FDSL-R12
- Introduction of product
- For FDSL II-R12(Fractional Digital Subscriber Line II) device, in the case of 4 wire type, the signal which is comprised of the data with the maximum of 768Kbps can be transmitted up to the maximum of 5Km(0.4mm) without repeater, and the NxDS0 subscriber signal can be multiplexed or demultiplexed into the DS-1(E) signal by accommodating up to the maximum of 12 sheets of various DSL subscriber units, and this is the device with which NxDS0 subscriber signal can separately be operated in accordance with the requirement.
In addition, by utilizing E1/T1 unit, E1/T1 signal can be tranmitted up to the maximum of 4Km(0.4mm) without repeater.
- Characteristice of product
- In the case of 4 wire type, transmission is possible up to the maximum of 5km(0.4mm) without repeater
- Compatible connection with existing FDSU(64CAP) is possible.
- Self diagnosis is possible without measuring instrument through various LoopBack and TPG.
- Current state of device can be monitored through LCD & LED.
- Remote control function with which subscriber side device can be controlled at remote location
- Network can efficiently be constituted with multiplexing and demultiplexing function through Trunk Unit.
