Hi Folks,
I have a 887G router with ADSL connectivity to my service provider. I can sync at;
DSL Mode: ITU G.992.1 (G.DMT) Annex A
The service provider offers higher speed connectivity vioa ADSL2+ but my router must support Annex M. As far as I'm aware from the Cisco docs it should support but it will not sync up. I think that I should see Annex M as an option uner the line config but I don't.
Router(config-if)#dsl operating-mode ?
adsl2 ITU G.992.3 Annex A and L
adsl2+ ITU G.992.5 Annex A
ansi-dmt ANSI T1.413
auto auto detect mode
itu-dmt ITU G.992.1 Annex A
<cr>
Router(config-if)#dsl operating-mode
It's also not an option as some documents describe as an extension to the command;
Router(config-if)#dsl operating-mode adsl2+ ?
<cr>
Router(config-if)#dsl operating-mode adsl2+
I think that my IOS may not support it, I am running version;
Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 15.1(3)T1, RELEASE SOFTWARE (fc2)
Does anyone know what IOS that I need to support Annex M?
Thanks in advance,
Shane.

As mentioned above:
Only specific 880 series models supports Annex M.
In the document you linked, look for these on Table 19.

Hi Shane--This Community Forum area is for Cisco Small Business Products. The Cisco 887G Router is not a
Cisco Small Business Router. You might want to post this at the Support Community that supports that type of router.
THANKS

It's not IOS matter, you need a specific -M model to use Annex M, that is CISCO887VA-M-K9
Try asking your ISP to downgrade you to non-M.
Next time you can ask in WAN Routing and switch as you have a true IOS, Enterprise product, not Small Business one.

Thanks for your reply - I was afraid that it might be a hardware issue, however according to the DSL specifications on the following page, the 887 is shown to support Annex M,
This is why I thought my problem was IOS related.
Thanks,
Shane.

Regarding the new 887-VA models with the Broadcom multimode chipsets, Annex M support will apparently be added to the Annex A models in a future IOS release. This is, of course, no help to the OP if he has an older ST Micro based model.

Q. Is Annex M supported on the Cisco 887VA Annex A platform?
A. At product FCS, Annex M is not supported on the Cisco 887VA Annex A platform. Annex M support will be enabled on the Cisco 887VA Annex A platform with a later Cisco IOS® Software release.
