The XE0204 supplies two and four wire leased line connections, and complies with FCC Part 68 Rules for 2-wire connections to the public switched network. The XE0204 supports voice, data and fax transfer at speeds to 14,400 Bits Per Second, V.32bis data transfer over two wires and V.33 data transfer over four wires. The XE0204 is a complete DAA in a compact package. It includes the telephone line transformers, loop current holding circuit, ring detection, switch hook, two-to-four wire convertor and four-wire switch. The small size of the XE0204, just 1.5 square inches, allows the XE0204 to be used in most any application requiring connection to the telephone network.
