New IEEE Standard - Superseded. Prescribes criteria that establish protection requirements for Class 1E power systems and equipment. It describes the purpose of and the means for obtaining protection from electrical and mechanical damage, or failures that can occur within a time period that is shorter than that required for operator action. It includes both design and documentation requirements. It does not include physical plant design requirements to protect against certain events. .
The purpose of this standard is to establish functional requirements for measuring analog transmission characteristics of voice frequency telecommunication equipment including voiceband and wideband data transmission channels and program circuits, and to establish functional requirements for test equipment needed to make the required measurements. Section 2 of this standard contains definitions. Section 3 presents a general, somewhat tutorial review of the measurements, while Section 4 presents the details of the standard for each measurement. Section 5 addresses physical characteristics and Section 6 environment. This standard will be useful for specifying test equipment for measuring the performance of subscriber loops, message network trunks, PBX trunks, tie lines, and other similar facilities.
