Specifications

Multiplexer
At one end of a communications link, a device that combines
several lower speed transmission channels into a single high speed
channel. A multiplexer at the other end reverses the process.
Sometimes called a mux. See Bit Interleaving/Multiplexing.
Network
(1) An interconnected group of nodes. (2) A series of points,
nodes, or stations connected by communications channels; the
collection of equipment through which connections are made
between data stations.
Node
A point of interconnection to a network.
Packet
An ordered group of data and control signals transmitted through
a network, as a subset of a larger message.
parameters
Parameters are often called arguments, and the two words are
used interchangeably. However, some computer languages such as
C define argument to mean actual parameter (i.e., the value), and
parameter to mean formal parameter. In RAD CLI, parameter
means formal parameter, not value.
Payload
The 48-byte segment of the ATM cell containing user data. Any
adaptation of user data via the AAL will take place within the
payload.
Physical Layer
Layer 1 of the OSI model. The layer concerned with electrical,
mechanical, and handshaking procedures over the interface
connecting a device to the transmission medium.
Port
The physical interface to a computer or multiplexer, for connection
of terminals and modems.
prompt
One or more characters in a command line interface to indicate
that the computer is ready to accept typed input.
Protocol
A formal set of conventions governing the formatting and relative
timing of message exchange between two communicating
systems.
Pseudowire
Point-to-point connections set up to emulate (typically Layer 2)
native services like ATM, Frame Relay, Ethernet, TDM, or
SONET/SDH over an underlying common packet-switched network
(Ethernet, MPLS or IP) core. Pseudowires are defined by the IETF
PWE3 (pseudowire emulation edge-to-edge) working group.
Register
A storage device capable of receiving and holding a number of
digits.
Repeater
A device which automatically amplifies, restores or reshapes
signals to compensate for distortion and/or attenuation prior to
retransmission.
Serial Transmission
A common mode of transmission, where the character bits are
sent sequentially one at a time instead of in parallel.
