Rollover or Touch for Expanded View. Scroll to Zoom.


JumboSwitch® offers an Ethernet-over-T1/E1 card that connects a JumboSwitch® network or any third party Ethernet networks over existing T1/E1 circuits.

The JumboSwitch® series is a TDM over IP/Ethernet based solution designed to emulate time-division multiplexing over packet switched networks (PSN). TDM over IP/Ethernet is a TDM pseudowire (PW) technology making it possible to provision E1, T1, E3, T3, STS-1 and serial data services across PSN's such as IP, MPLS or layer 2 Ethernet Networks.

  • Fast Ethernet Transport over Framed & Unframed T1 or E1
  • IEEE 801.p QoS with Four Queues
  • Ethernet and T1/E1 Statistics Monitoring
  • VLAN Tagging and Priority Labeling
  • Manage Via Web, SNMP, Serial Console, Telnet
  • Built-In Temperature & Power Sensors
  • Extreme Temp (-40°C to +80ºC) Optional
  • Meets or Exceeds IEC 61850-3, IEEE1613 & NEMA TS-2 Standards
  • Member of the JumboSwitch® Product Family


  • Bridging Ethernet LANs over Existing T1/E1 Telecom Network
  • Extending Ethernet Networks by Utilizing TDM Telecom Infrastructure (i.e. T1/E1 Landline, or T1/E1s/SDH Microwave Carrying T1/E1)
  • Demarcation Between the Carrier’s and Customer’s Networks
  • Bonded Transparent LAN Service
