  • Cross connect apparatus capable of reducing workload of operator
    Patent number: 6535529
    Abstract: In a ring network, when a line setting operation is carried out, in order to simplify a cross connect setting operation, cross connect information into which information about a terminal NE and command information have been registered is transmitted from a transmission source NE, and this information passes through a node which is between terminal NE and terminal NE. Accordingly, a line setting manager is no longer required to perform a pass-through cross connect setting operation with respect to node which are between terminal NE and terminal NE, but merely transmits the cross connect information from the transmission source NE, so that the pass-though setting operation of the repeater NE and the cross connect setting operation of the terminal NE can be carried out.
