The hub or repeater simply repeats an incoming signal on all ports and also sends the jam signal to all ports if there’s a collision.
简单来说，中继器将正常情况下收到的信号，和数据碰撞时产生的拥塞信号重复发送到所有的端口。
The radio signal was sent out in a special way so that no one was able to jam it.
这种无线电信号是用一种特殊的方式发送的，所以无法对它进行干扰。
Just to make sure that the source of the interfering transmission also detects a collision, upon detecting a collision, a station sends a "jam" signal for 32 bit times.
为了确保发送干涉信息的源头也能知晓发生了数据碰撞，发射站在检测到碰撞后，要发一个是32比特的倍数的拥塞信号。
