Specifications

Latency
The time between initiating a request for data and the beginning of
the actual data transfer. Network latency is the delay introduced
when a packet is momentarily stored, analyzed and then forwarded.
Loading
The addition of inductance to a line in order to minimize amplitude
distortion. Used commonly on public telephone lines to improve
voice quality, it can make the lines impassable to high speed data,
and baseband modems.
Loopback
A type of diagnostic test in which the transmitted signal is returned
to the sending device after passing through all or part of a
communications link or network.
Manager
An application that receives Simple Network Management Protocol
(SNMP) information from an agent. An agent and manager share a
database of information, called the Management Information Base
(MIB). An agent can use a message called a traps-PDU to send
unsolicited information to the manager. A manager that uses the
RADview MIB can query the RAD device, set parameters, sound
alarms when certain conditions appear, and perform other
administrative tasks.
Multimode Fiber
A fiber with a large core diameter; 50-200 microns compared with
the wavelength of light. It therefore propagates more than one
mode. With multimode fiber, light traverses multiple paths, some
longer than others. This leads to dispersion, which reduces optical
range.
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.
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.
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.
