Ring connection to the phone line (RJ11 Pin 4). The Ring pin has 1500 volts
isolation from the rest of the circuitry. This isolation must be preserved
throughout the system.
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 equipment to the telephone line.
TX provides the analog input signal to the 2-4 wire convertor of the
XE0052S1. TX uses a 2.5 volt reference signal and therefore must be
capacitively coupled to the host equipment.
Ground
+5 Volts supply power
RX provides the analog output signal from the 2-4 wire converter of the
XE0052S. RX uses a 2.5 volt reference signal and therefore must be
capacitively coupled to the host equipment.
Ring Indicate, output, active low, TTL. A low on /RI indicates the modem is
receiving a ring signal.
