Second, the standard of communication industry, the strength of enterprises want to become the standard leader. With other industries before the application of the standard is different, the communications industry is to determine the standard to ensure interoperability between equipment. And each generation of mobile communication stand

Another aspect of Web voice development is the progress of VoiceXML (Voice extensible Markup language-Speech Extensible Markup Language). The main goal of VoiceXML is to make the interactive voice interface fully enjoyable with the extensive application and rich content that is already on the web. The Web server handles a request from a client application, which is handled by the VoiceXML interpreter and the VoiceXML

USB2.0 technical specifications are by Compaq, Hewlett Packard, Intel, Lucent, Microsoft, NEC, Philips jointly developed and released, the specification of peripheral data transmission speed to 480Mbps, is a USB 1.1 Device 40 times times! But as planned, the new USB 2.0 standard is just about to set the standard at 240Mbps, and then, after a while, to improve it to 480Mbps.
As a result of the changes made at that time, the USB specification pr

Ethernet technology for transmission. Regardless of the method chosen, the growth rate of IP services running on real Ethernet or SONET is growing rapidly. It is noteworthy that with the establishment of the 802.3AE 10G Ethernet standard, Ethernet can digest the entire OC signal for the first time without wasting bandwidth. The transfer of G-bit Ethernet on OC-48 (2.4GB/S) can be very inefficient because there is always unused bandwidth in the signal. 10G Ethernet can greatly improve transmissi
(Fiber Distributed Data Interface/twisted-pair distributed Data Interface), the emergence, application, promotion and development of building automation system, the original wiring system will not meet the requirements.
Therefore, to seek a more reasonable, more optimized, flexible, stability and scalability of good wiring technology, has become a top priority. It can not only meet the current requirements, but also the most important is to meet the future of new technologies constantly update
At present, the wireless network solution because of its flexible network, low-cost and other characteristics of small and medium-sized enterprises have been favored users. And will bring huge changes to the small and medium-sized wireless office. Specifically, the successful implementation of WLAN to improve the office efficiency of employees, the company in the scale of expansion, save the time and cost of network expansion, and protect the company's network construction of long-term investmen

As mentioned earlier, this structure is easy to expand and upgrade. Switch products are Cisco 6509/6509 OSR, Foundry bigiron 8000/4000, Extreme black Diamond 6816/6808, Alcatel powerrail 5200/2200, Lucent Cajun P880, Riverstone rs32000/rs8600, Huawei MD5500, Dragon rs6006g/rs6004g, creative AR8000
WiMAX's full name is microwave access to global interoperability (worldwide interoperability for microwave access), combining this technology with the need for authorized or unauthorized microwave equipment, the lower cost, will expand the broadband wireless market, Improve the awareness of business and service providers. WiMAX is the IEEE802.16 standard, or wide band wireless access (broadband Wireless ACCESS,BWA standard). It is a wireless metropolitan area network (WMAN) technology, which is
conducted extensive and in-depth research on OADM devices.
From the commercial level, Lucent Company has developed 40X10GB/S with perfect network interface Oadm node, and successfully to the market. Other companies, such as Alcatel,siemens,nec, also have mature products to launch. At present, the domestic research on OAMD has made great progress, in the 863-300 project "China High-speed Information demonstration network", Datang, Wu-mail, ZTE comple
