Method of sending and receiving setting information and monitoring information in communication apparatus

摘要

Disclosed is a method of sending and receiving setting information and monitoring information between a monitoring controller and units which construct the multiplexing section of a communication apparatus. In a case where setting information is transferred from the monitoring controller to a prescribed unit, the monitoring controller time-division multiplexes the setting information for the unit and enters the information into a time switch via an incoming line. The time switch switches the time slot position of the setting information and sends the setting information to an outgoing line corresponding to the unit. The unit drops the setting information from the time slot. Further, in a case where monitoring information is transferred from a unit to the monitoring controller, the unit time-division multiplexes the monitoring information to a predetermined time slot and enters the monitoring information into the time switch from a prescribed line. The time switch switches the time slot position of the monitoring information and sends the monitoring information to the monitoring controller via an outgoing line. The monitoring controller accepts the monitoring information from the unit, with the information coming from the above-mentioned time slot.
