- Asynchronous Digital Subscriber Line
- An asymmetric high-speed digital
network connection, usually between a home or small business
and a telecommunications vendor, providing an always-up direct
connection to an Internet Service Provider
(ISP). The upstream (from the user to the ISP) and downstream
(from the ISP to the user) speeds are dissimilar, and usually
the latter is faster than the former. See also Digital Subscriber Line (DSL), Symmetric Digital Subscriber Line

handset, automatically ring the receiver's end for direct
connections, without the need to dial.
