ANSI SCTE 238:2017 pdf download.Operational Practice for Measuring and Baselining Power Consumption in Outside Plant Equipment and Power Supplies.
ANSI/SCTE 211 2015 [3] describes energy metrics for access networks, and ANSI/SCTE 212 2015 [2] describes an overall framework for performing energy audits and establishing baseline energy consumption in cable access networks. however, even with the ANSIISCTE 212 2015 [2] framework, portions of cable networks do not easily lend themselves to exact measurement and monitoring of energy consumption due to the lack throughout the network of certified utility metering andlor modern monitoring solutions built into the power supplies. This document thus provides specific operational practices in support of the ANSI/SCTE 212 2015 [21 standard fbr defining how cable operators can audit power consumption and accurately establish an energy baseline in access networks as they currently exist. This document is limited to the outside plant equipment and excludes any customer powered equipment. Inside plant, i.e. equipment located in critical facilities at the network edge, should be covered in a separate operational practice document.
1.3. Benefits
The immediate and long term benefits include:
• Developing an accurate model of actual energy consumption in the OSP for current and evolving network architectures
• Identifying near term opportunities for plant improvements or upgrades that can lead to substantial improvements in OSP energy efficiency
• Identifying opportunities for static/dynamic energy monitoring and management in the OSP
This document supports the Energy 2020 roadmap for improving energy efficiency in cable networks, especially in the access network where the majority of energy consumption occurs.
This document can be customized for your workforce/cable network specifics. Implement the practices, keeping track of key performance indicators (KPIs) both before and after the implementation to ensure it is meeting the business goals of the cable operator.
1.4. Intended Audience
The intended audience includes engineering and operations staff involved in planning to improve energy efficiency, outside plant technicians, field and installation technicians, training content developers, and those with an interest in energy consumption in outside plant equipment.
1.5. Areas for Further Investigation or to be Added in Future Versions
The EMS-A NE working group is currently developing a reference model for a separate document (EMS033) and plans to include for example procedures for developing detailed models and examples of typical OSP architectures, lab testing/characterization of individual components as they are submitted for repair, and building a table of product by age to cross reference against a cable operator’s network map, as well as other methods to accomplish the reference model with lab measurements method.
Also, further deas and suggestions for future investigation and development are presented throughout this document. See the final paragraphs in sections 6.3 and 6.4 for specific ideas.
