INTERFACING THE AUTOMATED MARITIME MOBILE TELEPHONE SYSTEM WITH THE U.S. PUBLIC SWITCHED TELEPHONE NETWORK

The report summarizes the characteristics of the U.S. public switched network and the maritime radio service, which impact the development of an Automated Maritime Mobile Telephone System (AMMTS). Features and performance parameters which appear desirable to an AMMTS user are reviewed, and some basic system concepts capable of satisfying these user's needs are presented. The interface between the public switched network and coast stations serving the maritime community is discussed in detail. Techniques for automatically placing a call to ships whose location is unknown are described. The development of an AMMTS involves a number of issues which may be different in the U.S. than in other countries of the world. The final section of the report defines some issues requiring further study.
