ADSL router line sync issue

[James Simpson]

Hi all

I have an issue with a 1921 adsl router I was running IOS 15.0(m5). I have upgraded to 15.1.4(m)

the problem is the ADSL wont sync with a BT line

The Firmware I have used is 4.0.15  and I upgraded the firmware to 4.0.17 and the line will still not sync.

I believe I need adsl2+ annex A or annex m. The fix that is needed is 4.0.195. This cannot be found on the cisco download section

can anyone help

Thanks in advance

If your circuit is Annex M, you need a specific router or interface card supporting Annex M. No software update alone will work.

And, to obtain firmware that you know it exists, but is unpublished, contact the TAC.

Next time for this kind of issues please post in WAN forum, not LAN.
