2811

Unanswered Question
Aug 27th, 2007

Hi

i have 2811 with PVDM2-16 and 4 ports FXO, so each port will take a channel from PVDM2-16, the remaining is PVDM2-12, I want to do HW conference resource using these PVDM2-12, is it possible to do this, since I get that not enough DSP resources when trying to create conf profile?

is it a limitation so that i can not share between termination for fxo ports and conf resource in the same PVDM2-xx module? or something else?

appreciate kind helps?

thanks

thanks Dragi for ur response

so i will have PVDM2-12 channels not used !

then if i have 2 PVDM2-8 modules, and I want fxo 4 ports to consume PVDM2-4 from module 1, then i thnk i can make conf resource from the second PVDM2-8 module? right?

Hi,

PVDMs have different DSP counts. PVDM2-16 has one DSP, PVDM2-32 has 2 DSPs and so on. If you wan to do hardware conferencing with DSPs you must dedicate at least one DSP for that (note the difference between a DSP and a PVDM!) or more depending the number of conferences you need to support.

In your case you should put the PVDM2-8 on PVDM slot 0 so it will be used by the FXO ports and the PVDM2-16 on slot 1 (these slots are on the PCB of the router).

The lowest PVDM I recommend you to use for conferencing is PVDM2-16 since PVDM2-8 is a low cost one DSP module and is not fully functional as the PVDM2-16.

BR,

Stoyan

thanks Stoyan for ur really helpful answer,

but note that i have just only pvdm2-16 card being put in slot0, then i got from ur answer it is not possible to do conf using hw resource (conf profile) with this same pvdm2-16 card keeping in mind that fxo will use 4 channels?

thanks sstoitsev

is this same case valid for HW conference resource for MoH or not?

i mean i want to utilize the existing pvdm2-16 as HW dsp resource fro MoH can i accomplish this? how?

or is it needed to have a seperate PVDM2-xx also?

thanks again

appreciate ur help

MoH needs either HW resources or SW resources, what i meant is that i have 2811 with pvdm2-16 and 4 ports fxo, can i utilize this pvdm2-16 module for both fxo termination and as HW resource for MoH?
