Are you looking for reliable cable and internet providers to connect your home? Teleful Connect works with leading providers across the US, so we can help you find the best deals and bundles. Many homes get their internet services from the same company that provides cable TV. Cable internet leverages the cable TV infrastructure to offer high-speed connections to your home. Most of our providers bundle internet access with TV channels.

What You Need for Cable and Internet Service

For cable and internet services to work, you need a service provider and specific infrastructure; modem, coaxial wires/cables, and CMTS. The provider will set up a cable box to convert the digital signals to analog. A modem inside your house connects to the coaxial cables that run to the cable modem termination system (CMTS). The internet service provider houses the CMTS within its premises. Here's more about what you need for cable internet services:

1.    The Cable Modem

A cable modem is a small box installed inside your house. The device facilitates communication between the cable service provider's system, your PC, and other connected devices. Most providers we work with at Teleful Connect offer modems together with routers as part of the package. The router allows you to connect multiple gadgets to the internet. A cable modem enables broadband internet and cable TV services.

Every subscriber has a unique registered cable modem. You can rent one from your provider and pay monthly or purchase your own to avoid such fees. If you buy a cable modem, the cable TV and internet provider will request the serial number and machine access code (MAC) address to register the hardware. Teleful Connect works with popular cable network providers, including Comcast, Cox, Cable One, RCN, and others.

Typical cable modems have coaxial RF (radio frequency) input ports and RJ 45 output ports. A coaxial cable from the CMTS is plugged into the RF input port, while a CAT 6 cable is attached to the RJ 45 output port. The CAT 6 cable from RJ 45 output goes into your router, which delivers the internet service to other devices, like your PC, laptop, tablet, and smartphone. You can connect a PC directly to the cable modem RJ 45 using a CAT 6 cable.

2.    CMTS (Cable Modem Termination System)

A cable modem termination system refers to a piece of hardware owned by your cable internet provider. The hardware resides within the provider's site/facility and communicates with the cable modem in your house. You can only access cable internet when the CMTS effectively communicates with your modem. The CMTS exchanges digital signals with the modem over the cable network.

Cable TV and internet providers deliver services to subscribers through channels found in coaxial cable or optical fiber cables. One cable sends downstream signals from the CMTS to your modem, while another sends upstream signals from the modem back to the CMTS. When a cable modem sends upstream signals, the CMTS converts the signals to IP packets and routes them to the internet provider for transmission across the internet.

Two main types of CMTS architects exist: Integrated (I-CMTS) and modular (M-CMTS). Integrated CMTS architects feature all components under a single chassis, which reduces points of failure and lowers deployment costs. Modular CMTS involves using multiple chassis, which can make it easier to scale to huge numbers of downstream channels. CMTSs modulate downstream signals transmitted across coaxial cables to the modem installed in your home.

3.    Cable Box (STB)

A cable box originally referred to the metal enclosure located in the vicinity of your home. The box connected your house or building to the cable provider and indicated where the provider’s cabling responsibilities end. Providers use cable boxes to direct their services to the wiring inside your house and control the channels based on your subscriptions. Cable boxes evolved into the set-top box (STB), which sat on top of analog TVs to scramble TV channels.

The STB could sit on any flat surface and convert digital signals to analog. STBs have evolved into modern boxes, including satellite receivers and media hubs like Apple TV, Fire TV, Roku, and Android TV. Modern-day cable set-top boxes decode MPEG video frames and decrypt premium TV channels. They store program guides and displays while providing upstream signals for video on demand. Cable boxes record content on their built-in DVR hard drive.

The coaxial cable from the cable TV and internet provider is split into two channels using a splitter. One line goes to the cable modem, while the other goes to the STB. The channel to the cable modem carries internet signals, while the one to the STB is specifically for TV channels. A typical set-top box has a power on/off switch, a coaxial input port, HDMI cable output that goes to your television, and a power cable.

4.    Coaxial Cables

A coaxial cable or coax is a special wire you need to connect the cable internet provider’s system to your in-house hardware. Coaxial wires or cables allow the transmission of data over long distances and are located underground or in overhead channels. The lines connect the CMTS to your cable modem and STB. Coax wires carry data, video, and voice communications. They are the choice cable for telephone companies and cable and internet providers.

Coaxial cables emerged in the early 20th century, and the infrastructure spans more acres than any other cable connection. Fiber optic cables are expected to replace coax cables because they use glass fiber and offer super speeds. They’re not available in some areas, which is the main drawback. Coaxial cables cover most of the country. The most used coax cable sizes include RG-6, RG-11, and RG-59, where RG stands for radio guide.
