wide area network (WAN) subsystem
wide area network (WAN) subsystem. The Subsystem Control Facility (SCF) subsystem
for configuration and management of WAN objects in G-series release version updates
(RVUs).
wild-card character. A character that stands for any possible character or characters in a
search string or in a name applying to multiple objects. In Subsystem Control Facility
(SCF) object-name templates, two wild-card characters can appear: ? (question mark)
for a single character and * (asterisk) for zero or more consecutive characters. See
also object-name template.
Windows Internet Name Service (WINS). A name resolution service that resolves
Windows NT networking computer names to Internet protocol (IP) addresses in a
routed environment. A WINS server handles name registration, queries, and release
version updates (RVUs). See also IP address.
WINS. See Windows Internet Name Service (WINS).
work files. Temporary files created during system generation that serve as storage areas.
Work files are useful for debugging purposes after system generation. You can choose
to make specified work files permanent.
working directory. In the Open System Services (OSS) environment, a directory,
associated with a process, that is used in pathname resolution for relative pathnames.
WORM. See write once, read many (WORM).
wormhole routing. A technique for reducing network latency in a router. Packet bytes are
immediately switched to the appropriate output port as soon as they arrive, rather than
accumulated in a buffer until an entire packet has been received. Contrast with store
and forward routing.
write once, read many (WORM). A media storage class in which data, once written, cannot
be erased or overwritten.
wye. A polyphase electrical supply where the conductors of the source transformer are
connected to the terminals in a physical arrangement that resembles the letter Y. Each
point of the Y represents the connection for a conductor at high potential. The angle of
phase displacement between each point on the Y is 120 degrees. The center point of
the Y is the common return point for the neutral conductor.
wye-delta. The interconnections between a wye source and a delta load.
X.21. A digital signaling interface recommended by the International Telecommunications
Union, Telecommunication Standardization Sector (ITU-T) that includes specifications
for data terminal equipment/data communications equipment (DTE/DCE) physical
interface elements, alignment of call control characters and error checking, elements of
the call control phase for circuit switched services, data transfer at or below 9600
bits/second, and test loops.
