DSPs / PVDM2s combination question

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:

7 DSP(s).

one PVDM2-48 + one PVDM2-64

or

one PVDM2-16 + one PVDM2-32 + one PVDM2-64

or

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.

Hi Mark,

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!

Re: DSPs / PVDM2s combination question

that's 6 DSPs, you're one DSP short with that PVDM2 you have on hand.

without knowing the exact requirements no one can answer if that's enough or not.

Re: DSPs / PVDM2s combination question

Well the location is getting upgraded from about 8 analog lines to a single PRI DID.

They will still have a couple fax devices and analog lines that are active as well as a little bit of conferencing capability.

All the existing analog lines and conferencing capabilities were already working fine with the 2 existing PVDM2-32s.

The router had the capacity for a lot more analog services than we were using...it was not maxed out or even close to being maxed out.

So I guess what I am trying to determine is if an additional PVDM2-32 will be enough additional resources for the PRI DID.

It would be great for convenience and cost savings but if it doesn't seem feasible I will purchase the recommended hardware.
