Hardware transcoding and DSP resource

We have 3845 router and NM-HDV2 module. If i am configuring E1 link, Will it be enough 32-PVDM2 for normal PSTN call for full utilization of E1 channels ?

Will i be able to configure hardware transcoding with this PVDMs or Do need more PVDM2 cards ?

Re: Hardware transcoding and DSP resource

Hi, the number of calls depends on the codec used, you can see the PVDM requeriments at the link (Table 2):

For hardware transcoding you need more PVDMs.
