TB7300 Installation and Operation Manual Glossary 61© Tait Limited November 2017GlossaryThis glossary contains an alphabetical list of terms and abbreviations foundin this document, related to the TaitNet network and the TB7300 basestation.AMBE+2™ Advanced Multiband Excitation. A voice compression technology patentedby Digital Voice Systems, Inc and used in the vocoders of DMR radios.base station A radio receiver and transmitter that is located in a specific place (at a site)that enables a two-way radio to communicate with a dispatcher or over alarger range with other two-way radios.call A complete exchange of information between two or more parties. A callrequires a receive signal path and a transmit signal path. In conventionalsystems, a call is an over, but in trunked systems, a call may be aconversation, made up of a number of overs.channel 1. A path through which signals can flow.2. In the RF domain, a frequency pair (or just a single frequency in asimplex system). Also called a physical channel in this manual.3. One of the two timeslots that DMR provides for each radio frequency(physical channel). Refer to “logical channel”.4. A set of configuration information that defines the frequency pair andother related settings (a channel configuration). “Channel” has thismeaning in the web interface.channel spacing The bandwidth that a channel nominally occupies. If a base station has achannel spacing of 12.5 kHz, there must be a separation of at least 12.5 kHzbetween its operating frequencies and those of any other equipment.channel table The base station’s database of channel configurations.configuration file Consists of all the configuration settings needed for a base station, storedas a file.conventionalnetwork Systems that do not have centralized management of channel access.System operation is entirely controlled by system end users.CTCSS CTCSS (continuous tone controlled squelch system), also known as PL(private line), is a type of signaling that uses subaudible tones to segregategroups of users.
