简介：这次在线座谈重点介绍ST公司的ADSL+ VoIP解决方案的性能和芯片组等丰富多彩的内容.采用ADSL+ VoIP解决方案不仅会使您宽带接入到互联网,体验宽带网络所带来的乐趣,而且还能利用互联网进行通话,大大节省通话成本.

问：能否提供VoIP+ADSL解决方案的参考设计资料?
答： Yes. Please contact with our local contact marketing: helen.liu@st.com

问：如果在ADSL（softvoip）只支持1个语音通道的话，那么这个产品只能在家庭用户市场上做了，在中国家庭市场规模虽然很大，但是消费能力不是很大特别是在在固话通讯消费上，如果产品的价格定的很高的话，会给运营商很大的压力，一般运营商普遍采用送设备给家庭用户，比如目前中国电信ADSL用户，他们的设备基本有运营商来送的，你们是否考虑到这个问题呢？
答： The next generation ADSL chipset will support more channels.

问：如何实现在这个平台上支持多路语音？
答： Multiple channels will be supported in the next gen ADSL chipset.

问：The cost of chips used in this solution seems expensive.Do you think this solution will attract customers?
答： This solution is competitive compared to competitors.

问：Is the 5093 using any DSP core?
答： NO. It is just a sampling codec.

问：请问：正是由于这种解决方案导致CPU资源的紧张，所以才没有支持ADSL2+吗？那么在下一代可以支持ADSL2+的产品中将如何解决这个问题？
答： It is because of the current ADSL DMT engine only supports ADSL.
The next generation DMT will support ADSL2+.

问：VOIP的保密性如何？
答： There is H.235 security in H.323. There is MD5 and S/MIME support in SIP. And for MGCP it mainly relies on the lower layer protocols for security but in China there are existing proprietary authentication mechanisms existing.
There is also secured RTP

问：解决方案中，哪些是要收费的？
答： Do you mean the software?
ST has a quotation for the provided software including protocol stacks and dsp codec.
For compressed, a seperate license fee has to be paid to standard committee.

问：整合以后有什么优点？能否提高带宽使用效率？
答： The combined voice+adsl does help the consumer to maximise the DSL bandwidth available to them.

问：能举例说一下你们的ADSL+VOIP主要用在什么方面吗？
答： The focused market is very broad.
