license Some operational functions of the base station are controlled by licenses.
Purchasing a license from Ta it allows you to enable the feature set which
includes the required functionality.
LSM Linear Simulcast Modulation is a proprietary modulation scheme designed
to give optimal performance in simulcast systems, compared to that
obtainable using C4FM.
M
marshalling
duration
The length of time that the voice stream needs to travel from the central
voter to the furthest channel group member. The fixed marshalling duration
parameter includes the time needed to fill the transmit buffer to the required
level.
master The channel group master is the member with the control connection to
the trunking site controller.
multicast group The group of hosts associated with a specific IP multicast address.
multicast IP address An IP address that refers to a group of hosts rather than a single host. These
hosts will all accept packets with this IP address.
mute Prevents audio from being passed to the radio’s speaker.
N
NAC Network Access Code. The 12 most significant bits of the network identifier
information that precedes every packet sent on the CAI. The NAC
identifies which network the data belongs to, allowing base stations and
mobiles to ignore packets belonging to interfering networks.
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 TB9400 base station is a network
element designed and manufactured by Tait.
