DESCRIPTION
from the rest of the circuitry. This isolation must be preserved throughout the system.
The XE0017 is not polarity sensitive.
Tip Connection to the phone line (RJ11 Pin 3). The Tip pin has 1500 volts isolation
from the rest of the circuitry. This isolation must be preserved throughout the system.
Hookswitch relay control. A high on OH closes the internal relay and connects the equip-
ment to the telephone line.
nal. /RI provides a square wave representation of the Ring signal present at Tip and
Ring.
RX provides the analog output signal from the 2-4 wire converter of the XE0017.
