Link, data link

I would like to ask if these two definitions of link are the same and if they both mean "data link" .

Link: Part of a communication or transport system. "The company has telephone links to its branch offices." ->Newbury House.

Link:An interconnecting circuit between two or more locations for the purpose of transmitting and receiving data [data link as synonym]->WordWeb.


Thank you.

The first definition is broader. It includes transport systems, which are not "data links", and telephone links which, when used for voice communication, would traditionally not be "data links", though nowadays the boundaries are more blurred since voice traffic may be carried as "data".

Maybe something like "We get our Internet access over a satellite link".

hhttLink: Part of a communication or transport system.

Examples:

 Sanford airport in Florida has no public bus link to Orlando, the city it serves. 
Express bus services link the main towns with Glasgow, Ayr, Edinburgh and Carlisle.
 Many large cities with intracity rail link the rail network

Or physical link.

'data link' I suppose captures an abstract idea. In communication, there must always be a link through which data is transmitted, and data may be in any form--digital or analogue. I think of 'data link' as the exact part of the link (or the whole protocol) which handles necessarily data.
