Sentinel
IP Radio Gateway

Analog-to-IP Conversion for Seamless, Secure, and Scalable Radio Connectivity.
The Sentinel IP Radio Gateway represents the next generation of analog-to-IP conversion solutions. Optimized for operation at remote sites with IP connectivity, Sentinel can handle wireline and microwave bearer circuits, including the ability to mix different types of circuits. The Sentinel interfaces 2/4/6 wire radios to your IP network for audio communication. Designed for public safety, utilities, transportation, and critical infrastructure, Sentinel enables secure, reliable, and scalable radio connectivity.

Key Features
Analog-to-IP Conversion – Effortlessly connect 2/4/6-wire radios to your IP network for seamless communication.
Compact & Scalable – Small form factor with support for multiple base stations, peer-to-peer receiver voting, and unit identification.
Secure & Resilient – Embedded Linux OS, TLS encryption, and FIPS 140-2 compliant security measures.
Multi-Protocol Support – Works with analog, P25 and other digital radio systems.
Flexible Connectivity – Supports Tone Remote Control (TRC), MDC-1200, E&M Signaling, and more.
Advanced Donor Radio Features
The Sentinel IP Radio Gateway is capable of providing advanced digital radio features with Tait, Kenwood, L3 Harris and MotoTRBO digital radios. These features include:
Channel/Frequency Change – Allows a dispatcher to change the channels or frequencies of the connected device. The interface supports up to 16 channels or frequencies, depending on the characteristics of the radio system.
PTT ID / Alias – Gives a dispatcher a visual indication of the identity associated with the last voice transmission. An identity can represent the raw subscriber unit ID (PTT-ID) or an alphanumeric string representation of it (ANI Alias). The identity can display in the Activity History and on the associated endpoint pad using the ANI pad extender. For example, a PTT ID of 2225 can be aliased to “Police 1.”
Emergency Calls/State – Notifies a dispatcher of an emergency situation in the field using a unique ring and visual indication. When a subscriber presses the emergency button or dials the emergency DTMF string, the endpoint generates an emergency call and activates the emergency state. Until the emergency state is cleared, no further emergency calls from that subscriber can generate an Emergency Call.
