Indiana Enhanced 911

911 Coverage > Public Safety ESInet Public Safety ESInet


The state of Indiana provides a statewide Emergency Service Internetwork (ESInet) known as the IN911 network.  This network processes 9-1-1 calls throughout the state.  The IN911 network is the first large scale ESInet, and one of the largest in existence.  It uses a self-healing Internet Protocol over Synchronous Optical Network (SONET) fiber connections that deliver 9-1-1 voice and supplemental call data.

As of 2012, there are 21 Indiana counties using call taking equipment that is NG9-1-1 compliant, and they are directly connected to the IN911 network.  To ensure compatability, IP signaling is converted to analog connections for voice and data to provide legacy support for all other local authorities.

All elements that make up the IN911 network are 100 percent redundant.  Additionally, transport service is provided by a number of different network operators to ensure high availability of the IN911 network, and many leading edge implementations of the FCC's best practices for public safety are in place.

The network is evolving rapidly within the Midwest region, and additional agencies in the surrounding states are also connected to the IN911 network.  This prompts improved public safety for Indiana residents and visitors.

The Indiana 9-1-1 board is finalizing the extension of the IN911 network across state boundaries into Michigan, Illinois, Ohio and Kentucky.  This will enable wireless 9-1-1 calls to be transferred across state lines and keep the caller's location information associated with the call.

Indiana has a competitive 9-1-1 marketplace for goods and services, and the state's 9-1-1 system service providers have all made significant improvements in their product lines and the level of service they provide.



INdigital Telecom of Fort Wayne, Indiana serves as the network provider for all Wireless E91-1-1 calls, operating the IN911 network.  For more information about the state's   NG91-1-1 network, please visit  (Additional information about INdigital is located at
