Transmission apparatus equipped with an alarm transfer device

摘要

The present invention is directed to the provision of a transmission apparatus and, more particularly, of a transmission apparatus equipped with an alarm transfer device that enables alarm information to be transferred on a network where a protocol having a dedicated frame for achieving network management and client maintenance and a protocol that does not have such a dedicated frame are running in mixed fashion. The transmission apparatus, which is connected to the network where transparent data transmissions are performed using a plurality of client protocols, is designed to accommodate at least one of the plurality of protocols as a primary client protocol, and the alarm transfer device transfers alarm information indicating the occurrence of a failure to a destination transmission apparatus via the network, wherein the alarm information is transferred using an alarm frame created based on a prescribed client protocol unified among the plurality of client protocols.
