It turns out that the BT Business Hub 3.0 is identical, in terms of hardware, to the BT Home Hub 3.0a.
See Burakkucat's thread for discussion on the Home Hub 3.0a and 3.0b [1]
Below are some snaps of the BT Business Hub 3.0..

The main components on the PCB of the BT Business Hub 3.0 are :
- Lantiq XWAY ARX168 dual core CPU in an LFBGA304 package [2]
- Hynix H5DU5162EFR 512Mbit (64MByte) DDR400 SDRAM in a FBGA60 [3]
- STMicro NAND256W3A 256Mbit (32MByte) 8x NAND flash in a VFBGA55 [4]
- Lantiq XWAY TANTOS PSB6972 seven-port 100Mbps ethernet switch controller in an LQFP100 [5]
- Two Lantiq XWAY PEF7071 gigabit ethernet PHYceivers in VQFN48 [6]

Hi guys,
@burakkucat
The results surprised me, too in several ways. Caveat though: the results could be wrong!
Neither the BT BH3.0 nor the HH3.0a or HH3.0b explicitly state whether the data rates reported in the GUIs are maximum attainable or real rates (minus overheads). But then if they are just 'real' data rates that would mean that the max. attain. rates must be higher. In which case the BH3.0 and the HH3.0a would rise the ranks to become the very best of the bunch!
I studied the boards of the BH3.0 and the HH3.0a closely and couldn't spot any difference. The DSP engine is integrated into the Lantiq ARX168 CPU. And the version number (1.2) of the CPU is the same in both the BH3.0 and the HH3.0a. So the marginally better performance of the BH3.0 compared to the HH3.0a could either be due to differences from manufacturing tolerances, or else the BH3.0 has an improved DSP driver in its firmware.
The firmware of the HH3.0a is reported as 4.7.5.1.83.8.57.1.3 (Type A)
The firmware of the BH 3.0 is reported as 4.7.5.1.83.8.77 (Type A)
As you have pointed out, the MAC addresses of the BH3.0 and the HH3.0a are both registered to Sagemcom, who apparently were once part of SAGEM (Société d'Applications Générales de l'Électricité et de la Mécanique), the French defence electronics giant. However, in 2008, SAGEM's communications arm was spun off into the hands of the private equity firm, the Carlyle Group, and it trades today as Sagemcom.
From http://www.sagemcom.com/UK/about-sagemcom.html :
Sagemcom is a French high technology group, active globally . Thanks to its proven capacity for innovation, the group is in a leadership position in many markets. Sagemcom aims to become a world leader in broadband terminals, convergence and energy solutions. Formerly the Communications Branch of SAGEM, Sagemcom is now a private independent group held by the Carlyle Group, as well as employees.

Yes, the Huawei (but probably not the ECI*) supports VDSL2, ADSL2+, ADSL2, as well as ADSL1 (G.Dmt) and its N.American equivalent T1.1413.

Of course, it's possible that the reported line statistics are false in any or all of the GUIs.
Lies, Damn Lies and xDSL Statistics, as someone once said!

* EDIT: it seems that the VRX268/VRX208 chipset in the ECI is multi-mode VDSL2/ADSL capable. Hopefully those capabilities are supported in the Openreach firmware [1]
