X25AM (X.25 Access Method). A NonStop 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 Internet
and packet switching.
$ZZLAN. See LAN manager (LANMAN) process.
$ZZWAN. See WAN manager process.
