What does a CMTS do?
(Cable Modem Termination System) A computer-based device that enables cable modems to send and receive packets over the Internet. It inserts IP packets from the Internet into MPEG frames and transmits them to the cable modems via an RF signal.
What is the difference between MoCa and DOCSIS?
MoCa allows for multimedia sharing between media equipment in the house without internet, A Docsis modem is a type of internet protocol/design and is more about how the modem connects to RF frequencies to achieve upload and download speeds.
What connection technology uses CMTS?
Which connection technology uses what is known as a CMTS? The Cable Modem Termination System (CMTS) connects lots of different cable connections to an ISPs core network. An IT suspects that an unauthorized device is connected to a wireless network. This is a result of passkey sharing on a device brought from home.
How do modems communicate data?
A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a electrical signal that can be transmitted easily and decoded reliably.
What are DOCSIS devices?
DOCSIS stands for Data Over Cable Service Interface Specification. It is an international telecommunications standard the addition of high-bandwidth data transfer to an existing coaxial cable TV system. This is an important feature to know because it influences which modem you get for a cable Internet connection.
Does MoCA work with docsis?
The SCTE/ISBE and the Multimedia over Coax Alliance have issued a “standards operational practice” aimed at ensuring interoperability between MoCA 2.0 and DOCSIS 3.1, which can both live in frequencies above 1 GHz.
What frequency does MoCA use?
The Multimedia over Coax Alliance (MoCA) defines specifications that allow the distribution of multimedia and data over existing coaxial cable infrastructures. MoCA uses 50 MHz channels in the 850 MHz to 1500 MHz frequency range.
Is DOCSIS hardware or software?
DOCSIS technology works with both hardware, and software which enable internet connectivity. They feature the MAC (Media Access Control) layer and the PHY (Physical) Layer.
What is the difference between CMTS and DOCSIS?
(2) CMTS -> It stands for cable modem termination system and it is located at the cable operators end (also known as head-end) and connected to Internet. A DOCSIS network provides bi-directional flow of IP data between cable modem and CMTS over hybrid-fiber/coax cable systems NOTE : DOCSIS has two variants.
What are the components of DOCSIS?
If we talk about DOCSIS network then there are two major components in this system : (1) CM-> It stands for cable modem and it is located at subscriber end. Various devices like PC, laptop, phone etc can be connected to it.
What is a basic DOCSIS architecture?
As can be seen from the image above, a basic DOCSIS architecture contains : A cable modem termination system (CMTS) at the cable operator end (also known as head-end). Cable modem (CM) which is located at the subscribers end. CM and CMTS communication over HFC cables.
What is a DOCSIS network?
A DOCSIS network provides bi-directional flow of IP data between cable modem and CMTS over hybrid-fiber/coax cable systems NOTE : DOCSIS has two variants. There is a European version on DOCSIS known as EURODOCSIS. While American version is known as simply DOCSIS.
