Glossary
Authentication—
A method of identifying a caller before accepting a call. The
Pipeline supports token card authentication, as well as standard password, and
encrypted password authentication. (Encryption is a method of encoding and
decoding data.)
Bandwidth—
The amount of information that can flow through a line, measured
in bits per second
Bridging—
One method the Pipeline can use to move data between your network
and a remote network. Bridging makes remote networks look like one large
network.
Channelized versus nailed—
A connection can use multiple channels of
available bandwidth, as in ISDN, which provides two B channels, one or two of
which can be used for the same call, or you can have a permanently connected,
fixed amount of bandwidth in a nailed connection.
Clearing a call—
Hanging up the call gracefully. A call usually involves a
number of switches. Clearing a call shuts down all the connections end to end.
Compression—
A method of reducing the size of data to increase performance.
Some algorithms maximize speed, some maximize data compression. The
compress is software must be present on both ends of a connection to be used.
Dynamic Bandwidth Allocation (DBA)—
A proprietary method (developed
by Ascend) to add or subtract B channels as needed to make the most efficient
use of connection resources.
