Traffic control signal means a device, whether manually, electrically, or mechanically operated, by which traffic is alternately directed to stop and permitted to proceed.
aerodrome control service means air traffic control service for aerodrome traffic;
Digital Signal Level means one of several transmission rates in the time-division multiplex hierarchy.
Digital Signal Level 3 or "DS3" means the 44.736 Mbps third-level signal 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.
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. There are twenty-eight (28) DS1s in a DS3.
Control system means the combination of capture and control devices used to reduce emissions to the atmosphere.
air traffic control service means a service provided for the purpose of:
Digital Signal Level 1 (DS-1 means the 1.544 Mbps first level signal in the time division multiplex hierarchy.
Digital Signal Level 3 (DS-3 means the 44.736 Mbps third level signal in the time division multiplex hierarchy.
Digital Signal Level 0 or "DS0" means the 64 Kbps zero-level signal in the time-division multiplex hierarchy.
approach control service means air traffic control service for arriving or departing controlled flights;
Control apparatus means any device which prevents or controls the emission of any air contaminant directly or indirectly into the outdoor atmosphere.
Control device means equipment (such as an incinerator or carbon adsorber) used to reduce, by destruction or removal, the amount of air contaminants in an air stream prior to discharge to the ambient air.
area control service means air traffic control service for controlled flights in control areas;
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.
Control Area(s) means an electric power system or combination of electric power systems to which a common automatic generation control scheme is applied.
Railroad sign or signal means any sign, signal, or device erected by authority of a public body or official or by a railroad and intended to give notice of the presence of railroad tracks or the approach of a railroad train.
Emission Control Strategy means any device, system, or strategy employed with a diesel-fueled CI engine that is intended to reduce emissions. Examples of emission control strategies include, but are not limited to, particulate filters, diesel oxidation catalysts, selective catalytic reduction systems, alternative fuels, fuel additives used in combination with particulate filters, alternative diesel fuels, and combinations of the above.
Control Centre means the central facility of the Cycle Sharing System used mainly for service monitoring, operations control, and customer service. It is the location for collecting, storing, consolidating, processing the information obtained from various elements of the Cycle Sharing System as well as from users, agents, employees, and service providers.
Control Area means an electric power system or combination of electric power systems bounded by interconnection metering and telemetry to which a common automatic generation control scheme is applied in order to:
control zone shall have the meaning given in the Operating Agreement.
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.
Safety Management System means a systematic approach to managing safety, including the necessary organizational structures, accountabilities, policies and procedures;
Biological safety cabinet means a containment unit suitable for the preparation of low to moderate risk agents where there is a need for protection of the product, personnel, and environment, according to National Sanitation Foundation (NSF) Standard 49.
Quality control means the total of all activities performed by the Design-Builder, Designer, Construction Inspection Professional Engineering Firm and the Materials Testing Firm or Laboratory, subcontractors, producers or manufacturers to ensure that the Work performed by the Design-Builder conforms to the Contract requirements. For design, Quality Control activities shall include, but not be limited to, procedures for design quality, checking, design review including reviews for constructability, and review and approval of Working Plans. For construction, Quality Control activities shall include, but not be limited to, procedures for materials handling and construction quality, inspection, sampling and testing of materials both on site and at the plant(s), field testing of materials, obtaining and verifying Materials Certifications, record keeping, and equipment monitoring and calibration, production process control, and monitoring of environmental compliance. Quality Control also includes documentation of all QC design and construction efforts. The Scope of Work to be performed as part of the Quality Control task may be changed after the RFQ Phase.
Control equipment means equipment necessary for the setting and/or unsetting of an immobilizer.
