[comp.dcom.telecom] Aquatic Area Codes

GORDON MEYER <72307.1502@compuserve.com> (02/10/90)

A phreaker phriend of mine recently told me about the following area codes:

   871 - Atlantic, Caribbean, and Mediter. Sea.
   872 - Pacific Ocean
   873 - Indian Ocean

Has anyone heard of these before or was he pulling my leg?  He said
they were used, for example, to reach oil rigs and so on.

seas. They are linked into radio circuits, and used to reach ships in
transit from one place to another.   PT]

	These are the INMARSAT "Area Codes" for international high seas
	satellite mediated telephony [radio in a way].  

	Each ocean basin has specific INMARSAT satellites assigned to it
	so that when you prefix your call with that oceans' prefix, the 
	system looks for response in that basin.  

	As a side note there are several sites in Antarctica with INMARSAT
	ground stations and you have to know which satellite the site is
	using to call them.
