Unbreakable in bridge mode???

scottydj2 — Tue, 06 Feb 2024 13:54:50 GMT

Hi,

Can anyone give a definitive answer on whether the unbreakable (EE dial-up) mode will work when the smart hub is in bridge mode (business version)?

Tech support seems to think it should. Practice with ethernet cable between the two says it doesn't.

From a technical standpoint, it shouldn't matter about the mode. If the ADSL/Fiber goes down, switch to 4G.

Thanks,

Scott

Welcome to this user forum for BT Retail phone and broadband customers.

I assume you are a BT Business customer?

It would be best to ask on the BT Business Forum, as a residential user would be using the BT Smart Hub 2.

I have no definitive answer but bridge mode would imply routing is disabled. I'd expect that to include comms with the 4G device, so I'd expect it not to work.

Thanks Keith.

I may be about to become a business customer, depending on the answer.

Wasn't aware of the business forum. I'll ask there.

Thanks.

Scott

The BT Business backup is totally different and uses the USB port on the Business Hub.

@Keith_Beddoe

That's interesting. I see from the doc it's dated 2019.

Has the hybrid-connect product with EE superseded this ?

I think I should have used the term 'Hybrid-Connect' rather than 'un-breakable' above.

Thanks @Anonymous

Agreed, but it's at the physical link level this should be working is it not?

ADSL/Fiber link goes down, switch to 4G. Routing is the layer above.

I am not aware that BT Business has changed anything on their backup method, but I do not follow closely the developments on the business side, it more of a passing interest, as I used to maintain those services before I retired 14 years ago, and then its was ISDN or ADSL backup.

I am sure if you look at the BT Business Sales page, it will tell you whether 4G Assure is current.

I think this is the answer you may be looking for https://business.forums.bt.com/t5/Broadband/4G-assure-and-Bridge-Mode/m-p/85119

I'm thinking that because the "path" to the 4G device is over ethernet, that can't exist without routing enabled.

Also in bridge mode you're going to be handing off account credentials to another device, so probably no way for the SH2 to then validate that you subscribe to the service.

All pure speculation though...
