WTC-180
- Introduction of product
- VM(Voice Mux) of Wintech System Co. Ltd. is installed at subscriber network as integrated terminal device for subscriber circle and it is the device of transmitting by accommodating existing voice grade signal of subscriber, low velocity grade digital data, high velocity grade digital data and even SHDSL data and multiplexing them into DS1E(or DS1) signal. In addition, optimum system can be constructed by dividing the system into for 180 subscribers (WTC-180), 60 subscribers (WTC-60), and 30 subscribers (WTC-30) in accordance with the installation environment and subscriber capacity.
- Characteristice of product
- Improvement of stability through duplication of main circuit or function
- Reduction of spares and inventory through common use of channel unit
- Operating integrated unit in which similar functions have been synthesized
- Design of power supply in which operation is possible through battery even under the cutting off state of power
- Performing upgrade through EMS which does not cause any impediment to service
- Maintaining various information even under the cutting off state of power through the application of non-volatile memory
- Providing connection to ethernet network by CES
