随着数字通讯技术的不断发展,宽带高速的接入设备不断涌现。模拟调制解调器被一些人形容成“老牛拉破车”,早该被淘汰了。我感觉这种说法未免有点片面。新技术新产品的出现固然会给我们带来更高的速度,更多的空间,但是它需要一个普及的过程,需要众多服务商利用新技术提供更为丰富的服务,这正是通讯产品的特点。显然,普及的过程需要大量资金的投入,服务不可能在短时间内就变得丰富多采,然而在这段时间内用户即便只想获得有限的服务,也要付 With the continuous development of digital communication technology, broadband high-speed access devices continue to emerge. Analog modems are described by some as “Old Bull pull broken car”, should have been eliminated. I feel this statement is a bit one-sided. The emergence of new technologies and new products will certainly bring us higher speed and more space, but it requires a universal process, requiring many service providers to use new technologies to provide richer services, which is the communication products Features. Obviously, the process of popularization requires a lot of capital investment, services can not become rich in a short time, but in this period of time even if users only want limited access to services
