The NSW-8GT-TGE-1 provides packet switching and the IEEE 1588 time distribution necessary to support networked data acquisition components.

The switch supports managed operation, allowing for dynamic configuration, statistics gathering, and health monitoring using Simple Network Management Protocol (SNMP). IEEE 1588 is supported with an IRIG-B time code reader and generator, a built-in battery-backed realtime clock, and a GPS receiver.

Additional Features

  • Port capabilities and media include ports 1-8: 10/100/1000BASE-T
  • Full IRIG-106 Chapter 21-28 TmNS support, including MDL programming
  • Built-in GPS receiver, IRIG-B time code reader and generator for IEEE 1588 grandmaster clock operation
  • Synchronizes IRIG time from 1588 time / vice-versa
  • 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)
  • Configurable via TTCWare, TmNS MDL, CLI, and a web page
  • Field upgradable
  • Compatible with Curtiss-Wright networked acquisition and recording systems
