The accessory is supported by the following sets
The external ringing interface module allows driving an external system (like a ring or a lamp), following
the ring tone cadence of the phone set connected on the telephone line. A switch on the electronic board
allows selecting between 2 operation modes.
• Follows the cadence: the relay follows exactly the ring signal.
• Hold mode: the relay is held for 0,7 s after the ring signal is gone. It erases some of the
ring pulses.
