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 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 0 or "DS0" means the 64 Kbps zero-level signal in the time-division multiplex hierarchy.
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 1 (DS-1 means the 1.544 Mbps first level signal in the time division multiplex hierarchy.
Digital Signature means authentication of any electronic record by a subscriber by means of an electronic method or procedure in accordance with the provisions of section 3;
Digital Signal Level 3 (DS-3 means the 44.736 Mbps third level signal in the time division multiplex hierarchy.
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.
Wall sign means either a sign applied with paint or similar substance on the surface of a wall or a sign attached essentially parallel to and extending not more than 24 inches from the wall of a building with no copy on the sides or edges.
Antenna means communications equipment that transmits or receives electromagnetic radio frequency signals used in the provision of wireless services.
Signage means advertising displays, hoardings, Glow signs, neon signs, LED signs, LCD signs, any digital signs, any sort of display intended to convey information and described in the schedule.
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.
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.
Network Area means the 50 mile radius around the local school campus the Named Insured is attending.
Brand Name Specification means a specification limited to one or more items by manufacturers’ names or catalogue number.
Modular building manufacturer means a person or corporation who owns or operates a
Install means the complete installation of any item, equipment or material.
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.
Directional sign means a sign that contains only directional information regarding and the identification of 1 of the following:
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.
Automotive windshield washer fluid means any liquid designed for use in a motor vehicle windshield washer system either as an antifreeze or for the purpose of cleaning, washing, or wetting the windshield. Automotive windshield washer fluid does not include fluids placed by the manufacturer in a new vehicle.
Monument sign means a low-profile sign which is incorporated into the landscape or architectural design scheme where the sign is located.
Antenna coating means a coating labeled and formulated exclusively for application to equipment and associated structural appurtenances that are used to receive or transmit electromagnetic signals.
Traffic control signal means a device, whether manually, electrically, or mechanically operated, by which traffic is alternately directed to stop and permitted to proceed.
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.
Satellite means any satellite owned by the Issuer or any of its Restricted Subsidiaries and any satellite purchased by the Issuer or any of its Restricted Subsidiaries pursuant to the terms of a Satellite Purchase Agreement, whether such satellite is in the process of manufacture, has been delivered for launch or is in orbit (whether or not in operational service).
