SOGEA Spelt Out [Guide]


The latest in a long line of telecoms-based acronyms? Yes. But do you need to get to grips with it and understand what it means? Also yes.

SOGEA stands for Single Order Generic Ethernet Access and is the newest product from Openreach which enables you to order Fibre to the Cabinet (FTTC) without a phone line – meaning you’ve quite literally got everything you need within a single order. SOGEA will bring yet another big shakeup to telecoms in the UK and it is one that we cannot afford to ignore.


At the moment, most businesses connect to the telecoms infrastructure using Wholesale Line Rental (WLR) with broadband then added on top. As a result, Internet service providers (ISPs) then bundle these together as packages by default.

However, in today’s technology-driven world, most organisations only have this fixed line because it is necessary for their broadband to work. With the advancement and cost-effectiveness of mobile handsets and VoIP and the nationwide roll-out of full-fibre networks, there is less and less requirement for old phone services.

End of the line for PSTN and ISDN

Speaking of old phone services, in the biggest change to telecommunications in 30 years, the PSTN and ISDN will be switched off by December 2025, and a Stop Sell of these services is scheduled for 2023. This means connectivity will no longer be supported by traditional telephone lines and businesses will need to switch to a new, single order broadband product.

SOGEA was created in response to this shift in usage so that both consumers and businesses alike can buy a broadband connection without the need for a phone line.

Finding your voice

The drawback to this service is that SOGEA users will no longer have access to a phone number, as it does not allow users to connect a traditional phone line. However, the good news is that Daisy can overlay OnlineUC Phoneline+, a single user voice service that resides in the cloud if needed. If you have an existing ADSL service with an analogue line and want to migrate to SOGEA, we can port and deliver the Calling Line Identity (CLI) of the analogue line via our OnlineUC Phoneline+ voice overlay service. This allows you to make voice calls and supports analogue data services like a fax machine.

How SOGEA works

Based on the current Fibre to the Cabinet (FTTC) technology, SOGEA uses a combination of copper and fibre technology, without requiring a traditional telephony connection. Fibre technology is used from the local exchange to the PCP (green street cabinet) and then copper from the PCP to the premises.


The big 2025 switch-off timeline

The Public Switched Telephone Network (PSTN) will reach the end of its life in December 2025. After this date, any services supported on Wholesale Line Rental (WLR), including Single Analogue Lines, Multi-Lines, ISDN2 and ISDN30, will need to move to alternatives.

The big switch-off will also impact LLU SMPF, SLU MPF, Narrowband Line Share and Classic Products. The switch-off will impact broadband customers as well. Most broadband ADSL and FTTC services are supported by Single Analogue Lines. When this service is switched off, the broadband product will need to move to a Single Order variant.
