AIM-VOICE-30 DSPs can only be used for TDM termination on T1/E1. DSP sharing is not available for this module.
Please see the following link for more info: http://www.cisco.com/en/US/docs/ios/12_2t/12_2t8/feature/guide/ft_04gin.html#wp1053375 (notice the dsp allocation can be shared when using a T1/E1 packet voice network module; not the AIM dsps) Thank you.

An AIM-VOICE-30 was supposed to provide DSPs to vwic-2mft-e1 and vwic-2mft-t1. The problem is I cant create the second pri-group. The first pri-group was created successfully. When I create the second pri-group, it failed with following error prompt: % Not enough DSP resources available to configure pri-group on controller T1 0/2 % The remaining dsp resources are enough for 28 time slots. % For current codec complexity, 0 extra dsp(s) are required to create this voice port. I guess AIM-VOICE-30 don't support DSPs sharing. Once it was assigned to e1 or t1, the remaining DSPs cant be assigned to another t1 or e1. But previous email in this list, someone posted lab equipment list that AIM-VOICE-30 is the DSP resources for both E1 and T1. Did I get wrong understanding? Any response would be much appreciated :) Cheers, Allan _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
