I used the DSP calculator and it recommended that I need a total of 7 DSPs for one of our routers.
The PVDM2 combinations in the output are:
one PVDM2-48 + one PVDM2-64
one PVDM2-16 + one PVDM2-32 + one PVDM2-64
one PVDM2-16 + two PVDM2-48
The router currently has 2 PVDM2-32s installed and I have another PVDM2-32 on hand.
I am wondering if I can just install this additional PVDM2-32 and be ok even though it is a bit less than what the DSP calculator recommended.
I would think you should be good to go here! The PRI should only require 23 DSP's (1 per B-Channel)and you are adding 32. I'm guessing that the DSP calculator may have been looking at a 2-port PRI Module instead of just the 1 PRI that you will be adding :)
Hope this helps!
