Abstract
A communication management system is consisted of a plurality of apparatuses connected to a network. Each apparatus comprises: a transmitter that transmits first setting information representing all setting status of own apparatus to the other apparatuses connected to the network; a receiver that receives second setting information representing all setting status of the other apparatuses connected to the network from the other apparatuses; and a storing device that stores the first and the second setting information. Desired data relating to all the devices connected to the network can be confirmed quickly.

- and
- a second slave setting device that sets, if the master confirming device confirms the existence of the master apparatus on the network, the communication management apparatus to be the slave apparatus without comparing the priority level of the communication management apparatus and the priority level of the master apparatus;
- a first transmitter device that transmits an audio data at a first transmission rate to the network;
- a first memory that stores a first status data representing setting status of the communication management apparatus;
- a second transmitter that transmits the first status data at a second transmission rate lower than the first transmission rate to the network;
- a first receiver that receives an order data generated by the master apparatus via the network, wherein the order data represents an order of transmission of the respective ones of the plurality of the communication apparatuses included in the audio data communication management system;
- a third transmitter that transmits a first modification data indicating modification of the first status data at an order specified by the received order data;
- a second receiver that receives a second status data representing setting status of at least one of the other communication management apparatuses at the second communication rate from said one of the other communication management apparatuses via the network;
- a second memory that stores the received second status data;
- a third receiver that receives a second modification data indicating modification of the second status data from said at least one of the other communication management apparatuses;
- and
- a modifying device that modifies the second status data stored in the second memory in accordance with the received second modification data.
