Sort of. It can handle it's own DTMF transmitting
if the system flag
Enable T1/E1/PRI DTMF Dialing is set to yes, otherwise it defers to the PCMA. But it cannot receive DTMF. For that it defers to CPU's, OPC's & DKSC16+ cards.
With 3 ATM subnodes, you have 18 receivers between the PCMA's alone. Add to it 36 across the OPC's and 4 more per DKSC16+. That's around 102 receivers in all based on 12 DKSC16+'s. If you add the fourth subnode then you can add 6 mode.
This is a subjective statement to labor over: I'm just trying to find potential bottlenecks before they occur.
Basically you're looking good in my eyes. DTMF receivers are only in use for the amount of time needed to process the DTMF, then they are released. What I don't know is the channel allocation strategy you've used to mitigate blocking. These are shared resources which can be "borrowed" from an idle resource on another subnode if all of them are in use locally. Plan your card configuration wisely.
