number of hops, spanning the distance form
the ingress access interface to the egress access interface within the network.
host computer
The primary or controlling computer in a multiple computer operation.
in-band
Signaling (dialing, diagnostics, management, configuration, etc.) over the same
channel used for data.
ingress
Frame relay frames leaving from an access device in a direction toward the frame
relay network. Contrast with egress.
interface device
Provides the interface between the end device(s) and a frame relay network by
encapsulating the user's native protocol in frame relay frames and sending the
frames across the frame relay backbone. See also encapsulation and frame-relay-
capable interface device.
ISDN
Integrated Services Digital Network. A network architecture that enables end-to-
end digital connections. The network supports diverse services through
integrated access arrangements and defines a limited set of standard,
multipurpose interfaces for equipment vendors, network providers, and
customers. Interworking with a public switched telephone network is retained.
local area network (LAN)
A privately owned network that offers high-speed communications channels to
connect information processing equipment in a limited geographic area.
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.
