Howstuffworks.com Not only is a telephone a simple device, but the connection between you and the phone company is even simpler. In fact, you can easily create your A telephone network is a telecommunications network used for telephone calls between two or more parties. There are a number of different types of telephone network: A landline network where the telephones must be directly wired into a single telephone exchange. This is known as the public switched telephone network or PSTN.

Examples of signaling between a telephone user and the telephone network include: dialing digits, providing dial tone, accessing a voice mailbox, sending a call-waiting tone, dialing *66 (to retry a busy number), etc. SS7 is a means by which elements of the telephone network exchange information. Information is conveyed in the form of messages. The local loop, which connects a telephone to a local exchange is a two-wire (2W) circuit that carries the signals in both transmission directions. Even asymmetrical digital subscriber lines (ADSLs) use this same 2W local To connect a 2W local loop to a 4W network a circuit called a 2W/ 4W hybrid is needed.
