[. . . ] Each user of the GMDSS is assigned a nine-digit number (MMSI ­ Maritime Mobile Service Identity) from the mobile maritime service. 3 digits of this number are used as a country code. On HF the system is working with 100 baud and a shift of 170 Hz. Selecting Options/Display offers the option of an ASCII or RAW bits display. The complex structures of the DSC are described in detail in the ITU-Rec. M. 493-11.

Part of the system is the DSC (Digital Selective Calling). Each user of the GMDSS is assigned a nine-digit number (MMSI ­ Maritime Mobile Service Identity) from the mobile maritime service. 3 digits of this number are used as a country code. On VHF the symbol rate is 1200 baud and the center frequency is 1700 Hz and the shift is 800 Hz. Selecting Options/Display offers the option of an ASCII or RAW bits display. The complex structures of the DSC are described in detail in the ITU-Rec. M. 493-11. GOLAY/GSC Parameter Frequency range Operation modes Modulation Symbol rate Receiver settings Input format(s) Value VHF Broadcast FEC FSK 300/600 Bd adaptive FM, BW = 15 kHz IF The GOLAY/GSC pager system originates in the USA and is based on the binary code found by Marcel GOLAY/GSC. The first standard defined only tone calling and could handle a maximum of 400, 000 addresses. After 1982 the system also allows for alphanumeric transmission and up to 4 million addresses may be selected via a coded preamble. 134 Transmission Modes WAVECOM Decoder W61PC/LAN Manual V7. 0 GOLAY Addressing Format This illustration shows the basic address format of the Golay Sequential Code (GSC). It is constructed from two code words which are derived using the Golay (23, 12) algorithm. The bit rate for each code word is 300 bit/s. Each received Golay word can contain up to three errors before integrity is compromised. To separate adjacent addresses, a separator word (comma) is transmitted at a rate of 600 bit/s. The message format is based on eight BCH (15, 7) code words that are grouped together to have exactly the same length as an address. Messages and addresses are thus easily interleaved. Each message block may contain up to 12 numeric or 8 alphanumeric characters.
