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.
