ABSTRACT:
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.
