Unable to Add Extra PRI on Cisco 3945 - Resource Unavailable

Hi,

I not able to add more than two PRI's on my Cisco 3945 Gateway. As you can see in the below attached the configuration file the third controller is partially registered. Also you can see that both the transcoder and conference profiles are shut down and I have PVDM3 with 192 channels.

Please go through the configuration file attached. Do let me know if you need any further information.

Looking forward for your thoughts on the same.

Thank you.

Joseph,

You dont have enough DSPs for your combination. This may sound strange but you need to understand how DSP allocation works for this to make sense...

1. You have PVDM3-192..This contains a total of 5 dsps in a combination of PVDM3-128 and PVDM3-64

1. EVM-HD modules do no support dsp sharing because it supports online insertion and replacement

. You have 3 EVM-HD modules, the gateway alocates 1 dsp for each of them. Thats a total of 3 dsps.

2. You have enabled a total of 75 channels (30+30+15) on your PRI configuration. The remaining DSPs have then been allocated for this.

Your conferencing and transcoding do not have any impact because you have not define any sessions on them. So you will need to ad dmore DSPs to enable additional PRI slots
