MPTL to be specified within AS/NZS 11801-1 MPTL Testing Channel testing is not appropriate as it does not test the plug on the end of the cable High dependency links Poor connector choice means high chance of failure Poor termination means high chance of failure Least tested links installed 5 October 2018 www.vti.net.au 16

Remote Power over Twisted Pair 90-100 watts of delivery DC unbalance may affect the operation of a device DC unbalance testing may be called up as an additional field test Recommended infield tests to do for cabling supporting PoE Direct current (DC) resistance unbalance within a pair Direct current (DC) resistance unbalance between pairs Recommended infield tests DO NOT SPECIFY COUPLING ATTENUATION 5 October 2018 www.vti.net.au 19

One Pair cabling Generic cabling links in support of one pair cabling Long reach Not intended to replace four pair 1000 metre reach PAM 3 signalling Power delivery Industrial 15 metre reach Indications from the IEEE802.3 liaison was that the IEEE 802.3bt draft had included a warning against using smaller than 26AWG cabling (90m). However, now the text indicates compliance with local, national and regional codes is required. Including NFPA70 in US (NEC) AS/CA S009 is likely to recommend 24 AWG as a minimum for twisted pair cabling 5 October 2018 www.vti.net.au 22
Remote powering over one pair Work started on heat rise in one pair cabling in Paris February 2018 Australian expert requested heat rise in multicore cables be taken into account Heat rise in multi-core cables would be useful to address the impact on safety in AS/CA S009 ISO/IEC TS 29125 provide some useful methods of calculation 5 October 2018 www.vti.net.au 23
Security of cabling (Physical Network Security) Work started on addressing Issues related to the physical security of cabling and network infrastructure at the Washington meeting of SC25 WG3 in September 2018 The proposed standard objectives are to address Conformance requirements (Tiered) Risk assessment and security objectives Design Planning Monitoring system

New Standards Dependency on technology and supporting infrastructure IoT Convergence Power Delivery of Telecommunications Cabling Lack of understanding of risk What Changed Lack of expertise within emerging technology 5 October 2018 www.vti.net.au 27
Risk Mitigation Strategy Risk Mitigation relates to a strategy to reduce exposure to risks or the likelihood of its occurrence based on four primary elements Risk Acceptance Risk Avoidance Risk Limitation Risk Transfer 5 October 2018 www.vti.net.au 28
Are you confident your strategy will address? The validity of your specification Information/Knowledge Dissimulation of your staff Test and acceptance criteria to mitigate risk Address Risks associated with engineered solutions Issues with remote powering The impact of product selection When standards don t guarantee safety 5 October 2018 www.vti.net.au 29
Recommendations Engage with, attend training and seek advice from Industry organisations like BICSI Trusted advisors within your cable system vendors organisations Develop risk mitigation strategies Refresh your organisation specification and identify risk and communicate Develop staff knowledge Have preferred suppliers and contractors with suitable knowledge and understanding of the changes 5 October 2018 www.vti.net.au 30
What the future holds Personal predictions for the next big things 1. Remote power - Now 2. One pair cabling Next 1 to 3 years 3. Security of Physical infrastructure Next 3 to 5 years
