Value Added Network
VAN
A communication network that provides features other than

business object models encapsulate the data and behaviors that are
used by object views. Object views send messages to the
encapsulated objects to effect any required updates or to create
new object instances.
Narrowband. A low-capacity
communications Circuit/path. It usually implies a speed of 56Kbps
or less. (Contrast with Wideband
and
Broadband)
Voice Mail
An automatic answering service with the ability to record a
message. Unlike simple answering machines, Voice mail uses a
