1. Together, we’re changing the world of 9-1-1 NG9-1-1 Deployments and Standards Nate Wilcox CTO

2. Together, we’re changing the world of 9-1-1 Basics NG9-1-1 Requirements – basics: – ESInet – i3 functions ESRP, ECRF/LVF, BCF and accompanying protocols Mostly only ESInet’s (1 st step to i3) – Privately managed IP network intended for Emergency Services use (9-1-1 traffic etc.) to support NENA i3 functions “some” i3 components required Confusion on routing component

3. Together, we’re changing the world of 9-1-1 Not NG9-1-1 Non-i3 oriented solutions: – No ESRP, no ECRF, no LSRG etc Running an ESInet alone or on an ESnet is NOT NG9-1-1 Anything that still relies on ALI or an MSAG To date, there are NO complete i3 implementations in the US – Less than a year for the first few to hit

6. Together, we’re changing the world of 9-1-1 Implementation Challenges Voice Quality – Echo – Echo produced by the analog “hybrid” in almost ALL cases (2 to 4 wire conversion – w/an impedance mismatch). – Delays either in the ESInet or the PSTN side > 120 ms Multiple aspects can introduce delay – Transmission:100 miles = 1 msec – Gateways can introduce 50 msec – Etc – Fix – echo cancellation Well placed using G.168

7. Together, we’re changing the world of 9-1-1 Implementation Challenges Network specifics – Service SLA’s Typically little more than 2-9’s Network downtime results in a MRC discount Restrictions on network hosts (MAC specific) – Fix – Consider multiple network vendors Create SLA’s for them to consider Read and understand existing network contracts Determine acceptable failures as they relate to overall 5- 9’s
