Executive Summary
The Adaptive Systems Interface Specification (APSIS™) is a method by which cable broadband providers can address and control energy management from an end to end perspective. The 2020 release contains updated references, reorganizes some content, and recognizes YANG data modeling as another device level protocol opportunity. The general idea behind APSIS is that power consumption should be reflective of demand.
Scope
This document is part of the work being done in SCTE’s Standards Energy Management Subcommittee (EMS). The Adaptive Power System Interface Specification (APSIS) working group under the EMS is responsible for the creation and updates of this document. The document was developed for the benefit of the cable industry and includes contributions by cable operators, vendors and industry support organizations. While the initial intent of this document is to support the cable industry, the process, methodology and results of this effort may be applicable to other telecommunications networks.
The focus of this specification is to define interfaces within the domain of cable service delivery networks, including the cable ‘plant’, data centers, digital voice platforms, wireless platforms, and other communications and distribution electronics.
The intent of this document is to identify the appropriate energy related data necessary to measure and manage energy consumption and define protocols used for the data exchange. This specification is intended to enhance business continuity and disaster recovery by optimizing the performance, availability, and reliability of cable networks, optimize expenditure on energy, and improve the Mean Time Between Failures (MTBF) and extend the useful life of components and equipment.
Benefits
Cable network operators continue to add customers to their broadband telecommunications networks and provide more services and data over those networks. These factors increase demand for power, and forecasts for utility power availability and cost show that energy management will become an important element in cost-effectively delivering services. Service provider goals addressed by energy management include higher customer satisfaction, more cost-efficient operations, lower energy costs, and rapid product deployment.

Intended Audience
Cable broadband provider network engineers, power managers, cable provider network equipment manufactures and procurement mangers.
