Hi,

 

I have Cisco 2821, currently we have pRI circuit terminated on it.

We want to add 8 FXO, let me know if it is possible.

It is possible if you have enough dsp resources. You can calculate hardware need with Cisco DSP calculator - http://www.cisco.com/web/applicat/dsprecal/dsp_calc.html

My question is not related to DSP, it is related to Hardware Chassis of Cisco 2821, does it allow to have 8 FXO, if yes then how?
