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

policy management and access control capabilities management, and remote configuration and troubleshooting capabilities.The main transmission medium of the-----cable system is a bidirectional HFC network, which is mainly composed of two-way amplifier modules such as the positive and negative optical transceiver of the optical fiber network and the coaxial cable network.-----in the first phase, it is planned to configure the head-end devices (CMTS) of

advantage is that the time slot allocation is fixed, which facilitates adjustment and control and is suitable for the transmission of digital information. The disadvantage is that when a signal source does not transmit data, the corresponding channel will be idle, other busy channels cannot occupy this idle channel, which reduces the utilization of the line. The time division multiplexing technology, like the frequency division multiplexing technology, is widely used. telephones are the most cl

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 activat

gate no problem.Built-in memory, can achieve 21M single-and dual-port RAM,ROM,FIFO, and so on, if the ASIC uses a little more storage, you can also use the Lut to implement some of the storage, instead of block RAM.If more multiplication is used, you can also map the implementation of DSP devices in the FPGA, the specific types of FPGA contains how many devices, you can refer to the Xilinx documentation.For the built-in IP, the first thing to consider is the clock module MMCM, the general FPGA

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
