Network Extension Device (NED)
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.
