ANSI SCTE 237-2017 pdf free download.Implementation Steps for Adaptive Power Systems Interface Specification (APSIS™)
1. Introduction
1.1. Executive Summary
The intent of this document is to outline the high-level implementation steps necessary for cable operators to enable/implement ANSI SCTE 216 2015: Adaptive Power Systems Interface Specification (APSIS™ ).
1.2. Scope
SCTE 216 addresses the end to end network; therefore, an implementation of APSIS can touch back
office networks, backbone networks, transport networks, access networks and customer premise
equipment. The primary focus of APSIS has been the access network including critical facilities and
outside plant.
1.3. Benefits
Implementation Steps for Adaptive Power Systems Interface Specification (APSIS) provides the high-level overview to help identify essential steps necessary and a logical order of approaching the necessary steps to enable end-to-end energy control.
1.4. Intended Audience
This document is intended to be referenced by network architects, engineers and implementers at cable operator organizations.
1.5. Areas for Further Investigation or to be Added in Future Versions
Definitive use cases that would apply when a condition would warrant APSIS to ramp up or down the
power being consumed.

The application domain encodes logic to collect and process energy measures and issue energy controls. The application layer may be composed of many independent processes executing simultaneously, and may include heavyweight ‘big data’ applications and lightweight alarm processors, and many other functions. Applications may input other data sources such as measures of service level in order to perform its tasks. The application domain may include a middleware layer to offer basic device discovery and connectivity services on behalf of all applications, greatly reducing the complexity for each energy specific application. One such middleware is the open-source OpenDaylight Software Defined Networking controller with the EMAN (Energy Management) plug-in. Annex A includes a diagram of a layered software model.
6.1.1. Step one: Inventory
Inventory of devices that are able to: one) – report energy conditions via software interfaces, and two) – be controlled via these software interfaces for the amount of energy consumed in the process of enabling APSIS™ on the network. Without a solid understanding and inventory of current network-to-power awareness, unnecessary programming or missed opportunities could occur. Because few devices support APSIS™ today, this process is not programmatically supported by the APSIS™ platform and step one must be performed in an operator defined way.
6.1.2. Step two: Measurement
Energy measurement is step two in the process of enabling APSIS™ on the network. Collecting a good understanding of how much power the end-to-end network consumes should help the cable operator prioritize where to target the rollout of APSIS™ based on greatest opportunity. While APSIS™ supports detailed, programmatic energy measurement, step two must be performed in an operator defined way.
