ADSL虽然作为最后一公里问题的解决很有前景，但它的性能从未达到它的理论值，不知是否是原理上的缺陷；贵公司的产品是否对此有了很好的改进 |
| [答：LeeKL] |
ADSL is able to reach connection rate of 8Mbps up to over 8kft. For
ethernet for the first mile where the throughput requirement is higher,
VDSL is the solution. ST have the VDSL solution based on DMT, ready to be
in the market soon. |

我的实验室里有四十台计算机，请问用ST的CPE
ADSL速度怎样？ |
| [答：Danny] |
我们没有做过实际的测试，但是我们的芯片硬件支持64个MAC
address.我们的Firmware中的DHCP能分配超过40个ip地址。理论上支持40个用户是没有问题的。但是具体的速度除了我们的modem外，ISP提供多大的带宽给你们也是一个因素。我们的下一代产品50180中除了支持ADSL+2外（下行到16M,上行达到2M)，嵌入的ARM
CPU 有更快的速度，将可以支持更多的用户。 |

请问﹐modem在播号过程中波型是怎样变化的?无播号音但可以成功连接是什么回事?谢谢﹗ |
| [答：LeeKL] |
ST ADSL uses DMT (discrete multi tone) technology. When
power up, CPE modem will send the activation tone to the
line. When CO (Central Office) modem detects the activation
tone, both CPE and CO modem will start the initialisation (line adaptation
training) to decide the optimum connection rate. |
