Minature V.34 Telephone Line Interface

Description

The XE0055S and XE0055T are very slim

telephone interface modules. They support

V.34 communications at 28,800 bps, yet are

no more than 0.290 inches thick and comply

with FCC Part 68 Rules for connection to the

public telephone network.

The XE0055S and XE0055T differ only in

their Ring Indicate outputs. The XE0055S

provides an integrated RI output. It remains

low while ring is present. The XE0055T's RI

output is not integrated. It provides a pulse

train at twice the ring frequency.

Xecom offers two mechanical variations of

the XE0055S and XE0055T. The XE0055S1

and XE0055T1 mount vertically to consume

minimal board space. The XE0055S2 and

XE0055T2 mount horizontally for

the lowest possible profile. Both

versions have the same pin out and

are electrically identical.
