Diameter at breast height (dbh) means the diameter of a tree at 4 1/2 feet above the ground measured from the uphill side.
Digital Signal Level 1 (DS-1 means the 1.544 Mbps first level signal in the time division multiplex hierarchy.

High voltage bus means the electrical circuit, including the coupling system for charging the REESS that operates on a high voltage.
Mean Sea Level means the average height of the sea for all stages of the tide. It is used as a reference for establishing various elevations within the floodplain. For the purposes of this Ordinance, the term is synonymous with the National Geodetic Vertical Datum (NGVD) of 1929, the North American Vertical Datum (NAVD) of 1988, or other datum, to which Base Flood Elevations shown on a community's Flood Insurance Rate Map are referenced.
Integrated Digital Loop Carrier means a subscriber loop carrier system that is twenty-four (24) local Loop transmission paths combined into a 1.544 Mbps digital signal which integrates within the switch at a DS1 level.
high voltage means the classification of an electric component or circuit, if its working voltage is > 60 V and ≤ 1500 V DC or > 30 V and ≤ 1000 V AC root mean square (rms).

Broadband level means all positions sufficiently similar in knowledge, skills, and abilities, and sufficiently similar as to kind or subject matter of work, level of difficulty or responsibilities, and qualification requirements of the work, to warrant the same treatment as to title, pay band, and other personnel transactions.
Strike Level means the Strike Level as specified in § 1 of the Product and Underlying Data.
Flash point means the lowest temperature of a liquid at which its vapours form a flammable mixture with air;
Rated Voltage means the manufacturer’s design voltage at which the transmission system is designed to operate or such lower voltage at which the line is charged, for the time being, in consultation with Transmission System Users;
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;
