I have an 2851 voice gateway router with PVDM2-48 on the motherboard slot, and an NM-HDV2-2T1/E1. When I type:
2851(config)#controller E1 1/0
2851(config-controller)#pri-group timeslots 1-31 service mgcp
I receive this message:
% Not enough DSP resources available to configure pri-group on controller E1 1/0
% The remaining dsp resources are enough for 0 time slots.
% For current codec complexity, 2 extra dsp(s) are required to create this voice port.
Why I cannot activate the port?
Thanks in advance,
Seems like you are enabling a interface on the NM, for that you need DSP in the NM, these on motherboard cannot be used.
However, with ISR router, NM cards are never needed. Just use mpotherboard slots.
