Abstract
This invention is a transmission terminal station apparatus. The transmission terminal station apparatus is connected to a low-order group terminal device through a low-speed line and connected to a high-order group terminal station device through a high-speed line. The transmission terminal station apparatus includes a detection unit, a first insertion unit, a multiplexing unit, and a second insertion unit. The detection unit, when a frame is received from the low-order group terminal device, detects, as detection information, information related to operation maintenance information to be transmitted from the overhead of the frame to the high-order group terminal station device. The first insertion unit inserts detection information detected by the detection unit into a space area of the frame. The multiplexing unit generates a multi-frame including the frame. The second insertion unit inserts new operation maintenance information into an overhead of the multi-frame generated by the multiplexing unit to transmit the operation maintenance information toward the high-order group terminal station device.
