RedSky also has developed two Legacy Gateway products that provide critical transitional capabilities to 9-1-1 Authorities and PSAPs who are managing the migration toward NG9-1-1 in measured, incremental steps.
RedSky Horizon® Legacy Network Gateway
The first step in properly handling a 9-1-1 call in a NG9-1-1 environment is getting the call in to your private ESInet. The RedSky Horizon® Legacy Network Gateway (LNG) provides the on-ramp for emergency calls from the PSTN from SS7, PRI, CAMA and SIP trunks by translating them into SIP-based signals that can be routed over your secure, private IP networks for handling by the appropriate emergency entity. Intelligence in the LNG then starts the process of building the Location Object (PIDF-LO) associated with the incoming 9-1-1 call.
RedSky Horizon® Legacy PSAP Gateway
Delivering IP-based emergency calls to the vast majority of PSAPs using traditional CPE requires the RedSky Horizon® Legacy PSAP Gateway (LPG). The LPG translates an IP call into traditional CAMA signaling for handling, making it possible for PSAPs to gain the benefits of IP-based networks without upgrading CPE. Just as important, the LPG listens to the CAMA-based PSAP CPE for outbound signaling like hook flash and star code dialing, creating the corresponding SIP instructions and messages.The LPG stores the location data received in the PIDF-LO and formats it as a response to a traditional ALI Query.
