I am looking at the 2900 series G2 routers to supply 6, 10 and 12 PRIs in one device. It looks to me that the 2901 can support up to 8 PRIs using (2) 256 PVDM3s and (4) vwic2-mft-2t1/e1. Will that work?
With that said the next step up would be the 2911 and it supports one one NM. Can I get the 12 PRIs if I use a NM-HD-2T1, an additional vwic2-mft-2t1/e1 and 4 PVDM2 modules? I was not sure about the mixing of the PVDMs when using the NMs.
