Featured Product from GL Communications, Inc.

Following are GL product offerings in carrier ethernet test tools –

  • PacketExpert™ 1G (PXE100) - Available in Portable
  • PacketExpert™ 10G (PXG100) - Available in Portable only
  • PacketExpert™ 10GX (PXN100) - Available in portable (PXN100) and Rack (PXN1XX) variants

All these PacketExpert™ platforms support multiple functionalities for carrier-grade ethernet testing as listed below –

  • Wire speed BERT
  • Smart Loopback
  • RFC 2544 Testing
  • Record and Playback
  • Y.1564 (ExpertSAM™)
  • PacketBroker – (Tap-Filter-Modify-Aggregate Packets)
  • Multi Stream UDP/TCP Traffic Generator and Analyzer
  • RFC 6349 (ExpertTCP™)
  • WAN Link Emulation – IPNetSim (Multi-stream)/ IPLinkSim (Single-stream)

PacketExpert™ 10GX, a multi-functional ethernet tester supports all interfaces, functionality and port capacity similar to that of previous PacketExpert™ 10G for comprehensive testing of 10 Gbps /1 Gbps wirespeed Ethernet/IP networks.

With the capability to generate/receive traffic with stacked VLAN (Q-in-Q) and stacked MPLS, PacketExpert™ 10GX finds use in testing a wide range of networks – from testing individual links/switches, testing local Ethernet/IP networks (LAN), end to end testing of Wide Area Networks (WAN), testing Core/MPLS networks, and much more.


  • Multiport Ethernet Switch Testing
  • Test and verify QoS Parameters of network devices like Switches/Routers etc.
  • End to end testing of network paths for QoS parameters
  • In-depth troubleshooting of the Carrier network in the event of network failures or impairments
  • QoS testing of Triple-play services to ensure that they fully qualify SLA parameters
  • Terrestrial wireless, satellite, and other WAN technologies network validations.
  • Test VoIP network in real-time conditions to verify if it meets the quality requirements before you deploy.
  • Test routers, switches, VoIP handsets, VoIP PBXs, set-top boxes, and VoD servers

Common Features

  • Capable of simultaneous generation /reception of Ethernet to IP traffic at 100% at user-defined or auto-negotiated speed
