T3 / E3-over-Ethernet ( DS3-over-Ethernet ) or Enterprise Networks

Rollover or Touch for Expanded View. Scroll to Zoom.


This T3/E3 over IP Gateway transports a single T3 or E3 circuit over Layer 2/3 Ethernet networks with low latency.

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.

  • Jitter complies with G.823 and G.824 standards.
  • Transports 1 Ch. T3/E3 Over Ethernet/IP
  • Extremely Low Latency
  • Point-to-Point Applications
  • VLAN and QoS Support
  • Manage Via Web, SNMP, Serial Console, Telnet
  • Temperature & Power Consumption Monitoring
  • Extreme Temp (-40°C to +80ºC) Optional
  • Meets or Exceeds IEC 61850-3, IEEE1613 & NEMA TS-2 Standards
  • Member of the JumboSwitch® Product Family


Typical applications include transporting voice, video, and data across IP networks.

For example, the TC3845-3 is often used to extend T3/E3 links between PBX’s, connect video conferencing or link Cell Towers to Central Offices.

It is also used to extend T3/E3 links between M13 multiplexers and Routers.
