Cisco 857 - Annex A to Annex B

[Emilijano651]

Boys and girls,

I need a bit of help here. Is there any way I can make the cisco 857 router work on ADSL over ISDN? Any idea, no matter how crazy, is welcomed.

Thanks in advance,

Emil

Hi Emil,

More likely you will not be able to use ADSL over ISDN, there is no ISDN support on 857. It is possible if you use cisco 876 or 836.

If you want crazy idea here is one you have to use TA on router side. Then you have to terminate the ISDN line on the other end convert it to POTS  and then connect it to MDF....HDF, DSLAM which is connected to the provider's network.

Regards,

Alex
