TC1900/1
Async RS232 or Fiber Telephone Extender (''Quick-Talk'' POTS-to-RS232 or Fiber)

The TC1900/1 "Quick-Talk" RS232 or Fiber Phone Extender extends dial-up phone service to remote sites over Async RS-232 or Fiber. 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 fiber optic (TC1901) or RS-232 circuit (TC1900). Other examples include extending a secured phone link to a remote site via an existing RS-232 or Fiber 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 TC1900/1 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.

Applications

The TC1900/1901 is often used to extend telephone service in campus networks, power plants, substations, etc or use an existing service data channel to set up a telephone link. It is also used to set up "hot" telephone service via existing RS-232 links on satellite, fiber optic or microwave networks. Other applications include using the inherent benefits of fiber optics to reduce noise/EMI or maximize security/isolation.
