Dear l,

Yes you could but I question if the cable and ends you have are the correct type.

There are two factors here:
1. Typically the connection from a broadband modem to a PC is a LAN connection and should operate at 100BaseT. For this the cable should be rated as category 5 or higher.
2. The connectors you have should also be rated at category 5 or higher and the internal pins must be made to match the conductor construction of the cable (solid or stranded and also match the AWG).

Provided that all the above is verified the pin-outs for a 100BaseT cable are paired as pins 1 & 2, 3 & 6 and is the equivelent of pairs 2 & 3 in a T568A or T568B wiring scheme. See the pinouts on this site for the exact reccommended color coding at
