Selective Routing at your fingertips

The Next Generation 9-1-1 Challenge

Until recently selective routing to the PSAP relied on tabular-based routing. Today, with the increase in mobile devices and IP-based communication, your emergency services need to route VoIP, IM, and other IP communications, in addition to TDM calls. You need a Next Generation Selective Router that can:

• Exceed NENA’s i3 standards for Next Generation call routing
• Bridge the gap between legacy infrastructure (PSTN) and emerging IP technologies
• Deliver IP media directly to your PSAP from any source
• Route based on spatial data in addition to tabular data
• Provide a non-proprietary, software-based device that can evolve with technology
• Easily integrate with your existing infrastructure and services on the Emergency Services IP Network
• Offer a highly available, fault tolerant system
• Communicate with i3 services (LoST, ECRF and LVF)
• Eliminate the CPE! Deliver calls directly from the ESInet direct to call taker positions
• Save money by building a shared ESInet with other agencies
  

Our Solution

xSR™ (an IP-based Selective Router) operates as a replacement for legacy selective routers with an
NG9-1-1, IP-based solution. Where circuit-switched selective routers relay calls according to routing tables, xSR™ relays calls based on geospatial data. When receiving a Presence Information Data Format Location Object (PIDF-LO) and querying the GIS database, xSR™ assures that all call types are relayed to the correct PSAP. Nomadic callers using cellular or VoIP are correctly relayed, ensuring accuracy and rapid response.
xSR™ converts all TDM calls into SIP, the protocol specified by NENA for i3 call routing. This provides for seamless relay over the Emergency Services IP Network (ESInet). xSR™ bridges the gap between legacy
9-1-1 systems and Next Generation 9-1-1 and enables the processing of landline calls, wireless and IP-based communications, including VoIP.

xSR™ meets your challenges:

• No single point of failure
• Queries both spatial and tabular data
• Operates in conjunction with legacy infrastructure (TDM) and IP-based networks
• Is built on COTS equipment with a future-proof software based solution
• Integrates with existing TDM infrastructure and other ESInets
• Offers full i3 compatibility including LoST queries
• Is deployed on load-balanced and fault tolerant servers
• Moves your Selective Router into your PSAP today
