Ethernet / IP-over-T1/ E1


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.

For assistance with this product or to request a user manual please contact Technical Support.
