Analogue telephone lines can still be found in business premises and residential properties throughout the UK. The analogue network is known as the PSTN (Public Switched Telephone Network). It enables you to make calls through your local telephone exchange, via a network of copper wires, but you need a telephone that’s plugged into the wall.
Analogue telephone lines provide users with limited functionality. You can only have one telephone number per line (although you can have extensions, enabling you to have more than one handset), and you’ll only have access to basic call features.
Analogue telephone use is declining in the UK, due to the increasing popularity of mobile phones and internet based telephony systems. It’s likely to continue to fall as residential customers gain access to broadband services which don’t require them to have landline telephones, and those running businesses from home are able to modernise their telephone systems.
Digital Business Telephone Lines – All About ISDN
Digital telephone lines were first introduced in the late 1980s. They quickly became attractive options for businesses, as they provide far more functionality than analogue lines. Digital lines enable businesses to have multiple channels. They also allow companies to allocate Direct Dialling In (DDI) numbers to different departments and individual employees, so customers can get straight through to the person they need to speak to.
