I know the DKSC16 has DTMF receivers and the OPC card gives you the option to add more, but what about T1/E1 Cards - how is DTMF conversion done on them?

I have a predictive dialer system connected to my Inter-tel Axxess system via a T1/E1 card. The predictive dialer is a PC with some dialogic T1 cards in it. The T1 channels are just OPX extensions in the Axxess phone system. Dials are initiated on thes OPX extensions using DTMF tones. Are there any known limitations on the Axxess and/or T1/E1 cards in regards to listening/converting DTMF tones? If I have 96 channels of dials all DTMF would that generate an error or overwhelm the system? It would be rare that all of these channels would be DTMF dialing at once. They dial, and then listen to do call progress analysis.

I'm just trying to find potential bottlenecks before they occur.

Thanks.
