So my previous email was not very clear. Of course an analog port will require DSPs to convert the analog signal to digital. However I was thinking of the old days where an analog port required an NM-2V which had the DSPs to be used for the analog ports. In this case the PVDM DSPs went into the NM-HDV module and were thus used with the E1/T1 ports or for dspfarm resources.<div><br class="webkit-block-placeholder"></div><div>The DSP Calculator Wes linked shows that for a 2811 with (2) VIC2-FXO modules in slot 0 and slot 1 doing 4 g.711 calls it requires 1 PVDM2-8. Since this is probably the smallest PVDM we have I can't say how many of them will actually be used. or how it allocates them when you have more than one PVDM present.</div><div><br class="webkit-block-placeholder"></div><div>Either way you'll have plenty of extra DSPs on that box.</div><div><br><div><div> <p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="3" style="font: 12.0px Helvetica">-Ryan</font></p> </div><br><div><div>On Feb 21, 2008, at 10:12 AM, Ryan Ratliff wrote:</div><br class="Apple-interchange-newline"> AFAIK your router will not use any DSPs for analog ports.
