Re: Jam signals

A jam signal is part of the Etherent CSMA/CD standard. Basically a station that sees a collision during transmission continues to transmit called "a jam signal" for a period of time to ensure that the propergation delay timer is met so that all stations on the collision domain see the segment is active/busy and reset their timers to wait/listen for quite/idle before they next transmit.
