0-1200bps, LEASED LINE

Telenetics has designed modems that work in "remote" remote sites with very low failure rates. These devices work where other modems roll over and die. When a service call to a remote site can mean an all day trip these modems are the ideal solution.

Bell 202T continues to be the standard of choice in many utility and industrial applications. The Telenetics MIU202T can be powered from a wide range of AC and DC voltages, is surge protected on both the power and telephone lines and will operate in extreme heat and cold. Ideal for both point-to-point and multi-drop applications over leased lines and private lines.

the MIU and MIU"PowerPort"202T

The MIU202T and MIUPowerPort202T are a Bell Standard 202T modem designed for asynchronous operation at 0 to 1800bps with C2 line conditioning, or 0 to 1200bps on unconditioned lines.

With the flip of a switch, the 202T modem can be configured for V.23 applications if required.

The 202 modem is intended for use on leased lines and private lines and provides half duplex communications on 2-wire lines, or full duplex communications on 4-wire lines.

Most modem manufacturers have abandoned Bell 202 modem in favor of the much higher speed modulations preferred in dial-up systems. However, Bell 202 remains the standard of choice in many utility and industrial applications where relatively small amounts of data are to be transmitted point-to-point or in multidrop networks.

The MIU202T modem version can be powered from any AC or DC voltage in the range 9V to 220V AC/DC  The MIUPowerPort202T has 9 to 12V power supply.  The 202T  is designed to work in extended temperatures ranging from -40oC to +85oC, and is surge protected to 8kV, double the voltage requirements of IEC801-4 Standard.

All of this is bundled in a 5-3/8" x 4" x 1-3/8" package, suitable for desktop or wall mounting. Rack mount cards are also available.
