I have bought Cisco AS5350XM Voice (PVDM2) High-Density (AS535XM-2T1-V-HC).
There are 2T1 port and two 64-channel DSP modules
My application server uses only G.711(64k) via LAN to talk to AS5350 for inbound IVR calls. If 2T1 is used to full capacity, there should be 82 DSP channels available.
Could I just buy a trunk card (AS535-DFC-4CT1) and use only 3T1 without having to add extra DSP modules?
