XE0055S

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.

The XE0055S operates from a single power supply from +3 to +5 Volts. As with all Xecom telephone interface modules, internal ring indication and switch hook are provided.
