A. No. You cannot install PVDM3 modules directly on the PVDM slots of an NM-HDV2, only the PVDM2s are supported by the NM-HDV2. However, an NM-HDV2 that has no PVDMs installed at all can share PVDM3 DSP resources from the router motherboard PVDM slots across the chassis backplane.
But you have to enable the pooling of PVDMs in some way. Take a look at this thread and rate if useful:
Finally, bear in mind that you have a PVDM3-32. Your 4-port FXS card will be assigned 4 channels permanently at router startup, leaving 28 channels. So you still won't have enough to run all 30 channels of your E1 card.
You have a single PVDM3-32 in your router, and a 2921 has 3 PVDM slots. So you can just add further PVDM3 modules...
The '32' in the name is the number of supported channels. So for a 30-channel E1 you need 30 out of your 32 channels. Be aware that if you are using more complex codecs or want to do hardware conferencing or transcoding on this router, that will also use up channels.

If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
