Span Power and Protection


The SPW system reduces service outages via transient protection. The unit is installed between a mulitplexer and a remote T1 NIU chassis. The SPW can provide span power to the remote T1 NIU chassis, eliminating the need for local power at the T1 NIU chassis. In addition, the SPW provides lightning and power cross protection for the mulitplexer as well as remote alarm reporting.
