Codec Conversion
The back-to-back transfer of an analog signal from one codec
into another codec in order to convert from one proprietary coding scheme to
another. The analog signal, instead of being displayed to a monitor, is delivered
to the dissimilar codec where it is redigitized, compressed and passed to the
receiving end. This is obviously a bi-directional process. Conversion service
is offered by carriers such as AT&T, MCI and Sprint.
Collapsed
Backbone
Network architecture under which the backplane of a device such as a hub performs
the function of a network backbone; the backplane
routes traffic between desktop nodes and between other hubs
serving multiple LANs.
COM

Communications Server
Also called an asynchronous server or asynchronous

Connection-Oriented [Service]
Connectionless communications/network
A form of cell switching or packet multiplexing
that identifies individual channels based on global addresses rather than predefined
virtual circuits. Packets are transferred from source
to destination without the need of a pre-established connection. Examples are
IP and SMDS (see also
datagram). Used by shared-media LANs
like FDDI and token ring.
