1. NRIC IVNetwork Reliability and Interoperability Council Washington, DC October 14, 1999 Rick Harrison Telcordia Technologies 732-699-6720 rick6@telcordia.com

2. NRIC IVFocus Group 3 Subcommittee 1 : Observations/Findings Power Continued: Focus on Year 6 7/1/98 - 6/30/99 Outages • 22 Outages • 12 - Root Cause Commercial/Backup Power Failure • 10 Root Cause Procedural • 8 Sub Cause Standby Generator • BPT Findings • 15 Outages with Best Practice implications

3. NRIC IVFocus Group 3 Subcommittee 1 : Observations/Findings Power Continued: Focus on Year 6 7/1/98 - 6/30/99 Outages • BPT Findings Continued • PW69-71 & PR03 All relate to MOPs and Installation Guidelines • PW69 - Telcos should have documented installation guidelines • PW70 - Telcos should clearly communicate their installation guidelines to all involved parties • PW71 - On-site installation acceptance should include a quality review of conformance to the company's and vendor’s guidelines • PR03 - MOPs and Acceptance/Verification Check-off Sheets for Hardware and Software Growth/Change Activities … • All of the above were rated highly effective, implemented and low cost to implement

4. NRIC IVFocus Group 3 Subcommittee 1 : Observations/Findings Power Continued: Focus on Year 6 7/1/98 - 6/30/99 Outages • BPT Findings Continued • Six remaining Outages • 1- Under-engineered for load • 1- Lightning • 4- Engine/hardware failure • 3- multiple failures • 1 - Remote location in the mountains, bad weather forced back helicopter and SnowCat trip was over 4 hours. • Two new Best Practices identified related to Low Voltage Disconnect and Alarm

5. NRIC IVFocus Group 3 Subcommittee 1 : Observations/Findings Continued • Essential Services • ECOMM of NRCII had 33 recommendations which posed many options and alternatives to improve reliability • Many of the above recommendations were complementary and Supplementary • Survey Data indicated confusion regarding implementation responses

6. NRIC IVFocus Group 3 Subcommittee 1 : Observations/Findings Continued • Essential Services • SC1 analysis resulted in a complete revamping of the Essential Services Best Practices • Deleted redundant BPs • Deleted “Not Best” • Combined related options and alternatives that supported the same goals and objectives • ES01 + ES02/ES01 + ES03 = ES04

7. NRIC IVFocus Group 3 ES01 + ES02/ES01 + ES03 = ES04 • ES01- Diverse Interoffice Transport Facilities • ES02 - Diverse Interoffice Transport Facilities with Standby Protection (Option of ES01) • ES03 - Diverse Interoffice Transport Facilities Using DCS (Option of ES01) • ES04 - Fiber Ring Topologies for 911 Circuits (Accomplishes the goals of ES01,02&03)

8. NRIC IVFocus Group 3 • Subcommittee 1 : Observations/Findings Continued • Essential Services • 33 Best Practices Evaluated • 8 Deleted • 7 combined with others • 18 Best Practices

9. NRIC IVFocus Group 3 • Subcommittee 1 : Observations/Findings Continued • Supplier Best Practices • SP05 Human factors represents a new paradigm for vendors. There will be increased “emphasis” due to the Procedural. Errors Team Report. • SP12 Establish Core Team to plan, test and evaluate change - Service Provider initiated BP that suppliers should participate in. Not a Supplier BP Delete (See PR14) • Add PR04 Information Sharing Guidelines - as SP12 • Survey reflects continued high implementation • Confirmed broad industry applicability beyond traditional Telcom suppliers • Combined categories of DCS, Switch and Signaling into 1 Network element category

10. NRIC IVFocus Group 3 Next Steps July -A Best Practice by Best Practice review and analysis of the survey responses COMPLETE -Review NRSC Facilities Solution Team Report for Best Practice implications ONGOING August -Complete survey analysis and gain consensus around final recommendations COMPLETE November -Draft 1 of final report ( deferred due to renewed focus on Power) December -Complete final report
