我们使用的调制解调器速率从可怜的2400bps发展到33.6Kbps似乎一直是一帆风顺,但在56Kbps时出现了x2和K56flex的制式之争。在去年九月份,问题终于得到了解决,V.90协议统一了这两种互不兼容的通信协议,驱散了笼罩在高速调制解调器制式上的迷雾。 我们现在在市场上可以购买到的56K调制解调器全部支持V.90协议,但这并不说明它们的内部芯片是同一结构。56K调 The modems we used to go from a poor 2400bps to 33.6Kbps seemed to be going smoothly, but at 56Kbps there was a battle between the x2 and the K56flex. In September last year, the problem was finally solved. The V.90 agreement unifies these two mutually incompatible communications protocols and disperses the fog that has lain the high-speed modem system. The 56K modem we are currently available on the market all fully supports the V.90 protocol, but that does not mean that their internal chips are the same. 56K tune
