Hello,
I have an old IAD2421-8FXS and I believe that the DSP module is going bad because calls to and from the FXS ports are coming back with broken voice and low volume. Does anyone know where I may find a replacement DSP card.
Sincerely
-Jeff

Jeff,
The IAD-2421 is End Of Life/End Of Support as of July 2009:

The DSP's aren't FRU parts anyways, IAD is a modular unit and the DSP's aren't an orderable part...even if it still had HW support.
For testing, the syntax for removing a suspect DSP from service is:
router# test dsp device 0
This places the DSP in a "bad" state, then save, reset the IAD.
In this case you'd most likely want to take DSP 1 out of service, since you only have 8 FXS ports.

Dave,
Thanks for the suggestions. I did as you instructed and verified with a "show voice dsp" to ensure the DSP's were in a bad state, and it turns out that after making a test call, alternating with each DSP down, that they are both bad. The audio was still choppy, so I am assuming that I got myself I nice new door stop. Ha ha. Thank you very much for the suggestions, now I know how to test these routers in the future.
Sincerely
-Jeff
