How traditional telephony works
Traditional telephony utilises copper pairs to route the call through a series of public exchanges (PSTN), and then on to the endpoint receiver by using analogue signalling.
Why Openreach are withdrawing the network
This network has been used in the UK for well over 100 years, with little change to the infrastructure. As such, the underlying hardware is degrading and maintenance is costly. Use of the PSTN has also been declining as mobile has become more popular, meaning the costs of the upkeep were no longer justified.
Furthermore, the increasing availability of broadband, which is supported on this network, has meant that the PSTN has evolved into an almost completely digital network. This means there is no longer a requirement for traditional fixed line telephony.
What is the future of telephony?
Openreach are now moving forward with a fibre-first philosophy, bringing superfast connectivity to more locations throughout the UK. These more reliable and robust networks will enable users to access broadband that is capable of supporting IP communications. VoIP will become the replacement solution for traditional telephony, particularly in businesses, however, this technology will not be provided by Openreach. Communications Providers will have to administer and maintain the over the top voice service themselves, giving them the opportunity to bundle connectivity and voice services together and capitalise on convergence.
