From what I'm hearing, it's sounds to me like there might be some energy moving through the wire but not enough to allow a "true" connection. How bytes or "packets", move from the NIC to NIC is such that if a "packet" gets corrupt (bad line ect.) the NIC automatically sends it back to the router for retransmission. But, it sounds like you just got some crazy packet loss on that particualar line. So...to answer your question, No, a computer on the same network as the faulty line would not be effected. The only thing that might happen is that, if you had file sharing enabled(or a mapped network drive), it would not be able to map to it. Hope this helps.
