Korea Telecom has been leading the development of SDH (synchronous digital hierarchy)-based synchronous multiplexing and optical transmission equipment, and the result has produced 155/622/2488 Mbps equipment, which are named SMOT-1/4/16 (synchronous multiplexing and optical transmission system level-1/4/16), and those SDH equipment have been widely deployed to carry a huge amount of calls between telephone offices in Korea. Transmission equipment, by nature, are very stable, and require very little O&M (operation and management). For this reason, the SDH equipment developed in Korea have the minimal O&M function, which is to process inquiry and control commands from the operator's terminal serially connected to them. However, as the number of SDH equipment and their O&M terminals has been increasing every year, the need for centralized monitoring on SDH equipment has surfaced. By centralizing and replacing the existing O&M terminals by SMOT-IT, operators are able to access the rich statistical data that can not be provided by individual terminals. Also, it enables more efficient use of space in the transmission operator's room that has been excessively occupied by multiple terminals. The SMOT-IT has provided the solutions to the problems of the existing terminals, and therefore established centralized monitoring and efficient management on SDH equipment within a telephone office
