I have a 3845 router voice bundle with 2 x NM-HDV2-2T1/E1. The load on the lines is 50%; i.e. maximum 60 channels will be carrying calls simultaneously. However, the router does not allow me to enable all four E1 interfaces. Is there a way to operate the 4 E1 lines with the on-board PVDM2-64?
For analog circuits, you cannot 'share' DSPs. These are allocated for each circuit on bootup.
Use 'show voice dsp group all', 'show voice dsp detail', and 'show voice port summary' to get a better idea of what is allocated.
