TNW1SL64S Is Huawei OptiX OSN 1800 SDH Optical Interface Board
Huawei OptiX OSN 1800 SDH Optical Interface Board TNW1SL64S Overview
TNW1SL64S: 1 x STM-64 line board
The board TNW1SL64S is directly controlled by the CPU unit on the system control and communication unit. The CPU unit issues configuration and query commands to the other units of the board over the control bus. These units then report command responses, alarms, and performance events to the CPU unit over the control bus.
The logic control unit decodes the address read/write signals from the CPU unit of the system control and communication unit and enables FPGA loading.
The TNW1SL64S consists of an O/E conversion unit, an overhead processing unit, a logic control unit, and a clock unit.
The TNW1SL64S Receives/Transmits 4 x STM-16 optical signals.
