LAN
Local Area Network. A computer network that interconnects computers in
a limited area, such as a single building or group of buildings.
LED
Light Emitting Diode. Also the screen representation of a physical LED.
license
Some operational functions of the base station are controlled by licenses.
Purchasing a license from Tait allows you to enable the feature set which
includes the required functionality.
logical channel
One of the two timeslots provided in each TB7300 radio frequency. Each
timeslot can function as a separate logical channel, independent of the other
timeslot. One radio frequency can therefore carry two separate voice or
data streams, one in each timeslot.
mobile station
The term used in the ETSI DMR standard documents for a two-way radio
(generally a mobile or a portable radio) conforming to the DMR
specifications.
MS
Mobile Station (see above).
NAT
Network Address Translation allows the use of a single IP address for a
whole network of computers. A NAT sits between the public Internet and
the network it serves, and works by rewriting IP addresses and port
numbers in IP headers on the fly so the packets all appear to be coming
from (or going to) the single public IP address of the NAT device instead
of the actual source or destination.
network element
Any device that is network-connected. A TaitNet digital network consists
of a number of network elements. The TB7300 base station is a network
element designed and manufactured by Tait.
NTP
Network Time Protocol is a protocol and software implementation for
synchronizing the clocks of computer systems across a network. An NTP
server obtains the correct time from a time source and sets the local time in
each connected computer.
octet
A set of 8 bits.
Offline mode
A mode of operation in which active service is suspended so that special
operations can be carried out, such as programming in a new configuration
or carrying out certain diagnostic tests.
Online mode
The normal operating mode of the base station.
