First Claim
1. An intelligent terminal which primarily functions to deliver a predetermined product or service, the terminal including means for monitoring the status of its primary function, means for automatically answering incoming telephone calls, means for automatically dialing a selected telephone number from a first group thereof, and means for controlling the operations of said terminal in accordance with stored instructions, characterized by:
- means for reporting the status of its primary function to another intelligent terminal;
means responsive to control information received over a communications link for replacing the stored instructions with a new set thereof; and
means responsive to control information received over the communications link for replacing the first group of telephone numbers with a second group thereof, said first and second groups of telephone numbers being associated with other intelligent terminals;
whereby the reporting relationship of a network of intelligent terminals can be remotely configured.

Abstract
A microprocessor-controlled coin telephone station includes apparatus that enables it to provide dialed telecommunications service and accept payment therefor--which is its primary function. The coin telephone station further includes apparatus for automatically dialing predetermined telephone numbers, automatically answering incoming telephone calls, and apparatus for monitoring conditions associated with its primary function in order to be a participating member of a hierarchal reporting network--which is its secondary function. In order to carry out the secondary function, the coin telephone station stores operating instructions which cause it to operate as either a Master or a Slave station within the hierarchal network. The operating instructions are downloaded into the telephone station from a Host computer over the Public Switched Telephone Network, which enables it to remotely reconfigure its hierarchal network of telephone stations to efficiently accommodate additional stations and periodic changes in the cost of long distance telephone calls.
