network region
A group of IP endpoints and switch IP interfaces that are interconnected by an IP network. IP interconnection is used
because IP interconnection is less expensive or provides better performance than interconnections between members of
different regions.

node
A switching point or a control point for a network. Nodes are either tandem or terminal. Tandem nodes receive signals
and pass the signals on. Terminal nodes originate a transmission path or terminate a transmission path.
nonfacility-associated signaling (NFAS)
A method of signaling in which multiple T1 facilities, multiple E1 facilities, or both share a single D-channel to form an
ISDN-PRI. If D-channel backup is not used, one facility is configured with a D-channel. The other facilities that share the
D-channel are configured without D-channels. If D-channel backup is used, two facilities are configured with D-
channels, with one D-channel on each facility. The other facilities that share the D-channels are configured without D-
channels.
