Cable modem termination system. A cable modem termination system (CMTS, also called a CMTS Edge Router) [1] is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide data services, such as cable Internet or Voice over IP, to cable subscribers.
Provide cable service operators with service protection (i.e. prevent unauthorized modems and users from gaining access to the network's RF MAC services) BPI/SEC is intended to prevent cable users from listening to each other. It does this by encrypting data flows between the CMTS and the cable modem.
Example of a cable modem installed in a home office. A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fiber-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure.
In the cable modem termination system (CMTS) industry, there are two main types of CMTS: virtual CMTS and traditional CMTS. Because virtual CMTS is economical and energy-efficient, end users are starting to use it. Small cable operators are in great demand for little cable modem systems because they provide an alternative to bigger, more costly ...
The Arris Surfboard S33 is a DOCSIS 3.1 device with a 2.5 Gbps Ethernet port that supports all major cable providers. Plus, it sports a second 1 Gbps Ethernet port you can use for a separate network.
One downstream channel can handle hundreds of cable modems. As the system grows, the CMTS can be upgraded with more downstream and upstream ports, and grouped into hub CMTSs for efficient management. Most DOCSIS cable modems restrict upload and download rates, with customizable limits.
In Remote PHY, equipment such as CMTSs or CCAPs are connected directly to the HFC network using fiber optics carrying digital signals, eliminating the RF interface and coaxial cables at the CMTS/CCAP and RF modulation at the headend, [83] and replacing analog signals in fiber optic cables in the network, with digital signals such as 10 Gigabit ...
It makes the EPON OLT look and act like a DOCSIS Cable Modem Termination Systems (CMTS) platform (which is called a DPoE System in DPoE terminology). In addition to offering the same IP service capabilities as a CMTS, DPoE supports Metro Ethernet Forum (MEF) 9 and 14 services for the delivery of Ethernet services for business customers.
