cris_jimenez · ‎11-20-2009

Hello,

I want to connect 2 PRIs to a 2811, I'm using the DSP calculator and it says that for 48 calls all g711 u law I need

2 DSP(s).
one PVDM2-32

or

two PVDM2-16

I have a spare PVDM2-64

that should be enough, right?

or do i need 2 PVDM2-64

thanks

also do you have a document that will explain the pvdm types like 2-32, 2-16, 2-64 and so forth

thank you

Yes, a PDVM2-64 will be enough and you'll also have some channels left.

Each DS0 from the PRI that carries voice uses 1 channel, and you have 64 on that DSP.
