Page 11: Design Notes
DESIGN NOTES The Tron AIS TR-2600, an AIS Base Station, is the most basic AIS-related entity of any AIS Shore Infrastructure. The AIS Base Station is defined by IMO. It cannot operate on its own, because it needs commands from an external unit, i.e. a Base Station Controller (BSC), which may be connected to a Management System. -
Page 12: Message 16 - Assigned Mode
• Each time a new rate is determined, the last start slot is used to allocate the other slots in the frame. Old reserved slots are marked free. • Each time a CAB message is received enabling or disabling one of the channels, the current start slot will be used to calculate the other slots according to schedule. -

• BSC IP address and destination port for UDP connection 1.2.9.2 Configurable start of msg 4 In the Jotron AIS BS there are three options at a system re-start for how to handle msg.4. Normally the msg. 4 is defined in the CBM message, with a start slot. -
