Secure Digital Intercommunication (SDI) System - 767 Tanker Program

"We required a proven, reliable kernel to support our mission critical application and the Nucleus PLUS kernel met all of our needs." --Steve Esposito, Vice President Business Development, Telephonics

Nucleus PLUS: Powering Telephonics' Aviation Communication System for 767 Tanker Program

Telephonics Corporation is a worldwide leader in integrated information and communication systems. Since entering the electronics industry in 1933, Telephonics has grown into a broad based, advanced technology company. Today, Telephonics continues to expand its business base by applying the technical know-how of its original defense communication and radar technologies to new electronic systems and products for a wide range of commercial and international customers.

Secure Digital Intercommunication (SDI) System

Telephonics newest intercommunication system, Secure Digital Intercommunication (SDI), is a fully digital/open architecture system with modular, scaleable configurations. SDI is designed for fixed wing aircraft, helicopters and ground shelter applications; providing high quality audio and secure communications capability - specifically designed to meet the customer's future requirements and offer additional value to their programs.

Nucleus PLUS Selected for the SDI in the 767 Tanker Program

At Telephonics, developers wanted a real-time kernel that had a proven reputation in the performance-critical market. Purchasing a kernel provided with source code and without royalty fees was important as well. After researching the RTOS market, Telephonics decided on Mentor Graphics' Nucleus PLUS real-time kernel for implementation in the SDI product.

The Nucleus PLUS kernel forms the basis of the secure digital intercommunication system, or SDI, of the 767 Tanker program. The SDI system is based on a new, zero occupancy Boeing 767-200 ER passenger airplane. The SDI consists of two interphone control units (ICU), programmed with the Nucleus PLUS kernel, that interface with each other and with peripheral equipment.

The SDI system has the capability to operate under domestic and international regulations in civil airspace, provide military communications capabilities, operate with a navigation database, perform formation and rendezvous flight maneuvers. In addition, it can perform 180-minute extended range, twin-engine operations (ETOPS-180), day or night, in low-weather minimum operation conditions, and perform precision landings at properly equipped airfields.
