Data and Voice for European Power Company

Situation

A European power company needed reliable, sensibly priced equipment to set up a data and voice communication system between power stations.

Solution

Loop-AM3440A units equipped with E1, FXS, FXO and RS232 cards were installed at each node on the network. This setup included E1 1+1 protection for reliability. The RS232 was used for general SCADA tools. The AM3440 also supports terminal server functionality through a separate card.

Exceptional service and communications reliability were achieved at a reasonable price. V.35/X.21 and E&M cards were easily added later to meet unexpected communication requirements.

The Loop-AM3440A also supports 4 LS Fiber Optical Interfaces in the C37.94 format that are common in the power industry. The C37.94 supports teleprotection via optical fibers, while a codirectional G.703 card can be used for copper wire protection.
