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.
