the form of simplex power. These voltages are hazardous and can cause death or
severe injury! Do not proceed with this installation if any voltage is present between
the send and receive pairs of the network interface. You can ask the serving telephone
company to temporarily disconnect the simplex power during installation.

power source, should AC power fail.
