    Description

    The TC1901 "Quick-Talk" Fiber Optic Phone Extender can turn a fiber optic network into a voice network simply by plugging in a telephone set.
    The TC1901 "Quick-Talk" Fiber Telephone Extender extends dial-up phone service to remote network sites. It is compatible with most PBXs or Key Systems and provides 2-wire FXS on the telephone side with ring down capability and FXO on the PBX side.

    The TC1901 is typically used to extend analog telephone service in campus networks, power plants, substations where ground loops, noise, EMI or security issues may exist. Other examples include extending secured telephone links or setting up "hot links."

    The TC1901 provides Toll Quality voice and often improves voice quality when compared to twisted pair circuits. It supports asynchronous baud rates from 19.2K and bandwidths from 300Hz to 3.4Khz.
