Power Fail Transfer (PFT)
When AC power to the system fails, back-up operation may be provided with back-up batteries
or Power Fail Transfer (PFT). When battery back-up is provided the station will operate
normally. When PFT is implemented, an SLT is connected to a CO line by the system. This
SLT can be used as any normal SLT, providing service while power is out.
