wide area network (WAN)
assigned to echo servers, time servers, remote login (TELNET) servers, and file
transfer (FTP) servers.
wide area network (WAN). A network that operates over a larger geographical area than a
local area network (LAN)—typically, an area with a radius greater than one kilometer.
The elements of a WAN may be separated by distances great enough to require
telephone communications. Contrast with local area network (LAN).
wide area network (WAN) subsystem. The Subsystem Control Facility (SCF) subsystem
for configuration and management of WAN objects in G-series RVUs.
wild-card character. A character that stands for any possible character(s) in a search string
or in a name applying to multiple objects. In DSM object-name templates, two wild-card
characters can appear: ? for a single character and * for zero, one, or more
consecutive characters. See also object-name template.
X.25. The CCITT standard protocol for transport-level network service. Originally designed
to connect terminals to computers, X.25 provides a reliable stream transmission
service that can support remote login.
X.25 Access Method. See X25AM.
X25AM (X.25 Access Method). An HP product that implements, for WANs, the services of
the Network Layer and layers below.
X.25 network. Any network or subnetwork linked using X.25 standards. X.25 standards are
CCITT standards that define packet switching carrier communication in the Network
Layer over wide area networks (WANs). See also International Telecommunications
Union Telecommunications (ITU-T) and packet switching.
$ZZLAN. See LAN manager (LANMAN) process.
$ZZWAN. See WAN manager process.
