FDSL-768
- Introduction of product
- FDSLIII (Fractional Digital Subscriber Line III) can send signal by up to 4Km (0.4 mm) without repeater in case of four-wire by using data of maximum 1544bps in CAP method . It can multiplex and de-multiplex NxDSO subscriber signal into DS-1E signal by accepting various DSL subscribers and if needed, it can separately operate NxDSO subscriber signal.
Moreover, it can send E1/T1 signal by up to 4Km (0.4mm) without repeater using E1/T1 unit.
- Characteristice of product
- Transmission up to 5km (0.4mm) is possible without repeater in case of four-wire
- Compatible access is possible with existing FDSDU (64 CAP)
- Self diagnosis is possible without measuring instruments by various loopback and TPG
- Monitoring current state of device is possible by LCD and LED
- Remote control function that can control subscriber device in remote
- Function of composing effective network by function of multiplexing and demultiplexing by trunk unit
