DATA COMMUNICATION SYSTEM |
摘要 |
The system includes a passive station dedicated to the control and acquisition of data of an electronic apparatus and arranged for communication with a central station over a non-dedicated voice band-width communication link with connections being established from the central station. The passive station includes means to initiate a call-out operation under alarm conditions, but the communication is limited to the establishment of the connection and the transmission of a ready signal to the central station inviting the central station to issue a command to the passive station to transmit information. |
