Abstract
A transmission apparatus including: a plurality of asynchronous network interface units each having an asynchronous network termination unit for inputting/outputting a packet from/to an asynchronous networks and a mapping unit for converting the packet into a first synchronous frame and vice versa, a plurality of synchronous network interface units each used for inputting/outputting a second synchronous frame from/to a synchronous networks, a buffer provided on at least a first of the asynchronous network interface units, and a control unit for storing a packet output by the asynchronous network termination unit for accommodating a specific asynchronous networks and a packet output by the asynchronous network termination unit of the first asynchronous network interface unit into the buffer by adding identifiers for identifying the asynchronous network termination units in the event of a line failure occurring in a synchronous networks on a route related to the specific asynchronous network.
