Ethernet means a family of computer networking technologies for LANs.
Signaling System 7 (SS7 means a signaling protocol used by the CCS Network.
Common Channel Signaling (CCS means an out-of-band, packet-switched, signaling network used to transport supervision signals, control signals, and data messages. It is a special network, fully separate from the transmission path of the public switched network. Unless otherwise agreed by the Parties, the CCS protocol used by the Parties shall be SS7.
Digital Signal Level 0 (DS-0 means the lowest-level signal in the time division multiplex digital hierarchy, and represents a voice-grade channel operating at either the 56 Kbps or 64 Kbps transmission bit rates. There are twenty-four (24) DS-0 channels in a DS-1.
Network User means each natural or legal person having concluded a Standard Transmission Agreement with the TSO for Transmission Services in the Transmission Grid.
Digital Signal Level 0 or "DS0" means the 64 Kbps zero-level signal in the time-division multiplex hierarchy.
Network Element is As Defined in the Act.
Synchronous Optical Network (SONET means the optical interface standard that allows inter-networking of transmission products from multiple vendors. The base rate is 51.84 Mbps (“OC 1/STS 1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps.
Digital Signal Level 1 (DS-1 means the 1.544 Mbps first level signal in the time division multiplex hierarchy.
Common Channel Signaling (“CCS”) is a method of digitally transmitting call set-up and network control data over a digital signaling network fully separate from the public switched telephone network that carries the actual call.
Terrestrial means to live on or grow from land.
Signaling System 7 (SS7) means a signaling protocol used by the CCS Network.
Digital Signal Level 1 or "DS1" means the 1.544 Mbps first-level signal in the time-division multiplex hierarchy. In the time-division multiplexing hierarchy of the telephone network, DS1 is the initial level of multiplexing.
Digital Signal Level 3 or "DS3" means the 44.736 Mbps third-level in the time-division multiplex hierarchy. In the time-division multiplexing hierarchy of the telephone network, DS3 is defined as the third level of multiplexing.
Bandwidth means a distributor’s defined tolerance used to flag data for further scrutiny at the stage in the VEE process where a current reading is compared to a reading from an equivalent historical billing period. For example, a 30 percent bandwidth means a current reading that is either 30 percent lower or 30 percent higher than the measurement from an equivalent historical billing period will be identified by the VEE process as requiring further scrutiny and verification;
Stack means any point in a source designed to emit solids, liquids, or gases into the air, including a pipe or duct but not including flares.
SPID is the number that identifies a service provider to the relevant NPAC. The SPID may be a state-specific number. "Serving Wire Center" denotes the CenturyLink building from which dial tone for local Exchange Service would normally be provided to a particular End User Customer premises. "Signaling System 7" or "SS7" is an out-of-band signaling protocol consisting of four basic sub- protocols:
SDSL or "Symmetric Digital Subscriber Line" is a baseband DSL transmission technology that permits the bi-directional transmission from up to 160 kbps to 2.048 Mbps on a single pair. "VDSL" or "Very High Speed Digital Subscriber Line" is a baseband DSL transmission technology that permits the transmission of up to 52 Mbps downstream (from the Central Office to the End User Customer) and up to 2.3 Mbps digital signal upstream (from the End User Customer to the Central Office). VDSL can also be 26 Mbps symmetrical, or other combination.
Rack means a mechanism for delivering motor vehicle fuel or diesel from a refinery or terminal into a truck, trailer, railroad car, or other means of non-bulk transfer.
PSTN means the Public Switched Telephone Network.
Spectrum Compatibility means the capability of two (2) copper loop transmission system technologies to coexist in the same cable without service degradation and to operate satisfactorily in the presence of cross talk noise from each other. Spectrum compatibility is defined on a per twisted pair basis for specific well-defined transmission systems. For the purposes of issues regarding Spectrum Compatibility, service degradation means the failure to meet the Bit Error Ratio (BER) and Signal-to-Noise Ratio (SNR) margin requirements defined for the specific transmission system for all Loop lengths, model Loops, or loss values within the requirements for the specific transmission system.
BT Network means the communications network owned or leased by BT and used to provide the Service.
Connectivity means the provision of a Permanent Separated Bicycle Lane system that reflects desired routes between all major origins and destinations in the city.
Digital Signal Level means one of several transmission rates in the time division multiplex hierarchy.
Synchronous Optical Network (SONET) is an optical interface standard that allows inter-networking of transmission products from multiple vendors. The base rate is 51.84 Mbps (“OC-1/STS-1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps.
Core Network means the transport infrastructure identified in accordance with Chapter III of Regulation (EU) No 1315/2013;
