T1 / E1-over-IP Gateway (1-4 ch.)

Rollover or Touch for Expanded View. Scroll to Zoom.


This T1/E1 over IP device transports up to 4 channels of T1 or E1 over Layer 2/3 Ethernet networks with low latency. It is part of the JumboSwitch® series, a TDM over IP/Ethernet based solution designed to emulate time-division multiplexing over packet switched networks (PSN).

Typical applications for the TC3845-1 are the replacement of copper T1/E1 lines as well as the connection of existing T1/E1 based channel banks often as part of a network migration.

Migrating T1/E1 using JumboSwitch positions a user for complete channel bank replacement with JumboSwitch at a future date.

  • Transports 4 Ch. T1/E1 Over Ethernet/IP
  • Extremely Low Latency
  • Point-to-Point & Point-to-MultiPoint Applications
  • VLAN and QoS Support
  • Manage Via Web, SNMP, Serial Console, Telnet
  • Built-In Temperature & Power Sensors
  • Extreme Temp (-40°C to +80°C) 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 TC3845-1 is used to extend T1/E1 links between PBX’s, connect video conferencing, or link Cell Towers to Central Offices, all over existing Layer 2 / Layer 3 Networks.
