Joining EE - Is it possible to run two networks into one Full Fibre Connection?

Tilly38 — Thu, 21 Aug 2025 12:18:26 GMT

My sister is disabled and lives in a supported living environment. She is due to switch from Plusnet to EE full fibre internet in about a month. At the same time the phone line will switch from Plusnet (copper line) to EE digital. However the carers are already using the full fibre connection for their (separate) internet network with a different internet provider, and their router is plugged into the full fibre terminal. My question is - is it possible to have two separate internet networks on the same full fibre connection, and if so - how would it work? Is it possible to plug more than one router into the full fibre terminal? I rang EE they said to just plug the new EE router into the ADSL line (the Plusnet router is currently plugged into the ADSL line) and to plug the phone into the router. But I’m not convinced this will actually work, if my sister is switching to full fibre internet and digital phone line?

Not on the same Full Fibre connection.

As it seems that she has already ordered from EE, they will lay on a separate Full Fibre connection for her leading to her room hopefully.

@Tilly38 Don't be following any of the EE advice just now as on a none active EE line that is not possible, especially if there is currently no DV circuit supplied, after EE take over yes, and please be aware that the landline phone on a DV circuit has to change from one supplier to the other, it may be out off operation for 24-48hrs during the change period. Outgoing and Incoming are two separate systems to the DV along with all the systems that have to connect through to the Landline operation!

Just leave the Talk Talk line until the switchover date!!!!

Although this is not easy, you need to get with your sister, get the vulnerable person status all sorted out with EE and that is NOT going to be easy or straight forward, look at ALL the battery backup system that NEED to be done for ALL the devices especially depending on the disability that has to be covered! Assisted living may not be as forceful as they should have separate and independent Alarm system for emergency purpose. No Fibre then NOTHING works!

If the carers and your sister occupy the same physical address, then you're going to struggle I think.

Openreach have toyed with the idea of 'multiport' ONTs (fibre terminals) in the past (example here) but I doubt you'll easily find a commercial ISP that is capable of accommodating it.

It wouldn't surprise me if there ends up being a request against the carer's existing fibre service to transfer it to EE (again, assuming the two dwelling units aren't defined as separate addresses).

Interesting Question ... Since I think over 100 FTTP connections (ONTs) are running on 2 fibres in my village 🙂 ... OPENREACH use fibre splitters( something like 1 to 32 ) in each pole/hole mounted CBT and then concentrate them in a AGG (regation) node .

I think splitters are prismatic , but combining and segregation of data must be dependent upon coding within packets.... really beyond me but not beyond the whit of man 😁

The easiest way to effectively achieve a totally separated network on a single connection is to have a separate VLAN with appropriate firewall rules, but this is not something for normal residential users.

True but not really relevant to the question here, which is exploring two fibre connections (with different ISPs) from the same ONT .

Fun (?) fact: All ~32 of those FTTP connection all 'see' each others traffic at the ONT layer, it's just the ONT selectively decrypts the bits that are meant for you.

I thought of suggesting this too but like you say, definitely not for the faint of heart! This solution would involve a single ISP connection and using a third-party router/other kit to configure two separate local networks (one for the carers and one for the sister). The bandwidth would be 'shared' but neither party would be able to 'see' each others network etc.

I was conjecturing if it would be possible(for OPENREACH) to disconnect the fibre from the ONT and put another splitter on the fibre and install a 2nd or 3rd ONT .... just thinking out loud 🤔
