1. Power Outage Post Mortem Outstanding Phone Issues Jeff Custard & Teresa Shibao 2004-01-29

2. Main Issues System Resiliency Information for callers - prevent Security Desk from being inundated Staff Communication

3. Resiliency The best way to mitigate outages is to provide redundancy in the system hardware and the services Incoming Local Long Distance

4. Hardware Redundancy

5. Old PBX Configuration ML is the only path for ALL incoming phone traffic ML is the only path for Long Distance calls

6. Old Configuration

7. New System Configuration Incoming lines are preferred to ML, but if ML not available – calls routed to FL Currently not sized to carry full load May be increased as CG & FL0 are built out Additional Sprint T1 installed at FL Traffic is split by site

8. New Configuration Incoming

9. New Configuration Long Distance

10. Outside Caller Information (303) 497-1000 Only required when entire phone system is down or ML and FL have lost power Are there options for playing a recording during an outage? Incoming Services Vendor can activate a recording after we notify them during an outage $20 per month per routing instance (concurrent call capability) billed regardless of usage Example = 5 concurrent callers - $1200/year Setup within 15 minutes of notification

11. Internal Caller Information Used when particular UCAR service is unavailable (i.e. long distance, local) Shield UCAR Security desk Provide alternative path for UCAR callers and devices We are in the process of testing the capability for adding a recording when service is unavailable. “All lines are currently busy or unavailable. Please try your call later.” Could refer to “Information Line” If this is an Emergency press 1 redirected to security

12. Staff Communications (replaces x1100) Provide Off System Information Line $10 installation $19.95 monthly + usage 300 minutes included 301 – 900 minutes billed at $0.26 per minute 901 + minutes billed at $0.15 per minute Unlimited concurrent callers Local number

13. Staff Communications (continued) Unplanned Outages All Staff Email notification Initial message within 30 minutes after an engineer is notified of major outage Updates every 2 hours until resolution Planned Outages “This Week at UCAR” for outages that will affect a majority of staff NCAB and NNAG aliases for all outages per policy (one week)

14. Priorities & Expectations Increasing System Redundancy System Maintenance Implementing Features Desirable to UCAR Quarterly meetings?
