What Is SoGEA? Single-Line Broadband Without the Phone Line

Quick answer

SoGEA (Single Order Generic Ethernet Access) is broadband delivered over your existing line without an analogue phone line attached. It is the same FTTC-style connection many businesses already have - fibre to a street cabinet, copper for the last stretch - just sold on its own, so you stop paying line rental for a phone service that is being switched off. Calls move onto the internet instead. Expect download speeds up to around 80 Mbps depending on your distance from the cabinet, and installs measured in days rather than weeks.

As the phone network changes, you will hear this acronym from providers constantly. It sounds technical, but the idea is refreshingly simple: broadband without a phone line attached. Here is what SoGEA is, how it differs from what you have now, what to expect from it, and when it is the right replacement.

What SoGEA actually means

SoGEA stands for Single Order Generic Ethernet Access. The jargon hides a simple change: traditionally, business broadband came on top of a phone line, so you paid line rental even if you only wanted internet. SoGEA delivers the broadband on its own, with no analogue phone service attached.

In other words, it is the same kind of connection you may already have - FTTC-style broadband over the copper into your building - just sold without the redundant phone line. "Single order" is the whole point: one product, one order, one charge, instead of a broadband service bolted onto a voice service.

SoGEA vs FTTC: what is the difference?

This trips people up, so to be clear:

• FTTC (Fibre to the Cabinet) is the technology - fibre to the street cabinet, copper for the last stretch to you.
• SoGEA is the way it is ordered - that same broadband, but as a single product without a phone line.

So SoGEA typically runs over FTTC-style infrastructure. It is not slower or faster than the FTTC you may already have; it is simply unbundled from the phone line. If you are currently on FTTC with a phone line, moving to SoGEA is a billing and product change rather than a change in the connection itself, and in many cases it needs no engineer visit at all.

You may also see SoGfast, which is the same single-order idea over G.fast infrastructure where that is available, offering higher speeds than standard FTTC over short copper runs. It is worth asking about but not widely relevant.

What speeds to expect

The figure that matters most for a business moving its phones onto this connection is upload, not download. Every concurrent call, every video meeting, every cloud backup and every file you send competes for that upload capacity. A voice call itself is small - roughly 100 kbps in each direction as a rule of thumb - so ten simultaneous calls is around 1 Mbps, which sounds trivial.

The problem is contention rather than capacity. On a connection with 15-20 Mbps of upload, one large file upload or a backup starting mid-afternoon can crowd out voice traffic, and calls are what break up first. This is the single most common cause of "our VoIP is unreliable", and it is a connection issue rather than a phone issue. On SoGEA, configuring your router to prioritise voice traffic is not optional - see internet speed for VoIP.

Why SoGEA exists

SoGEA is a direct response to the PSTN switch-off. With the analogue phone network retiring on 31 January 2027, it makes no sense to keep selling broadband bundled with a phone line that is being switched off. SoGEA lets businesses keep their broadband working smoothly while the phone side moves to the internet.

It also solves a practical problem created by Openreach's stop-sell. Since September 2023 you cannot order new analogue lines, and most changes to existing ones are blocked - including broadband regrades on a line that also carries voice. SoGEA is the product that unsticks that, which is why providers reach for it. See our Openreach stop-sell guide.

What it means for your phone calls

Because SoGEA has no phone line, your voice service becomes a separate purchase:

• A simple Digital Voice line for a basic setup, or
• A full hosted telephony system for a team, or
• SIP trunks if you are keeping an existing phone system.

Business landline alternatives compares all of these properly. Either way you keep your existing number - it ports across unchanged.

Two things to plan while you are at it. Power: SoGEA and your router need mains power, so a phone on this connection will not work in an outage unless you fit battery backup and set up call diversion - see landline resilience and failover. And other devices: alarms, lifts and card terminals that used the old line each need their own plan, and an adapter on a SoGEA connection is not a safe answer for anything safety-critical. Start with devices that rely on phone lines.

The cost angle

The main saving is obvious: no separate line rental. Instead of paying for broadband plus a phone line, you pay for one connection.

That saving got considerably larger during 2026. Legacy wholesale line rental rose in three stages across the year, roughly doubling - see the WLR price rises - so dropping a redundant phone line is worth more now than it was in January. Set against that, you are adding the cost of a voice service, which for most businesses still nets out favourably because calls are typically inclusive rather than per-minute. Our business phone line cost guide has the full picture.

Ordering and installing SoGEA

Usually one of the easier things in the whole migration:

1. Availability check at your address, which your provider runs in seconds.
2. Order placed, with a target activation date.
3. In many cases no engineer visit is needed, because the line into your building already exists and the change happens at the exchange and cabinet.
4. Router configured - and this is the step worth attention, because voice prioritisation is set here.
5. Voice service ported and tested, then the old line ceased.

Typical lead times are days to a couple of weeks as a guide, which is much shorter than a full fibre install. That makes SoGEA useful when you are up against a deadline - but do not let speed of install push you onto it when full fibre is available.

Is SoGEA right for you?

SoGEA is a strong fit if:

• Full fibre is not available at your address yet. This is the main reason to choose it.
• You want broadband but do not need a traditional phone line.
• You are moving voice to a digital or hosted service anyway.
• You need something in place quickly.
• Your upload requirements are modest and you can prioritise voice properly.

It is the wrong choice if FTTP is available, and this is worth being blunt about. SoGEA still depends on copper between the cabinet and your building, and Openreach is retiring the copper network - the same exchange-level programme that stopped copper sales as full fibre coverage passed around 75% applies to SoGEA too. Installing SoGEA where full fibre already exists means slower upload now and another migration later. Our SoGEA vs FTTP comparison covers that decision in full, and the one question to ask your provider is simply: is FTTP available here?

The bottom line

SoGEA is broadband without the old phone line attached - a sensible, lower-cost connection for businesses moving off copper, especially where full fibre has not arrived yet. Pair it with a digital or hosted voice service, prioritise voice traffic on the router, plan for power, and you have replaced your analogue line cleanly. Just check whether full fibre is available first, because if it is, that is the better home for your phones.
