The SLTi system allows addition of full duplex wireless head-
sets to most popular wired intercoms without complicated
and expensive base stations. The complete system consists
of a Simultalk 24G master transceiver, interface module, and
remote Simultalk 24G radios with headset. The interface in-
cludes a software driven circuit that matches the audio levels
if the wireless to that of the wired intercom.
The remote wireless user communicates with the wired party
line in a full duplex simultaneous talk format just as though
they were connected with an actual cable.
