Slim V.34 Telephone Line Interface with 2/4 Wire Hybrid
Description
The XE0052S and XE0052T are compact telephone in-
terface modules which support V.34 communications at
data rates to 33,600 bps yet are just 0.31 inches thick
and comply with FCC Part 68 Rules for connection to
the public telephone network.
The XE0052S and XE0052T are complete DAAs.
They include the 2-4 wire convertor to separate trans-
mit and receive signals, ring detection, and the switch
hook to control line access. The two models differ only
in their RI outputs. The XE0052S has an integrated RI
output which remains low for the duration of the ring.
The XE0052T RI output is not integrated and provides
a pulse train at twice the ring frequency.
Xecom offers two mechanical variations for each of the
XE0052S and XE0052T. The XE0052S1/T1 mount
vertically to consume minimal board space. The
XE0052S2/T2 mount horizontally to maintain a low
profile. Both versions are electrically identical and
share the same pin configuration.
