About Telephone

Campbell Scientific offers three types of modems for telephone communication. Rugged land-line modems are ideal for field use. Digital cellular modems provide an alternative for mobile applications or locations where ordinary phone lines are not a practical option. Voice-synthesized modems enable users to access their data via voice or to send their data to a computer.
