When your system was planned, your Lucent Technologies representative made sure that it had a module to support one or more PFT telephones in case of an emergency. For more information, contact your Lucent Technologies representative.

NOTES:

1.The PFT jack does not operate unless a power outage occurs or the power supply units are turned off.

2.The PFT telephone can be any basic single-line telephone; a single-line telephone that is connected to an MFM cannot be a PFT telephone.

3.If rotary lines/trunks are in the system, you must use rotary telephones (500MMs recommended) as PFT telephones.
