Transmitter set includes CD with MIB files, which ensure binding of controlled parameters of the transmitter to the NMS.
Installation example
There is a recommended installation example when it is necessary to ensure a high reliability of optical system. For this purpose a power supply UP412
is recommended, as it is designed for operation in parallel connection to ensure the back-up function.
The server of transmitter has an additional useful feature to receive data from up to two UP412 power supplies. In this case the server of optical transmitter
works as a network element controller, which polls equipment that is connected to the data bus.
Therefore, the web browser allows supervising and controlling the function of the transmitter and power supply UP412.
