WTM020
- Introduction of product
- WTM020 is the device of transmitting various signals of subscriber (DS1, DS1E, DS3, EOS) by multiplexing them into OC1 signal. In addition, optimum system can be constructed by dividing the unit in accordance with subscriber capacity and type of signal.
- Characteristice of product
- Duplicated structre of main unit and automatic protection transfer function
- System operation and monitoring function through GUI
- Remote control function through DCC
- Self diagnosis fuction through various LoopBack and performance information
- State information indication function through front LED and audible alarm
