Overview#
The PSAP NG911 Integration module provides next-generation emergency infrastructure capabilities, enabling Public Safety Answering Points to transition from legacy E911 systems to IP-based NG911 architecture with support for multimedia emergency communications, geospatial routing, and interoperability across jurisdictions.
Key Features#
Core Capabilities#
i3 Standards Compliance Engine#
- Emergency Call Routing Function (ECRF): Determines proper PSAP based on caller location
- GIS-based routing with polygon boundary definitions
- Multi-jurisdictional overlap resolution
- Time-of-day routing for consolidated centers
SIP/RTP Protocol Stack#
- SIP Registration: Trunk registration with carrier partners
- Multiple simultaneous registrations (up to 500 trunks)
- Automatic re-registration with exponential backoff
- TLS transport for encrypted signaling
ESInet Connectivity Management#
- Multi-Carrier Integration: Redundant connectivity
- Primary carrier: Dedicated fiber connection
- Secondary carrier: Alternative fiber path (diverse route)
- Tertiary carrier: Wireless 5G backup for total failure
Legacy System Interoperability#
- Selective Router Integration: Traditional CAMA/MF interfaces
- Multi-Frequency (MF) signaling emulation
- Centralized Automatic Message Accounting (CAMA) trunks
- ALI database query via TCP/IP connection
Emergency Call Data Management#
- Voice Recordings: High-fidelity audio capture
- Recording format: Linear PCM, 16-bit, 8 kHz minimum
- Optional wideband: 16 kHz for improved quality
- Dual-channel recording (caller + call-taker separate)
Performance Benchmarks#
System Performance#
Benefits#
- Improved Location Accuracy: Significant improvement dispatch through 50-meter precision
- Enhanced Caller Information: significant more data enables better decision-making
- Accessibility Compliance: significant improved service for deaf/hard-of-hearing
- Disaster Resilience: Automatic failover prevents service disruption
- Future-Ready: NG911 infrastructure supports emerging technologies
- Multi-Media Support: Text, images, video expand communication options
- Regulatory Compliance: Meet FCC and state NG911 migration mandates
- Public Safety: Faster, more accurate response saves lives
Use Cases#
- Emergency dispatch centers requiring reliable, high-performance operations
- Multi-agency coordination during complex, multi-unit incidents
- Quality assurance and compliance monitoring programs
- Training and skill development for dispatch personnel
- Regional dispatch consolidation and shared services
- Accreditation preparation and ongoing compliance documentation
Integration#
- Multi-Carrier Integration: Redundant connectivity
- Primary carrier: Dedicated fiber connection
- Secondary carrier: Alternative fiber path (diverse route)
- Tertiary carrier: Wireless 5G backup for total failure
- Automatic carrier selection based on quality metrics
- Load balancing across carriers during peak times
- Per-call carrier selection based on caller location
- Carrier performance monitoring with SLA tracking
