857 Int. Service Router - Annex-M

[Gary Turner]

Hi

I'm trying to establish if the Cisco 857 can support annex-m to improve upstream speeds, I'm aware I may need to change the ADSL firmware to do this but I cannot find any information if the router suports Annex-M.

Does anyone have any experience of the 857 on annex-M?

Thanks

Gary

Only 871-M routers (note -M in the part name) can support Annex M.

All other, do not support Annex M., and can not be upgraded to do so.
