Provisioning occurs when a new modem is initiated/activated. Sometimes configuration issues can come up, and you'll hear tech support say, "We will "reprovision" the modem." Think of it as "resetting" your connection.

CMTS stands for Cable Modem Terminating System. It enables access over the hybrid fiber coaxial network via a cable modem.

An MLS is a multi-layer switch. It interconnects with other network elements at the edge of the network. Multiple CMTS will usually aggregate into a single MLS.

A backbone router is an OSI layer 3 device that connects with other backbone routers to form the complete network backbone. Some backbone routers will connect to backbone routers of other providers (non Cox HSI) as well to "peer" the network. Connection to the internet is provided through a backbone router that interconnects to an Internet provider's network.

Hybrid Fiber Coax is a way of delivering video, voice telephony, data, and other interactive services over coaxial and fiber optic cables.
An HFC network works consists of a headend office, distribution center, fiber nodes, and network interface units.
The headend office receives information such as television signals, Internet packets, and streaming media, then delivers them through a SONET ring to distibution centers. The distribution centers then send the signals to neighborhood fiber nodes, which convert the optical signals to electrical signals and redistributes them on coaxial cables to residents' homes where network interface units send the appropriate signals to the appropriate devices (i.e. television, computer, telelphone).

The cable system is divided into nodes. In most cable systems, there is fiber optic cable running from the cable company to a large box somewhere in that node. Inside that box there is a media converter which converts the signal from optical (light)to RF (radio frequency).

DOCSIS (Data Over Cable Service Interface Specification) is the Cable Modem standard that defines the interface requirements of high-speed data transmission over cable networks. You can also see the CableLabs® Certified logo on some modems, which also means the modem is DOCSIS compliant.

A cable modem is an electronic adapter that permits a personal computer to receive Internet data from the high-speed information resources of a cable television system. Cable modems permit personal computers to receive Internet information at rates of up to hundreds of times faster than typical, consumer market telephone modems. A cable modem attaches to a personal computer through a network interface card (NIC) installed inside the computer. The cable television system's cable brings the information into the cable modem and then the cable modem sends the information into the computer through the NIC.
