I just tried to validate a config for a 2801 that will have three T1s bonded together and had used the VWIC2-2MFT-T1/E1 card to get a decent port density. The config was rejected because I did not have any DSPs in the router. Is this really a problem? If the MFT cards will only be used for data and not voice will it work without them?
I have this problem too.
