    Description

    Compatible with PBXs & Key Systems, the TC1900 "Quick-Talk" Phone Extender extends voice over Async RS-232 into a voice network by plugging in an analog telephone.
    The TC1900 "Quick-Talk" RS232 Phone Extender extends dial-up phone service to remote sites over Async RS-232. Compatible with most PBXs or Key Systems, it provides 2-wire FXS on the telephone side with ring down capability and FXO on the PBX side.

    Quick-Talk is typically used to extend dial-up phone service to remote sites over a RS-232 circuit (TC1900). Other examples include extending a secured phone link to a remote site via an existing RS-232 connection or setting up "hot links" via existing RS-232 links on satellite, fiber optic or microwave networks. When both sides are set to FXS, a "Hot Link" can be established.

    The TC1900 supports toll quality voice, asynchronous baud rates from 19.2K and bandwidths from 300Hz to 3.4Khz. Sixteen diagnostic LEDs and a Dry Contact for External Alarm and Ringer Connection are standard.
