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 circut 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.
