33.6 K Analog modem to a 56K AM module

[utawakevou]

I have a 3661 router with a 16 port Analog Modem(33.6K speed) module . I want to replace the 33.6K speed with a 16 port analog modem(56K speed) module.

Is that possible ? Will I need to change any config or settings ?

If you're talking about the NM-16AM, the link below says it's not possible:

Thank you. I did have a look at that link. Does this mean that there is no analog modem module for 3661 router that can support up to 56K ?

There's the wic-1AM and wic-2AM that support V.90 client mode (i.e. 56k when dialing to a V.90 server modem) so they are still limited to 33.6 for dial-in use. And obviously they provide a much lower port density and require a network module that supports wic's.
