WTM-060 plus
- Introduction of product
- WTM060 is the device to tranmit various subscriber signals (DS1, DS1E, DS3, EOS, Ethernet) with STM-1 signal by multiplexing them.
This is the device of performing demulitplexing and circuit distribution function by connecting to branch office device (COT) with STM1 signal.
This device is divided into WTM-3DS3 and WTM-63DS1(E)/3DS3.
- Characteristice of product
- Conforming to the technical standards of SDH & PDH of ITU-T
- Accommodation of exclusive use of DS3 signal of WTM-3DS3 and mixed use of DS3/DS1(E) signal of WTM-63DS1/3DS3 and ethernet signal are possible.
- Duplication structure of main unit and automatic protection transfer function
- System operation and monitoring function through GUI
- Remote control function through DCC
- Self diagnosis function through various LoopBack and performance information
- State information indication function through front LED and audible alarm
