A telecommunication system incorporates individual station instruments
simplified by wireless operation, voice dialing, prepaid accounting and
out-call operation, all enabled by cooperative system operation including
supporting central equipment. Wireless operation of the central equipment
involves a multiple port wireless platform along with other units for
interfacing a multitude of mobile station instruments simultaneously for
interactive audio communication to, regulate control, monitor and record
operations of the instruments, and bridge communication with selected
remote terminals through the public switched telephone network. Message
capability, emergency abort to an operator station and security features
supplement the basic system. Communication is controlled for the
individual instruments to be either voice or dial-up signals. Voice
recognition units alternatively are located in the central equipment
and/or the individual station instruments and controlled accordingly.
Manual control at instruments accommodates either voice or number outgoing
communication.
