Abstract
A transmission apparatus comprises a main signal line block for transmitting a main signal and a monitor/control block for monitoring state of the apparatus and lines by collecting line switching information supplied from each unit which constitutes the main signal line block and controlling the switching operation between a working line and a protection line. The main signal line block and the monitor/control block are connected by an ATM link. An ATM routing unit in the main signal line block collects line switching information supplied from each unit and maps the line switching information in data portion of an ATM cell and transmits the ATM cell to the monitor/control block via the ATM link.
