I am going to buy either the 1751 or 1760 routers but I noticed that there are different versions of the routers. Do I need a 1751-V or 1760-V if all I am looking for is to add a VWIC-2MFT-T1 card? I am looking at table 2 of the differences and the big thing I noticed are the DSP. From what I know DSP (Digital Signal Processor) converts Analog to digital but is this required for a T1 card since T1 is digital anyway?
Any place beside ebay where I can get a great deal on a Cisco 1751 or 1761 would be greatly appreciated.
