Is it okay if I use Cisco 1751 with WIC 2T for an E1 connection coming from ISP? The 1751 will be used for routing IP packets only..... thanks
 
Yes the WIC-2T can terminate an E1 if the telco provider can provide an X21 termination for you.
 
thanks for the information, will the 1751 choke/hang if the full E1 has been utilized?
 
Shouldn't be a problem. According to a Cisco fact sheet I have here, the 1751 can deliver the following throughput rates:

Process switching: 1500 packets per second (768 Kbps)
Fast switching: 12000 packets per second (6.14Mbps)

The above figures are based on 64k packets which always offer the lowest throughput, i.e. these figures are absolute worst-case. In reality, you will get very random packet sizes and should see considerably better throughput than the figures above.
