Intraplex NetXpress IP/T1/E1 Multiplexer 

The Intraplex® NetXpress™ IP/T1/E1 multiplexer takes voice and data transport to a new level of performance and reliability. It provides transport over packet networks for a wide range of real-time applications critical to public safety. As the industry’s best platform for public safety systems requiring transport over IP, NetXpress™ offers system-level resiliency, sophisticated network monitoring and excellent bandwidth management. NetXpress™ delivers the quality of Intraplex® and the economy of IP in one solution.

NetXpress™ is a superior solution for public safety applications such as land mobile radio systems, video surveillance, monitoring of remote sites and emergency backup of circuits.

  • Voice, data, and video transport over IP networks
  • Multiple service transport in one or more streams
  • Simulcasting over IP with SynchroCast3™
  • Smooth migration to packet-switched networks
  • Built-in forward error correction (FEC), packet delay jitter compensation and low-delay packet processing
  • Ability to use existing communications infrastructures
  • Simultaneous IP & T1/E1 operation
  • Browser-based graphical user interface
  • SNMP interface for connection to network management systems


The base system includes the chassis with one Network Interface Module (NIM), one Module Interface Unit (MIU), and one power supply. Hot-standby redundant NIM and power supply optional.
