I’ve not seen it, but if you are driving 4 PRIs you will definitely have to do it. The DSPs are the same type just different capacities, but the DSPs used for TDM to IP conversion that a PRI needs must be on the PRI NIM in an ISR4XXX. You can still use the extra capacity for transcoding etc.

[EXTERNAL] Has anyone dealt with the PVDM's being put on the Motherboard and it's supposed to be on the card? I got a new 4431 and the 256 was put on the motherboard and the 32 was put on the 4 PRI port card. TAC is advising to switch the location of the two PVDM cards. Does this sound correct? TIA Scott
