What is the end of the cable modem?
Cable modem ending system (CMTS) is a device used in a cable network to communicate with cable modems using a digital signal. It is usually located in the head cable head, which is the main center to which all cable signals for Internet operation and cable TV are sent and are accepted from customers. Cable modems cannot communicate directly and must pass through the cable modem ending system.
The main purpose of the Cable modem end system is to act as a translator. Usually, the cable provider's head is located where the signals for cable TV or the Internet are sent to the user. The main end is where the cable modem ends system, as well as devices that receive various signals, such as an Internet connection and satellites for television signals. Cables used to connect to subscribers are the same for internet and television operation, but the end of the cable modem usually only afterIt uses one or two channels to communicate with cable modems.
The typical end of the cable modem is set to have several interfaces, just like the router. Basic CMTSS will have an Ethernet connection at one end, a type used to transmit the Internet protocol (IP) and radio frequency connectors (RF) at the other end. The signal comes from the Internet in IP packets, passes through the cable modem system and then from the RF connector. RF signals are then routed via the hybrid fiber cable (HFC) to the subscriber cable modem.
Subsequent operation or operation, which is directed by means of a cable modem system to the cable modem, is the same IP protocol that is used on the Internet, but is encapsulated in another special type of packet that is modulated to travel at the frequency of cable television. When transfer comes from a cable modem to cable modemusystemThe termination, called upstream operation, is encapsulated in another type of packet, which is at a lower frequency range than downstream packets. Operation from television satellites is not directed through CMTS because it only carries the operation of IP.
In addition to providing a way to direct internet traffic, the system will offer the end of the cable modem another service for the participant. At least it will direct the operation of the dynamic configuration protocol of the host configuration (DHCP), which is a protocol used to obtain an IP address and other relevant information. It can also provide certain security, blocking potential attacks and other unauthorized operation.
