2-Wire/4-Wire Telephone Line Interface

Description

The XE0204 provides a common telephone interface

for networks integrating two and four-wire telephone

connections. 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.
