Backbone connection point: Historically defined as a NAP (Network Access Point). Typically, it depicts a "node" on a carrier backbone that is used to provide access to a region, network of users or another carrier. It can also be used to define a location (physical data center/carrier hotel) where multiple providers converge to "peer" or provide "transit" to other providers. Peering is a method of traffic exchange which occurs at no cost to either provider because it is mutually beneficial to do so. Transit refers to providing access/bandwidth from one carrier to another for a fee.
Backhaul: A "link" or portion of a network that carries traffic from the aggregation nodes of a network to the core network. DSL Example ---- DSL Subscriber ----> DSLAM ----> Central Office (CO). The portion of the network that connects the DSLAM, a type of aggregation node, to the CO is referred to as backhaul. Backhaul bandwidth may range from smaller than a T-1 to OC-N capacities. (less than 1.54Mbps to nearly 10Gbps) A relevant example is the role of the Middle Mile carrier. They provide backhaul connectivity between geographically separated networks that are owned/managed by the same company. Example - Level 3 provides backhaul to Cox Communications that connects their Phoenix and Tucson markets.
Basic Cable: Primary level or levels of cable service offered for subscription. Basic cable offerings may include retransmitted broadcast signals as well as local and access programming.
In addition, regional and national cable network programming may be provided. Basic service offerings at the system level may be offered as more than one tier.
Bipolar Signal: A signal that can take on two polarities, of which neither is zero.
Box: Electronic equipment used to process television signals in a consumer’s home, usually housed in a “box” that sits atop a TV set or VCR. See also CONVERTER and DESCRAMBLER.
(BPS) Bits Per Second: Transmission rate for digital information expressed as the number of bits (zeroes or ones) sent or received per second.
Broadband Communications System: A network such as a cable system capable of delivering multiple high capacity services simultaneously.
(BS) Base Station: A fixed land station in the land mobile service that relays signals to and from mobile voice and data terminals or handsets.
(BSS) Business Support System: A system that supports and manages information of various telecommunication functions such as billing, data warehousing, customer care, network management and account receivables.
Businesses passed: As in "homes passed", typically a term used by Cable Operators, is the actual number or percentage of commercial structures that can be connected to "nearby" cable plant inexpensively. Penetration rates are often used against homes/business passed for a specific geographic area, market or even zip code.
(BW) Bandwidth: A measure of the capacity of a channel of communications in the broadcast spectrum. A range of frequencies or the amount of spectrum used to transmit pictures, sound, and data (In the United States, the Federal Communications Commission has assigned broadcast television channels a bandwidth of 6 megahertz).
Bundling: Combining goods and/or services into a single package, often for a discounted price.
