For businesses who use phone
lines to provide services
Digital Services Test Lab
Our Digital Services Test Lab provides an environment which emulates some of the conditions found when an analogue line migrates to a digital line.
This enables vendors of hardware used on the UK telephony network maintained by Openreach, to test their products in an environment which emulates some of the conditions found when an analogue line migrates to a Digital line as part of the All IP Programme.
The All IP Programme has been running since May 2018 and covers the switch off of the current WLR (Wholesale Line Rental) portfolio by the end of 2025. In readiness for this, Openreach has rolled out Fibre to the Cabinet (FTTC) to 95% of the UK and made Ultrafast Full Fibre (FTTP Fibre to the Premises) available to more than 5.6M premises so far.
The programme migration time scales will be in the hands of your Communications Provider who buy services from Openreach. There are more than 660 Communications Providers in the UK, including SKY, TalkTalk, Vodafone, BT and Zen. Openreach does not recommend any of these companies over another.
Product testing
Our Test Lab offers a variety of lines for testing including:
- WLR (Wholesale Line Rental - PSTN, ISDN2, ISDN30)
- FTTP (Fibre to the Premises)
- SOGEA (Single Order Generic Ethernet Access)
- SOGFAST (Single Order Gfast).
We also plan to install SOTAP (Single Order Transitional Access Product) lines at a future date.
