Communication Networks

A telecommunications network is a collection of links, terminals and nodes which are configured to enable communications between users of the terminals. Each terminal in the network has a unique extension or address so messages or connections can be routed to the correct recipients.

The address space is the collection of all the addresses in the network. The links connect through a system of the telecommunications network using message switched, circuit switched or packet switched routing.

Examples of communications networks are:
• Computer Networks
• A Telephone PBX network
• The Internet

There are a number of different types of telephone networks:
• A fixed line network where the telephones must be directly wired into a single telephone exchange. This is known as the public switched telephone network or PSTN.
• A wireless network where the telephones are cellular or mobile and can move around anywhere within the wide coverage area.
• A private network is where a closed group of telephones are connected primarily to each other and use a gateway to reach the outside world. This is usually used inside business or company locations, call centers and operators and is called a private branch exchange or PBX.
