specifications are added for the LMDS/MMDS market. These extensions will be included in a new standard or an extension of the existing DOCSIS standard), which is currently being studied by the IEEE 16th Committee. At present, the market has launched a DOCSIS-based wireless access system. However, how to ensure real-time business and reliable application in the wireless environment requires further lab veri

equipment CMTS. Cable TV network is one-way, can take two kinds of solution. One is a two-way network transformation, through the transformation of some lines and distributors, amplifiers, etc. to make the network into two-way network. Another way is to use the existing telephone network, the downlink channel is still unchanged, and the telephone dial-up channel as the uplink channel. From the standpoint of serving the user, it would be preferable t

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 a single-fiber three-wave adds one WDM module per household,

Talking about Cable Modem broadband access technology and its maintenance when talking about Cable Modem broadband access technology and its maintenance, we need to first understand what Cable Modem?1 Cable Modem the concept Cable Modem is also known as a Cable Modem. It is a terminal device for high-speed data access through the hfc-cable TV network. It consists of a tuner, interpreter, pulse modulated device, processor, and interface. After the Cable Modem is installed on the user end, it can

redundant lines in the cat-5e to take advantage of the four wires 1/2/3/6) and a gossip 11 port using 4/5 of the two lines) to achieve simultaneous access to the PC and POTS in the user's home. The above 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

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: 7 MHz, 3.5 MHz, and 1.75MHz. Optional values: 3.2 MHz, 1.6 MHz, 800 KHz, 400 KHz, and KHz. The broadb

technology, like the frequency division multiplexing technology, is widely used. telephones are the most classic examples. In addition, the time division multiplexing technology has also been widely used in radio and television, for example, SDH, ATM, IP, and the communication between CM and cmts in the hfcnetwork is based on the time-division multiplexing technology. 3.

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

The general ASIC will contain multiple clock domains, eac

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 is too high. Hybrid methods have become a method for enterprises to build networks. British Virgin Me
