Cisco 1750

[UNIX72]

What is the difference between the 1750 and 1751 (17502v) routers? Will the 1750 support voice FXS or FXO cards out of the box(besides IOS upgrades) or do I need a 17502v or 4v router. When i look at the cisco site its refering to DSP module with the 1750. What is DSP? Will the 1750 work with voice? Thanks

If I'm not wrong DSP means Digital Signal Processing
