C is a multi-master bus, which means that multiple chips
can be connected to the same bus, and each one can act as a master by
initiating a data transfer. Used in the TB9300 for communications between
each reciter and its associated PA, and between reciter 1 and the PMU.
IP Internet Protocol is a protocol for sending data packets between hosts.
isolator A passive two-port device which transmits power in one direction, and
absorbs power in the other direction. It is used with a PA to prevent damage
to the RF circuitry from high reverse power.
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 TB9300 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.
