[USR-TC] connection type

I am placing my 3com TC 1000 at telco. Few E1 lines will be connected to TC then from tc I need to connect to a DSL modem which will connect to my ISP. How can i connect my TC to DSL ?? are there any spcial cards for TC ? Can i use the WAN port on TC (rj45) ? The DSL will have v.24 or v.25 or g703 connection type. __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
