DV Over non-Full Fibre

XRaySpeX — Fri, 18 Oct 2024 10:27:58 GMT

Is it possible to have DV over FTTC or even ADSL? The VoIP signals can still come over copper to the home & all it would need is simple modem router with an integrated DECT base station &/or a phone socket.

Hey there @XRaySpeX!

My understanding was that all new home phone connections taken will be via Digital Voice, and this will be supported on all broadband types

I've run a check of a family member's address where FTTC is the only service available, and this was the option that was offered.

I've had DV on FTTC for 5 years now @XRaySpeX .

@XRaySpeX Only thing i would look at carefully would be on a very slow ADSL line is the upload speed, that is where the strain would be for any kind of system, especially now moving the landline onto that type of connection and trying to use broadband at the same time.

Standard PCM channels used in the PSTN network are 64Kbps so carrying that even on slower ASDL is easily possible, the challenge come with prioritising voice traffic over anything else to give acceptable quality is the challenge.

BT/Openreach have already converted a number of lines around the country from the old PSTN to DV, must pay a visit to a mate who has it done to see the details.

@Mustrum Most people with older slow ADSL lines do know not to push the envelope to much regarding there internet, adding voip should not kill it, and as you say manage the expectations. If anything it may actually get better with everyone kind of moving to fibre will free up some of the bandwidth.

@JimM11 : Since when does living in an area with slow BB speeds imply a lack of technical knowledge?

@JimM11 the shocking thing is the lack of understanding, information and publicity available.

It is not rocket science, but it seems more people would do better on a rocket science test that a DV and how it impacts' me test!

I have just transitioned from BT (on FTTC with BT SmartHub2 & DECT on DV port working fine) to EE (FTTP installed yesterday), but the phone not working (error not dial tone). The EE callcentre Tech said my old hub wasn't compatible with EE, and will now send me a replacement EE hub (I have to return the old one). I am concerned ..
1. why H/W incompatibilities (not just firmware/config fix), given all the standards compliance?
2. EE router should have been provided early (like the red-end cable that I WAS sent before install)
3. I am temporarily without my landline
4. other posts here complain same number transitions may add delay
5. installer said circuit "may take 28 days to settle": surely such adjustments only needed for copper to recalibrate ?

@DickInKent The BT Smart Hub 2 has an ATA port to connect your landline phone, The transition from FTTC/FTTP is the one, and your Phone just may take 24-48hrs to swap over.... Lan port 4 is were that BT hub connects to your new ONT, and you do have to check that EE has not dropped your landline off with your Transfer to them.....

Were you using the Dect side off the BT Smart Hub 2 connected device wise? https://192.168.1.254 that will allow you to connect and look at your BT Hub. Do think carefully if you wish to keep the BT one or head down a rabbit hole EE Hub depending what they send to you.

BT Forum will be able to say what the current FW for your hub is at, think last update was around the December timescale.

From the BT Forum, that i could see one posted.....

As of April 2026, the current firmware version for the BT Smart Hub 2 (SH2) is v0.45.00.08028

My BT SmartHub2 has a DV port to my DECT hub. It all worked OK under BT ISP but EE ISP stopped as I noted. From the admin port (192.168.1.254 and admin login) the Home->Advanced settings->Technical log shows
Firmware version:v0.46.02.10311-BT

Firmware updated:Wed Dec 3 00:35:24 2025
Board version:R01
GUI version:2.0.1 30_06_2025

but my Q about standards (why need to change H/W?) stands

Re: DV Over non-Full Fibre

@DickInKent That's it you do not need to, the BT Smart Hub 2 will work as expected DV wise, EE app and not fully as a later version like the EE Smart hub 6/7 Plus or the 7 Pro for parental controls etc. See the link below to the current EE and BT Versions. The EE Smart Hub Version SH20A is the equivalent but NOT identical to your BT Version.

Different types of BT Hub | Broadband Help | BT | BT Help

You should see on that BT Hub your registered landline Phone number, and all the details about it first page front and centre.

EE told you a load of B S.

Edit:- Question who moved you over, did BT do it, did EE do it, or did you do it all yourself?

From WSH on the BT Forum so does look like you may be on the latest currently.

Yes, it is v0.46.02.10311-BT.

I've been running that since the 12th of December, (and I'm usually late to get it).

There was posts about a later build version, 0.46.02.42261, but it seems to have caused problems so I think they pulled it.

Time-wise, we must be about due for a v47.

@JimM11 Facts ..
1. the BT SmartHub2 with my DECT hub on DV port had worked happily for 24mo
2. the FTTP installation c/w ONT was done by Kelly Comms (contractor)
3. broadband (incl WiFi from my prev router) works fine (good speeds) but DECT fails
4. call to EE tech eval'ed [quickly as known prob] and EE sending new hub (model tbc)
5. [hopefully Mon 24/8] we will see if my DECT works with new EE hub
6. your statement that BT SH2 will work is b/s, and your rubbishing EE premature
7. my expectation [given intl stds] of H/W compat stands, so reason for fail (#3) unknown

I will report result (after #5) and what EE hub model actually supplied
- BTW I won't return BT SH2 unless/until new hub works for both BB and DV
