Module for SurePath Automatic Protection Switch (APS)

The Right Choice for T1 Network Protection

With just one card per end, the SUREPATH T1 APS continuously analyzes the incoming signal from two redundant Tl lines. Dependent on user selected criteria, the SUREPATH T1 APS provides the best incoming T1 line to the equipment.

In the event one of the incoming network lines exhibits out-of-frame, bit error rate beyond a pre-selected threshold, or loss of signal for any reason, the SUREPATH T1 APS automatically switches to the clearest line. The SUREPATH T1 APS ensures a viable Tl signal is passed when one incoming line is cut, suffers signal degradation or equipment failure.

SUREPATH T1 APS is also your cost effective choice - our one card-per-end system costs less than the two-per-end the competition supplies. The SUREPATH T1 APS also offers the industry's highest shelf density and doesn't require a dedicated shelf. The SUREPATH's distance capability is 3x better than the competition on the equipment and span sides.
