4.0 Making A Power Failure Station Connection
Every loop start line board provides a tip and ring pair connected to line 1 as an emergency power failure circuit.
This power fail circuit is active during a commercial AC power failure if an external battery assembly is not
installed to provide battery back-up power to the system. Connect an industry standard, single-line telephone to
the power failure jack and use it to provide basic communications capability until the AC power to the system is
restored. The bottom jack on the line board provides the power failure connection.
