G.703/64K-over-IP Gateway

Rollover or Touch for Expanded View. Scroll to Zoom.


The G.703/64K-over-IP Gateway Card achieves less than 5 msec. latency by adaptive clock recovery, buffering and forwarding technology.

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.

  • Extends G.703/64K Co-directional Interface over Ethernet
  • Less Than 5 msec. Latency, One Way
  • 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 +80ºC) Optional
  • Meets or Exceeds IEC 61850-3, IEC 60834, IEEE1613 & NEMA TS-2 Standards
  • Member of the JumboSwitch® Product Family


Typical applications include extending G.703 circuits across IP networks. For example, the TC3846-1 is used to extend Teleprotection relays with a G.703/64K interface over existing Layer 2 / Layer 3 Networks.
