31、UT PERMISSION FROM UL 2 General 2.1 Components 2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components used in the products covered by this standard. 2.1.2
32、A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance
33、 with its rating established for the intended conditions of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, a

36、 MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3 Glossary 3.1 For the purpose of this standard the following denitions apply. 3.2 COMMON MODE VOLTAGE When applied to telecommunications leads, this term refers to the voltage between any conductor or conne
37、ction point and earth ground. Also referred to as Longitudinal Voltage. 3.3 DIFFERENTIAL MODE VOLTAGE When applied to telecommunications leads, this term refers to the voltage between any conductors or connection points excluding those connected to earth ground. Also referred to as Metallic Voltage.
38、 3.4 ELECTRICAL ENERGY HIGH-CURRENT LEVELS (POWER SUPPLIES) The capability for damage or injury to persons (other than by electric shock) from available electrical energy is considered to exist when, between a live part and an adjacent dead-metal part or between live parts of different polarity, the
39、re exists a potential of 2 volts or more and either: a) An available continuous power level of 240 volt-amperes or more or b) A reactive energy level of 20 joules or more. For example, a tool (or other metal) short-circuiting a component is capable of posing a risk of re, electric shock, or injury t
40、o persons (burns) when enough energy is available at the component to vaporize, melt, or more than warm the metal. 3.5 ENCLOSURE The word enclosure refers only to parts that house or cover: a) Uninsulated live parts that involve a risk of electric shock or b) Parts that involve a risk of re, electri
41、cal energy/high-current levels, or injury to persons. An enclosure may be an integral part of a component, a separate item or part of an outer cabinet. 3.6 FIXED OR STATIONARY EQUIPMENT Equipment that is not easily moved, and is intended to be moved from one place to another only when de-energized.
42、Fixed equipment is usually fastened or secured to the building. 3.7 GROUND A conducting connection, whether intentional or otherwise, between electrical circuits or electrical equipment and either the earth or some conducting body that serves in place of the earth. 3.8 GROUNDING The act of establish
43、ing a conductive connection, whether intentional or otherwise, between an electrical circuit or electrical equipment and earth. 3.9 LONGITUDINAL VOLTAGE See 3.2, Common Mode Voltage. 3.10 METALLIC VOLTAGE See 3.3, Differential Mode Voltage. 3.11 NETWORK OPERATING VOLTAGES Telecommunications networks
44、 normally operate at voltages of 56.5 volts DC or less, unless the source impedance is above the range of 300 1600 ohms. For equipment connected to a single tip and ring pair, alerting and test voltages higher than 56.5 volts are generally intermittent and will be present over less than 1 percent of
45、 the usage of the MAY 14, 2004 COMMUNICATIONS-CIRCUIT ACCESSORIES - UL 1863 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL equipment. Some telecommunications equipment, such as PBX and Key systems, may have a greater percentage of usage or
46、 operate at a higher voltage (such as T type lines). Maximum ring voltages may not exceed 200 volts peak-to-ground or 300 volts peak-to-peak. 3.12 NONPROTECTED SIDE The portion of the loop circuit that rests on the primary side of a telephone protector installed by the operating telephone company. T
47、he fault current limitation is subject to the breakdown voltage characteristics of the primary protector and its coordinated fusing system (e.g., fuse link or bridle wire) with which the protector is intended to be used. 3.12 revised May 14, 2004 3.13 PORTABLE EQUIPMENT Equipment that is easily move
48、d and can be carried or conveyed by hand. Portable equipment is usually hand-held or hand-supported. 3.14 PRODUCT This term refers to all types of telephone equipment and appliances likely to be used in residential, commercial, and industrial environments. 3.15 PROTECTED SIDE Refers to that portion
49、of the loop circuit that is connected to the secondary or output side of the primary telephone protector and is limited to short and long term current requirements for secondary protectors. 3.16 RISK OF ELECTRIC SHOCK The risk that a person encounters when exposed to live uninsulated parts of a product that have a voltage and current sufficient to cause an electric shock, as dened in Accessibility and Electric Shock, Section 8. 3.17 RISK OF FIRE The risk that a re may occur a
