distance. This technology is the Ethernet over the telephone line. VDSL signals are transmitted at the physical layer and Ethernet signals are transmitted at the second layer. It can extend the transmission distance from the original 100 meters to up to 5 kilometers, which is especially suitable for the city range and the speed remains unchanged. Any cable can be supported, greatly facilitating the application. System Development From the perspective

, but also supports rich value-added application development. In addition, as some switches start to directly connect to the WAN, more and more switches have some routing functions. Considering the large-scale application of next-generation Internet Protocol IPv6 in the future, Cisco's next-generation switch also supports IPv6 hardware. Ethernet is constantly expanding its coverage and is evolving towards wireless and long distance. Cisco provides users with a comprehensive wireless network solu

To learn more about router Internet access configuration, it is very important for ordinary home users and to ensure our network security. The first thing to confirm is what your "Broadband Access Method" is like? Of course, the simplest way is to call your ISP (Internet Service Provider) for consultation. You can also make a quick judgment by using the network connection method you used to buy a router. Common Hardware connection methods include the following: 1. Telephone Line> adsl modem> Com

. You can also make a quick judgment by using the previous network connection method of the router you purchased. Common Hardware connection methods include the following: 1) Telephone Line> adsl modem> Computer 2), twisted pair ethernet cable)-> Computer 3), Cable TV coaxial Cable)-> Cable MODEM-> Computer 4), optical fiber-> photoelectric converter-> Proxy Server-> PC ADSL/VDSL PPPoE: A computer runs a third-party dialing software such as Enternet30

sell 60000 sets in the next three years. For a long time, NEC has been using the "AM31 series" product of the ADSL multiplexing equipment and the "AM3100 series" product of the MSAN (Multi Service Access Node) device through the sales Bureau, it has contributed to the broadband implementation of fixed-line communication in overseas markets. At the same time, they also enjoy high praise in Japan and are praised for their high quality and stability. At present, they have achieved more than 7 mill

In recent years, with the development of the communication industry, the number of Internet access methods has also increased. Here we mainly introduce the most widely used PSTN dialing methods, including the introduction of ADSL. When it comes to access networks, we must first involve a bandwidth problem. With the continuous development and improvement of Internet technology, the bandwidth of access networks is divided into narrowband and broadband. Industry experts generally think that broadba

Open IE browser and enter the gateway address of the wireless router in the address bar. For example, 192.168.1.1 or 192.168.0.1 vro has different addresses. For details, refer to the vro manual.) After you enter the password, the management interface of the wireless router appears. In the management interface, find "WAN port settings or WAN port connection type" and other similar options. If the bandwidth is leased line access, select the static IP address mode and enter the password; for ADSL

licensed spectrum, depending on your needs for service levels, the maximum transmission distance of WiMAX is 31 miles. WiMAX and Wi-Fi, 3G, and DSL will coexist in a long period of time, and compete with each other in the overlap area to a certain extent. I. WiMAX and DSL XDSL can be divided into symmetric rate and asymmetric rate based on the same upstream and downstream speeds. XDSL with symmetric rate has multiple forms, including IDSL, HDSL, SDSL (SinglelineDSL), and HDSL2. Asymmetric xDSL

+ VDSL technology, therefore, in order to make up for the insufficient optical fiber resources at the aggregation layer and ease the bandwidth pressure on the aggregation layer, the access layer and end user links are specially configured. In the construction of the core layer of the Area Network, the 144-core optical fiber cable is used as the transmission line, and two backbone IP data node routers are deployed ). At present, there are still surplu

software optimization of computers in the future can become the driving force for the Network to fly. On the one hand, the system's own performance can be improved through a number of "extensive" system optimization software, such as the CPU vacancy rate, memory usage, and hard disk fragment cleaning, can be improved through the power of software. On the other hand, some special software can also be used to optimize the broadband access connection network and randomly adjust some network connec

equipment is still troublesome. At present, a lightweight and non-sharded ADSL is developed. The basic idea is to reduce the speed to around 1.5 Mb/s, and to avoid telephone sharding for users, in this way, the price may decrease and the installation is more convenient. However, the interference problem, especially the interference problem with the conversation, needs to be properly solved. The development of lightweight ADSL has been supported by all walks of life, and its application prospect
