docsis

Broadband wireless access technology is worth learning a lot. Here we mainly introduce the DOCSIS-based broadband wireless access technology, from the DOCSIS Protocol release to the current development trend, many related equipment manufacturers use DOCSIS Protocol in their 3.5 GHz MMDS products because DOCSIS uses man

Viewing a DOCSIS configuration file requires a specialized tool. Tool installation Under Windows, you can use the tool vultureware DOCSIS Config Editor.Under Ubuntu (native version 12.04), you can use the Open source project Docsis Project 's docsis Tools ( home page here ).Its code was previously in Http

of the system is composed of wireless base station equipment (WMTS), wireless client equipment (WMU) and network management system (NMS. A typical GHz broadband wireless access system consists of multiple base stations, hundreds of user-side devices, and a unified network management system. In order to improve the spectrum utilization of the gold GHz band and expand the system capacity, the macro-cell adopts sector segmentation (optional sector angle), band refinement, and same-frequency multip

access system consists of multiple base stations, hundreds of user-side devices, and a unified network management system. In order to improve the spectrum utilization of the gold GHz band and expand the system capacity, the macro-cell adopts sector segmentation (optional sector angle), band refinement, and same-frequency multiplexing. Dynamic Power Control, antenna polarization, and frequency planning are used to overcome interference between different base stations and sectors. Optional values

selection technology, which currently accounts for more than 40% of the double-reform market share. • EPON + C-DOCSIS: national standard technology, for China Radio and Television Network, compatible with the original CMTS system. • FTTH: it is still pilot and the CATV access method is unclear. In the FTTH solution, CATV access is divided into three types: Single-fiber three-wave, dual-Fiber Three-wave, and fiber-optic Coaxial Dual-household. Because

Cable TV Cable (Cable) mode broadband access to the Internet is the standard docsis (Data over Cable Service Interface specification), Recently this standard has been upgraded to 2.0, and Imedia announced in April the DOCSIS2.0 chip IM6030 and a reference design that can be mass-produced immediately. This means that the new cable cat and head-end equipment will be on the market time greatly accelerated, the cost can guarantee a lower level, which is c

transmission performance and provide strong support for resource critical applications such as multicast and VoIP. Scalability and flexibility. The data transmission on the downlink channel is completed by different independent templates, and its proportional relationship can be flexibly and arbitrarily configured. Multifunctional Both one-way cable transmission (telco-return) and two-way cable transmission can be implemented in one rack without additional remote dial-up devices. Standard se

Specification entity (entityspecification) defines a certain type of entity; Characteristicspecification defines attributes of one or more types of entities; Characteristicspecvalue defines the possible values of feature types; You can define attributes for productspecification, product, and customer. So how can we apply Sid's "Specification mode" and "feature mode?2. Introduction of specification mode and feature Mode The following uses the most common product display page of an e-commerce

-level services by 21% over the past year and a half, while optical fiber increased by 15% and ADSL by 17%. DSL and cable enterprises have developed new technologies, such as adsl2 + and DOCSIS 3.0, to improve network speed. In contrast, fiber development lacks new capabilities. The reason is that optical fiber has advantages, so it is not worried about threats from ADSL and cable. However, the disadvantage of optical fiber is that the deployment cost

standard of data transmission in HFC is DOCSIS, which is made up by the forum MCNs of the major manufacturers in the industry. Compliance with standards and CABLELAB-certified equipment ensures interoperability. The performance of HFC network constructed in different periods is different, the network with early construction does not have the ability of uplink return, so it needs to be reformed to implement bidirectional transmission. For the one-way

four access methods are selected based on the user's actual network conditions. By using MTA or IAD, you can access OCs through interfaces RJ45 and ipv11, the local terminal accesses the Bearer Network of the NGN user access technical network through the access layer device cmts of the HFCs network. In this way, the HFCs broadband data access network is used as a pure access network, make full use of the existing market users who have already activated the broadband access service for the radio

the upper-level NCP protocol (also known as IPCP): Responsible for IP address settings and whether TCP/IP header compression and other settings. 19, ATM is a unit called cell transmission of the data link, due to its short line occupancy time and the ability to efficiently transfer large-capacity data and other characteristics are mainly used for wide-area network connection.20, Aym so far the biggest drawback: even if only one cell error should be discarded all packets, to re-send.21.

The following is an example of how to use 802.11 GB for data and video distribution in a typical home environment. In this example, there are two floors in the home: a TV and a digital set-top box (STB) in the living room on the first floor, and a laptop in the Home Office; one bedroom on the second floor has a TV Plus STB, and another room has a desktop computer. The digital STB in the livin

A firewall with VPN protection can protect sensitive data of remote sites and prevent DoS attacks from these computers. VPN and SSL provide security methods for e-commerce transactions. PGP and PKI can be used based on business needs. ◆ Modem security: Sometimes the configuration and verification information of the modem are stored on it, and some ar

This plug-in is very convenient to install and switch ruby versions. It is strongly recommended that the ruby version of the Mac system is outdated. Therefore, you need a tool to manage it and install RVM. Bash and git are required. The installation of these two tools is very simple. Run the following command to install RVM: Bash Then modify the user configuration file/Users/username/. profile. You can also write it to other global configurations. Add a line of code: Code highlighting prod
