IEEE-487 Standard for the Electrical Protection of Communications Facilities Serving Electric Supply Locations — General Considerations
Chair: John Fuller Vice-Chair:
Scope: General considerations are presented for the electrical protection of telecommunications facilities serving electric supply locations. This standard contains material that is common to the IEEE 487(TM) family of standards (i.e., dot-series) including fundamental protection theory; basic electrical protection philosophy, concepts, and designs; protection apparatus; service types; reliability; service performance objective (SPO) classifications; and transmission considerations. In general, special protective measures, handling procedures, and administrative procedures are necessary to provide electrical protection against damage to telecommunications facilities and equipment, maintain reliability of service, and ensure the safety of personnel.

IEEE-776 Recommended Practice for Inductive Coordination of Electric Supply and Communication Lines
Chair: John Fuller Vice-Chair:
Scope: This recommended practice addresses the inductive environment that exists in the vicinity of electric power and wire-line telecommunications systems and the interfering effect that may be produced thereby; guidance is offered for the control or modification of the environment and the susceptibility of the affected systems in order to maintain an acceptable level of interference. An acceptable level is defined as an amount of steady-state or surge induced longitudinal voltage or current that does not cause a personnel or public safety hazard, damage to cable or equipment, and/or circuit degradation or failure. To aid the user of this recommended practice in calculating induction between power and telecommunication lines, the concept of an interface is developed. This recommended practice permits either party, without need to involve the other, to verify the induction at the interface by use of a probe wire. This recommended practice does not apply to railway signal circuits.

IEEE-789 Standard Performance Requirements for Communications and Control Cables for Application in High-Voltage Environments
Chair: Percy Pool Vice-Chair:
Scope: This standard applies to wires and cables, used principally for power system communications and control purposes, which are located within electric supply locations or are installed within the zone of influence (ZOI) of the power station ground potential rise (GPR), or which may be buried adjacent to electric power transmission and distribution lines. This standard covers the appropriate design requirements, electrical and mechanical parameters, the testing requirements, and the handling procedures for cables that are to be installed and operated in high voltage environments where they may be subjected to high voltages either by conduction, or induction coupling, or both. Coaxial and fiber optic cables, except for those used in Ethernet applications, are specifically excluded from this standard.
Status: Inactive-reserved
IEEE-820 Standard Telephone Loop Performance Characteristics
Chair: John Fuller Vice-Chair:
Scope: This standard covers the general parameters and characteristics associated with telephone loops from the subscriber signaling and analog voice frequency interface to the local Class 5 switch interface. It includes only those business and residential lines in the North American public switched network where no special performance requirements are involved. This standard provides common denominators for subscriber line performance, independent of facility types, construction processes or equipment, and circuit provisioning methods.
