Likely you don't have enough dsp for bot E1 and 4 fxs, that requires 34 channels and you might have a pvdm2-32 only.

As a temporary workaround you can reduce the number of timeslots in pri-group.

Hope this helps, please rate post if it does!

The E1 use 30 or 32 channels?

In case are 30 if I use VIC2-2FXS would be accepted?

30 channels, but you can reduce this number to 28 with pri-group command under controller E1, and nothing bad will happen.
