The TG8 narrowband, binary FSK modulated modem is an excellent solution for reliable transparent data transmission over voice-grade communication channels even in poor transmission conditions. Type of modulation used (binary FSK) ensures high immunity to interference, noise and other types of disturbances.
Main features
- Fully programmable data transmission rate and channel central frequency - fully complies to R and V series of ITU-T international standards
- Integrated line switchover function – simultaneous transmission over main and backup line
- Integrated amplitude equalize – equalization of attenuation distortion of communication cable
- Single card design – complete transmitter and receiver including data interface and doubled line interface (line switchover function)
- Equipment housed separately or integrated in to the PLC equipment ET8
- Member of PLC 2000 Communication system
