3.1.3 AC Power port Flicker: Short-term and long-term voltage changes at the interface between theequipment under test and the electric supply system, produced by the equipment under test.
3.1.4 AC Power port Harmonics: Harmonic components of the input current injected into the electricsupply system, produced by the equipment under test.
3.1.5 Access Broadband over Power Line (BPL) equipment: Devices that enable Access BPL andtogether comprise an Access BPL system: BPL Bridges, Backhaul-Interfaces, Couplers, BPL RepeatersBPL equipment does not include accessories: e.g, connecting cables attached to BPL equipment but notessential for the provision of BPL.
3.1.6 Back-filter: The decoupling section of a coupler-decoupler network (CDN) designed to preventinterference from effecting auxiliary equipment during an immunity test.
3.1.7 Backhaul-Interface: The primary data interconnect point that connects the BPL system to theTelecommunications Network Point of Presence; aggregating and managing the data traffic to/from itsdownstream BPL Bridges.
3.1.8 Broadhand over Power Line (BPL): A carrier current system carrying high speed digitalcommunication on frequencies between 1.7 MHz and 100 MHz over medium voltage and/or low voltagepowerlines.Also know as Powerline Communication (PLC)
3.1.9 BPL Bridge: A device that provides a data interconnect between two or more segments of the powergrid providing data interconnection from one medium to another.
3.1.10 BPL equipment: Devices that enable BPL, including Access BPL and In-Premises BPL
3.1.11 BPL repeater: A device which retransmits the signal on the power line without changing protocol.
3.1.12 Capacitive Coupler: A device that couples data signals bi-directionally onto a power line, andincludes a capacitive element connected to the power line
3.1.13 Coupling/decoupling network (CDN): a device for introducing a disturbance at ports that are tobe tested and having provisions for isolating disturbances from the auxiliary equipment.
3.1.14 Coupler Port: The terminal(s) on the BPL communications device that connect to the coupler.
3.1.15 Demarcation Point: The point of changeover from Access to In-premises BPL.
3.1.16 Distance correction factor: A scaling factor that enables a radiated emissions measurement madeat a distance different from the reference distance at which emissions limits are specified to be extrapolatedto the value that would be present at the reference distance.
3.1.17 Electrical fast transients (EFT): A conducted transient disturbance created by switching powercurrents via electrical contacts.
3.1.18 Electrostatic discharge (ESD): A transfer of electric charge between bodies of differentelectrostatic potential in proximity or through direct contact
3.1.19 Immunity: Ability of a device, equipment or system to perform without degradation ofperformance in the presence of electromagnetic disturbance
3.1.20 Inductive Coupler: A device intended to couple data signals bi-directionally onto a power line, andincluding an inductive element electrically in series with the power line.
3.1.21 In-Premises Broadband over Power Line (BPL) equipment: Equipment required in a CarrierCurrent System providing high speed digital communications capabilities by coupling RF signals onto thepower lines (those not owned or operated by an electric service provider) within a premise
NOTE-Access BPL systems may physically have components within the premises. The separation ofAccess BPL and In-Premises BPL is not necessarily the physical boundary of the building.
