Title:
伝送装置、伝送システム及び遅延調整方法
Document Type and Number:
Japanese Patent JP7041356
Kind Code:
B2
Abstract:
A transmission apparatus performs communication with a transmission side transmission apparatus via a transmission path of an active system and a transmission path of a standby system. The transmission apparatus includes: a memory configured to have a capacity that is as large as delay caused due to a maximum path difference between the transmission path of the active system and the transmission path of the standby system is allowable; and a memory connection control unit configured to switch connection of the memory and cause a signal of the transmission path of the active system or the transmission path of the standby system to be accumulated in the memory.
