The TTC NSW-16GT-1 is a rugged 16-port Ethernet switch that enables multicast data to be accurately distributed between nodes with precise timing. Four of its ports provide 10GBASE-SR support with the rest providing 1000BASE-T. IEEE 1588 is supported (V1 or V2 configurable on a per-port basis) with an IRIG-B time code reader and generator, and a built-in battery-backed real-time clock and GPS receiver. The NSW-16GT-1 offers high levels of flexibility and functionality when instrumenting vehicles. It provides support for 10 GbE access to existing Curtiss-Wright solutions for applications such as flight test instrumentation, networked high-speed sensors, and 10 GbE data acquisition and recording.

The switch supports managed operation, allowing for dynamic configuration, statistics gathering and health monitoring using Simple Network Management Protocol (SNMP). Expansion is achieved by linking multiple switches together within the network, allowing additional data acquisition units, recorders and gateways. The NSW-16GT is optimized for size, weight and power (SWaP) and can operate with limited or no additional cooling. Other features include:

  • Full line rate non-blocking switching capacity
  • Support for port mirroring
  • Rapid and Multiple Spanning Tree Protocols (RSTP, MSTP)
  • Link aggregation (IEEE 802.3ad)
  • Jumbo frame support
  • IGMP v3 snooping
  • Support for port and tagged-based VLANs
  • Support for Quality of Service (QOS)
  • Supports TELNET and SSH (secure shell)
  • Field upgradable
