The Digital Selective Calling (DSC) system is one of the
essential elements of the GMDSS, the automated digital
communication system developed by the International
Maritime Organisation (IMO) to enhance navigational
safety. The DSC system can also be used to quickly
and efficiently establish routine communications with
other ships and coast stations that are DSC equipped.
The DSC-6/6A both consist of a combined encoder and
decoder for generating and receiving digital selective
calls. When used in conjunction with a FURUNO MF/HF
transmitter/receiver they provide full automatic control of
transmit and receive frequency, class of emission, and
other parameters as entered from the front panel or
contained in the telecommand information in an
incoming call. They also allow scanning of distress or
routine DSC frequencies via an appropriate FURUNO
receiver.
In an emergency the DSC-6/6A transmits a distress alert
via the radio equipment five seconds after pressing the
[DISTRESS] button. When the DSC Watch Receiver
AA-50 is connected, the DSC-6 processes the
messages received on the MF/HF DSC distress and
safety frequencies.
The DSC-6A incorporates an independent receiver
which keeps a continuous watch on MF DSC frequency
2187.5 kHz.
