Thomson/SpeedTouch and Annex M

[J. J. Farrell]

I noticed that the LLU hardware tests page (http://adsl24.co.uk/support/llu/) shows that the Broadcom-based Thomson routers don't support Annex M. I beg to differ as evidenced below :)

Uptime: 32 days, 17:26:39
DSL Type: G.992.5 Annex M US 56
Bandwidth (Up/Down) [kbps/kbps]: 2,277 / 22,099
Data Transferred (Sent/Received) [GB/GB]: 1.49 / 11.06
Output Power (Up/Down) [dBm]: 13.0 / 18.0
Line Attenuation (Up/Down) [dB]: 11.0 / 21.0
SN Margin (Up/Down) [dB]: 3.0 / 3.5
Vendor ID (Local/Remote): TMMB / BDCM
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 0 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 28 / 0
FEC Errors (Up/Down): 125,134 / 0
CRC Errors (Up/Down): 125,134 / 24,090
HEC Errors (Up/Down): 38,276 / 13,600

Most (all?) versions of Be's BeBox are rebranded versions of these routers, and they certainly support Annex M since it's one of Be's features. The graphs from the BeBox/SpeedTouch stats analysis site at http://be.nfshost.com/ show lots of Annex M data points.

Hi

It's because not all of them do. Only the 585v7 and 780WL (i think) support Annex M

It might be an idea to list the Thomson routers that support Annex M separately from those that don't.

The stats above are from a 585v6, and I think it works on the rest of the family - someone was using Annex M on a 536v6 a couple of years ago.

From firmware 6.2.G onwards (aka 6.2.15, released about 4 years ago) it can be configured in the CLI; in earlier firmware versions it can be enabled by twiddling the modem options. I'm using firmware 7.4.3.2 on the 585v6, and it's rock-solid with low SNR margin, as shown above.

Currently two pages conflict.

This page says the 585 can't handle Annex M:

But this page says it can:
