General Telephones

Push button and modern telephonesWith a growing number of telephone subscribers to cater for and improvements in technology so too the telephone began to become more advanced.  The rotary dial was replaced by push buttons but these early systems still used the same technology behind the dial – so called pulse dialling.  However, with the introduction of digital technology within the telephone network and the availability of solid-state integrated circuits, telephones became far more advanced machines.  Today’s  push button telephones use a system called Dual-Tone Multi-Frequency (DTMF) for dialling a number.  Here each pressing a key generates a unique combination of two frequencies and can be heard as an audible tone.   With this system it is not only much quicker to dial a number but also it allowed for additional keys such as the * and # to be introduced.  Electronics within the telephone provides for last number re-dial and the storage of commonly called numbers.   Advances in the network mean that ‘caller line identification’ allows for the number of the person calling you to be displayed on the telephone handset.  Today the telephone network doesn’t just provide the means by which you make telephone calls; it is your connection point to a whole digital world
