Maritime identification digits are used by radio communication facilities to identify their home country or base area in digital selective calling (DSC), Automatic Transmitter Identification System (ATIS), and Automatic identification system (AIS) messages as part of their Maritime Mobile Service Identities.
The Antenna Interface Standards Group (commonly referred to as AISG) is a non-profit international consortium formed by collaboration between communication infrastructure manufacturers and network operators with the purpose of maintaining and developing a standard for digital remote control and monitoring of antenna line devices in the wireless industry.
