Abstract:
A method for supervising a first logical connection of a transmission system, the transmission system including a bidirectional transmission line and at least two physical components coupled to the transmission line, each of the physical components including at least one logical component, the method comprising the steps of:allocating an address to the at least one logical component, the address corresponding to a function of the at least one logical component; transmitting a request by a first logical component of the at least one logical component of one of the physical components for establishing the first logical connection between the first logical component and a second logical component of the at least one logical component of another one of the physical components; and providing the first logical connection between the first logical component and the second logical component using the second logical component, the first logical component performing a monitoring function and a control function for the first logical connection, one of the first logical component and the second logical component performing a termination function for the first logical connection; wherein the first logical component assumes a master status with respect to the first logical connection, and in response to a request, concurrently assumes a slave status with respect to a second logical connection.
