Abstract
A communication network includes a first communication device (10, 64), a second communication device (14, 66) connected through a switched network (12, 68) to the first communication device (10, 64), in order to carry out a communication with the first communication device (10, 64), and a monitor/management device (16, 60) for performing a monitoring and/or management of the first and the second communication devices. In a first embodiment of the present invention, a disconnection factor requiring a disconnection between the first and the second communication devices is detected in the second communication device, and is transmitted to the first communication device, and thereafter, a connection between the first and the second communication devices is disconnected. In a second embodiment of the present invention, monitor/management information from the monitor/management device to the second communication device is once retained in the first communication device and is transmitted to the second communication device while both are connected to thereby carry out a user communication. Monitor/management information from the second communication device to the monitor/management device is transmitted to the first communication device while both are connected, and once retained in the first communication device.
