We’re looking for a decent Broadcom-based modem with 35b supervectoring support to bridge to an existing small business network. Nowadays they all seem to offer routing and wireless both of which we don’t need.

An affordable 17a modem would suit our needs for now, but it will need 35b support once our cabinet gets upgraded.

Any suggestions are much appreciated.

VMG3927-B50A or  XMG3927-B50A

But both offer routing/wireless...

Welcome to the kitz forum. 

Profile 35b is not used in the UK, so there may not be that many suggestions as to hardware which provide such support.

Thanks very much. We can get the XMG3927-B50A for €110/£99 ex VAT here. It is a shame we would just be using it in bridge mode though. Looks like there aren’t many if any modern Broadcom-based DSL modems that act as a gateway and nothing else. We may just give it a go. Cheers!

Cheers! Stumbled on Kitz whilst researching DSL. Very informative site. Got plenty of info which I couldn’t find anywhere else.

Out of curiosity, what is the max DSL downstream like in the UK? Is it 200Mbps bonded?

Yes except the Vigor 165 which is modern and 35b capable but uses Lantiq chipset not Broadcom but I just found this while typing,, it is a Zyxel 17a bonding and single 35b VDSL2 Modem Only so if you can find this product you will get what you actually need or you have to go with a modem/router Zyxel and use it just as a modem.

Thanks so much for sharing that cute little Zyxel! That one just may be it. Waiting for our supplier to get back to us.

I’m aware of the Vigor 165, but it’s Lantiq-based as you said and people’s experiences with it are very much divided from what I’ve seen. They’re also rather pricey here.

As for UK 200Mbps bonded,, I did never hear about that in the forum but the maximum single VDSL2 plan is 80/20 Mbps yet for sure people who have more than one line can bond connections from their end using load balance capable modem/routers line Draytek 2862/2865 or Tp-link load balance only routers (for ex.) to aggregate the speeds into one pipe.

Wow, that doesn’t sound too great. I hope there are at least alternatives such as cable or maybe even FTTP?

Sorry I had to delete my answer to your UK broadband speed question, since I am not from UK and probably will not have all the information about the broadband speeds there... it was partial information I knew from the forum.

No worries

There are.  Cable is available up to 1gbps in some areas from Virgin Media, and is expanding all the while.
Gigabit FTTP is available from various ISPs and CPs, through the incumbent Openreach network (network equipment dependent) and through various alt-nets such as CityFibre who are partnerning with VodaFone for consumer connections.

VDSL2 profile 17a is 80/20 maximum.

There is no VDSL2 profile 30a or 35b in the UK.

G.Fast is available at 330/50 maximum, but with limited coverage.

Cable is available to around half of the UK via DOCSIS 3.0 at over 500Mb but is being upgraded to DOCSIS 3.1 making over 1000Mb available.

FTTP (GPON) is available to around 3 million homes with 1000/115 being the highest common residential package.
Some ISP's are also selling 1000/220.

The UK also has quite a few smaller networks that provide FTTP.
Most of these also use GPON but some are point-to-point.

Thanks so much for the insight. Exactly what I was curious about!

Our supplier got back to us this morning. The Zyxel VMG4005-B Series is available for about £70. It sounds ideal for our needs, but I’ve been unable to confirm whether it’s actually Broadcom-based; are all Zyxel products? I might ring them later. Many thanks!

Are you able to share the contact details of your reseller?

The VMG4005-B is Broadcom and they also have a few MediaTek devices, i.e.VMG8623-T50A or VMG3927-T50K

. . . I’ve been unable to confirm whether it’s actually Broadcom-based; are all Zyxel products?

I downloaded the firmware images for both the VMG4005-B50A and the VMG4005-B60A. A comparison of the two binary files showed them to be identical.

A quick look at the contents of the binary file showed strong evidence of Broadcom --

I’d love to but it’s a local supplier. You would need a CRN, VAT number and address here.

I figured the B was for bonding Thanks!
