The Statewide 911 Board, in partnership with the Indiana Department of Administration, initiated a Request for Service procurement (RFS15-12) in the summer of 2014. The request for service (RFS) document that was published for the procurement required a vendor(s) to build out an Internet protocol NG9-1-1 network for part or all of Indiana to provide an equal level of service to all PSAPs. The RFS required the vendor(s) to meet or exceed the level of service offered today by the IN911 network.
In December 2014, the board awarded bids to three vendors as part of the RFS15-12. Those vendors included INdigital telecom and AT&T for network call delivery services for wireless 9-1-1 traffic and a third contract was awarded to ECATS for a statewide comprehensive data analytics system. Implementation started in the summer of 2015 and estimates that it will take 18 to 24 months to have AT&T's secondary network completed and all PSAPs transitioned to the ESInet. This project will result in all PSAPs operating in a NG9-1-1 environment.
The Indiana Statewide 911 Board provides a single, statewide private E9-1-1 network (IN911 network) to handle 911 calls from cellular phones.
A self-healing Synchronous Optical Network (SONET) serves as the transport network for a diverse IP-based ‘mesh network’ that delivers 9-1-1 voice and ALI data using IP technology. Internet Protocol signaling is converted to analog voice and traditional RS-232 data communications to serve legacy equipment in the back room of the local PSAP. The IN911 network is fully redundant at all levels, with redundant, paired selective router tandems and multiple IP-based selective routing services, redundant ALI links and controllers. The underlying IP transport is fully redundant to each PSAP, and the connections to all legacy LEC network elements used for 9-1-1 service are redundant as well. In addition, tertiary connections are being added at critical network points where the unreliability of legacy circuits has been observed. The IN911 network is a fully private network that makes extensive use of IP security protocols and procedures.
In addition to the redundant nature of the IN911 network design, the Board has implemented tertiary connections from third party service providers. Tertiary connections are added to the 9-1-1 network as high speed broadband networks are established in the PSAP’s communities. These connections, where available, are used to connect multiple providers’ networks for improved delivery of wireless 9-1-1 calls.
The network is evolving to support additional agencies to promote public safety for Indiana residents and visitors. The Board has extended the IN911 network across state boundaries into Michigan, Ohio and Kentucky to enable wireless call transference across state lines along with the location information associated with the call; interconnectivity with Illinois is in progress.
