Telecommunications network
From Wikipedia, the free encyclopedia.

A telecommunications network is a network of telecommunications links arranged so that messages may be passed from one part of the network to another over multiple links.

Telecommunications network links may in turn be built out of hierarchical transmission systems.

Examples of telecommunications networks are:

• Computer networks
• the Internet
• the Public switched telephone network
• the global Telex network
