Air Link:
The portion of data transmission that takes place as a radio signal. The D-STAR air link includes both modulation methods and data packet construction.

The geographical region served by one D-STAR repeater.

Adding a user to the D-STAR registry.

A connection between just two devices, such as between two ID-1 transceivers.

A program that requests data (programs, Web pages, documents, etc.) from servers.

Code/Decode, a circuit or program that translates an analog signal to and from digital form, usually refers to an audio signal, such as voice or music. Different codecs, such as AMBE or MP3, have different rules for the translation between analog and digital.

The part of a D-STAR repeater that handles and routes the voice and data streams either between modules or between modules and the gateway.

DD (Digital Data):
The D-STAR high-speed digital data signal.

DV (Digital Voice):
The D-STAR digital voice + low-speed data signal.

( IRLP (Internet Relay Linking Project -, systems that allow repeaters to share digitized voice signals using Voice-Over-Internet Protocol (VOIP) technology.

To incorporate data packets from one protocol inside the data packets of another.

The set of protocols that control local area network (LAN) connections, described by the IEEE 802.3 standard.

Forward Error Correction, the process of adding information to data so that the receiver can correct errors caused by the transmission process.

The part of a D-STAR repeater that connects the controller to other gateways via the Internet.

Internet Protocol, the protocol that controls how data packets are exchanged on the Internet.

A D-STAR module is the part of a D-STAR repeater that implements voice or data communication over the air.

Capture the call sign of a received signal and post it to the system registry for other D-STAR repeaters to use for the purposes of routing calls.

A shared data base of authorized user call signs and gateways.

To direct data packets to specific destinations.

A computer that supplies data (programs, Web pages, documents, etc.) to clients when requested.

A group of D-STAR repeaters linked together and connected to other D-STAR systems by a single gateway.


From the Wikipedia (,
"In computing, a protocol is a convention or standard that controls or enables the connection, communication, and data transfer between two computing endpoints.” Essentially, protocols are the “rules of engagement” between two devices that allow them to connect to each other and exchange data. Protocols don’t guarantee that the data exchanged is correct or has meaning, they just describe how the data gets from one point to another. There are two D-STAR protocols; one for the air link that controls over-the-air transmissions and one that controls how information is exchanged between gateways. If you can create a radio or a program that plays by those rules, you can connect to the D-STAR world. Because D-STAR is an open protocol, all of the necessary information to play by those rules is publicly available.
