I'm trying to set-up a C1760 voice gateway with a VWIC-1MFT-E1 connecting to an ISDN30 PRI (E1)pri-group timeslots 1-8,16 on the controller E1 I get the following message:
%Controller tdm clock does not have data capability
Any idea's why I can't do this???
Thanks,
Chris

This behavior is only seen when the c1751 or c1760 voice gateway has a T1/E1 VWIC installed and the T1/E1 controller is in a DOWN state, either due to an actual outage or even due to administrative shutdown. The T1/E1 controller can be set up for a voice pri-group, voice ds0-group, data channel-group, or even nothing at all -- the key is that the controller is DOWN. Once the T1/E1 controller is brought back up the OUT STATus for all POTS dial-peer will return to an UP state and calls may terminate again on those POTS dial-peers.
Workaround:
===========
Configure the command

Do you have any DSPs in the router?
If memory serves the PVDMs should be listed on a show version. show voice dsp will give you more detail.
You need at least 8 DSP channels.
Please rate helpful posts.

The issues was resolved by placing the VWIC-1MFT in slot 0 of the 1760 (rather than a voice slot).
The router did have DSP's, but would only allow data configurations in the E1 when install in a voice VWIC slot.

Actually, all 1760's four slots are voice slots.
But, only slot 0 and 1 are also supporting data.
So, a VWIC that is to be used for data, must be placed in these, as you have found yourself.
