2013 - Paraguay Power Company Deploys JumboSwitch as Lower Cost Alternative to SONET/SDH System

The solution that fulfilled all of ANDE’s requirements was the JumboSwitch Multi-service Ethernet Platform.

Costing less than a comparable SDH/SONET system, the JumboSwitch provided all of the required interfaces for ANDE’s applications: Ethernet, Teleprotection (RS232), E1 over IP and VOIP with virtual PBX capability.

In addition, the JumboSwitch system offered a comprehensive network management system, “TCView,” that helped technicians with minimal training to deploy, maintain and reconfigure a JumboSwitch network.

For example, configuring a point-to-point Teleprotection circuit with the JumboSwitch is a simple matter of programming the source IP address to the destination IP address. (Conversely, configuring this same circuit on a SDH/SONET system is more complicated and time consuming).

The installation went smoothly. ANDE deployed the JumboSwitch’s E1 over IP card to link to its Remote Terminal Units (RTU); the “Turbo serial” RS232 low latency card for Teleprotection relays, and the VoIP card to enable voice communications between the substations and back to the central office.(See diagram below).
