Specifications

Jitter
The deviation of a transmission signal in time or phase. It can
introduce errors and loss of synchronization in high speed
synchronous communications.
Laser
A device that transmits an extremely narrow and coherent beam of
electromagnetic energy in the visible light spectrum. Used as a light
source for fiber optic transmission (generally more expensive, shorter
lived, single mode only, for greater distances than LED).
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.
Master Clock
The source of timing signals (or the signals themselves) that all
network stations use for synchronization.
Modular
Modular interfaces enable field-changeable conversion.
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.
Parity Bit
An additional non-information bit added to a group of bits to ensure
that the total number of 1 bits in the character is even or odd.
