摘要:
To interface a primary telephone terminal with a vast number of remote terminals through a telephone network, parties at the remote terminals are individually screened to attain a select group. Bridged together, the select group is preliminarily informed of the status of the interface by a voice generator and, accordingly, the multitude of connections are synchronized for the interface. On cue, the select group is coupled to the primary telephone terminal for unilateral communications. Deviations from the unilateral communication include select bilateral communication for a few of the remote terminals and digital communication from the remote terminals by push button as for polling applications. Subjects for interfaces are programmed for selection from a memory.
