7. Let’s take a look under the hood?

8. What are those resources?

9. Now let’s look under the hood?

10. What are the differences?

11. TDM call control Media processing Switch control PCI H.100 PCI card API talks to ‘native’ card driver and card over PCI Current generation card TDM call control Media processing Switch control PCI H.100 PCI card API talks to ‘native’ card driver and card over PCI 10/100 BASE-T Ethernet
