Apparatus and method for generating synchronous multiplexing frames including TUG3/STS3 and TUG2/VTG channels

摘要

A payload data generating portion (21) generates payload data to be inserted into a frame structure of each of a TUG3/STS3 channel and a TUG2/VTG channel at a payload portion of a synchronous multiplexing frame. A payload structure setting portion (40) sets a frame structure of each channel which is included payload data to be inserted into the payload portion to a desired structure according to arbitrary setting of an operating portion (35), including the TUG3/STS3 and TUG2/VTG channels. This setting portion also lists and displays in a desired mode on a display (36) the frame structure of each channel including the payload data generated by the payload data generating portion (21), including the TUG3/STS3 and TUG2/VTG channels. A frame generating portion (30) multiplexes the payload data and inserts the multiplexed data into the payload portion, and adds a header portion to the payload portion to generate the desired synchronous multiplexing frame.
