Technical FAQs 4

What are the technical requirements for communication equipment?

This TR report presents the technical requirements for communication equipment with either alternating current (AC) or direct current (DC) as input. At NTT Group, we are implementing DC power supplies because they are advantageous compared to AC ones from the viewpoints of reliability, power-supply efficiency, and economic efficiency.

How does a telecommunications DC power system work?

A simplified diagram of a typical telecommunications DC power system. When power from the grid is lost, the diesel generator is designed to start automatically providing AC power to the DC port system. The ATS synchronizes voltages from different sources to the equipment.

What types of power systems are used in communications infrastructure equipment?

Communications infrastructure equipment employs a variety of power system components. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense, high efficiency DC/DC modules and point-of-load converters on the back-end.

What are the requirements regarding the configuration and operation of communications equipment?

The requirements concerning the configuration and operation of communications equipment are described as follows. Operation of a communications equipment configured with a dual-input system must be unaffected even when a difference occurs between the voltages supplied to both systems.
