Extend the Reach of your Network with High-Performance Onboard Connectivity
Teledyne Controls' Network Extension Device (NED) is a high-performance and compact networking solution that facilitates data transfer between avionics systems and IP-based equipment, providing greater accessibility to a wide range of applications. This high-reliability device, built to OEM standards, combines the multiple functions of an ARINC 429 to Ethernet converter, multicast router, firewall, data loader and communication gateway, in one single and lightweight unit. The NED can support a variety of applications, such as distribution and loading of software parts and Electronic Flight Bag (EFB) operations. In essence, the NED facilitates high-capacity collection and distribution of critical aircraft data for operations, maintenance and flight safety purposes.

Extensive Networking Functions
Designed to support extensive networking infrastructures, the NED interconnects previously isolated onboard systems and sub-networks with various Ethernet wired interfaces, while enforcing network security with its firewall functionality. The NED acquires, processes, stores and distributes data for multiple systems and applications. It can also manage Quality of Service (QoS), allowing operators to prioritize traffic for critical applications.

Flexible Communication Gateway
Off board communication is also available through the NFS. The system can manage and interface with a variety of communication systems and high-speed links to provide connectivity between the airplane and the airline's ground networks. For example, the NFS can connect to ACARS and Swift Broadband SATCOM systems for in-flight communications, and interface with a wireless solution such as Teledyne's Wireless GroundLink® System (WGL) for ground-based connectivity.

ARINC 615-4 Data Loading
The NED integrates a full 615-4 data loader, to streamline operator's data loading processes by eliminating the need to reproduce, distribute and load countless floppy disks every month. When using the NED with Teledyne's WGL system and LoadStar® Server Enterprise (LSE) ground-based software, operators can fully automate the electronic distribution and loading of software parts across their fleet.

OEM Qualified Device
Teledyne's NED is a high-performance networking system designed to stringent Boeing OEM standards. As a result, the NED meets rigorous requirements for functionality, reliability and performance in severe environmental conditions. This high-caliber system is standard on Boeing 747-8 aircraft and delivers the long-term dispatch reliability that operators expect from avionics class equipment.
