1. Network Reliability and Interoperability Council VII NRIC Council Meeting Focus Group 1C Analysis of Effectiveness of Best Practices Aimed at E911 and Public Safety September 23, 2004

2. Network Reliability and Interoperability Council VII 1 Focus Group 1C Charter “The Council shall present a report containing its analysis of 63.100 outages related to 911/E911 and the Best Practices that are most applicable to E911 outages. The report shall also identify E911 architecture vulnerabilities.”

4. Network Reliability and Interoperability Council VII 3 Outages Reviewed & Qualified C.F.R. § 63.100 Reported Outages affecting 911 between January 2002 and March 2004 –FCC data: 84 outages –NRSC summary: 80 outages –Focus Group 1C review: 76 outages Eliminated reported outages that: –Did not affect 911 –Were finally determined to not meet 63.100 reporting criteria

5. Network Reliability and Interoperability Council VII 4 Definitions: Root Cause and Direct Cause The Direct Cause is defined as the event, action, or procedure that triggered the incident e.g., “Cable damaged by falling tree”* -Direct Cause – Cable Damage The Root Cause is defined as the key problem, which once identified and corrected prevents the same or a similar problem from recurring e.g., “…switch was improperly configured to allow auto reroute of calls”* -Root Cause – Service Provider Procedural Error * - from Outage 02-016

6. Network Reliability and Interoperability Council VII 5 Results in Brief – Outages by Direct Cause

7. Network Reliability and Interoperability Council VII 6 Results in Brief – Outages by Root Cause

8. Network Reliability and Interoperability Council VII 7 Results in Brief – Outage Categories

9. Network Reliability and Interoperability Council VII 8 Results in Brief – Facility Failure

10. Network Reliability and Interoperability Council VII 9 Results in Brief – 911/E911 Best Practices 97 out of the 776 existing NRIC Best Practices from NRIC I-VI were identified as being applicable specifically to 911/E911 outages and Public Safety The Best Practices identified fell into the following categories: –Diversity/Redundancy –Contingency/Emergency Planning –Data Assurance/Traffic Management –Media/Public Awareness –Emergency Management –Prevention –Cooperation/Communications with Emergency Service Entities Future 1C efforts will evaluate the effectiveness of 911/E911 and Public Safety Best Practices

11. Network Reliability and Interoperability Council VII 10 Results in Brief – 911/E911 Architecture Vulnerabilities Five areas of the 911/E911 architecture were identified as key vulnerabilities when analyzed against the outage data –Facility Affected by 47% of the 911 outages –Power Elements Affected by 16% of the 911 outages –CCS (Common Channel Signaling) Affected by 15% of the 911 outages –Local Switch & Tandem Switch Affected by 9% and 4%, respectively for a total 13 % of the 911 outages –DCS (Digital Cross-Connect System) Affected by 7% of the 911 outages
