Tip Feed.
Connects to external diode for protection
Loop Ground
. Is the system ground reference with respect to V
BAT.
Normally connected
to AGND.
Voice Receive (Input).
The 4 wire analog signal to the device.
Internal Connection.
No connection should be made to this pin
Negative Power Supply Voltage (-5V).
Analog Ground.
Connects to System Ground (Earth).
Power Denial (Input)
. A logic high will isolate the battery voltage to Tip/Ring.
Voice Transmit (Output)
. The 4-wire analog signal from the device.
Tip Lead
. Connects to the "Tip" lead of the telephone line.
Ring Lead.
Connects to the "Ring" lead of the telephone line.
Ring Feed (Input).
Normally connected to Ring relay for negative battery feed voltage and
ringing voltage input.
Positive Power Supply Voltage (+5V).
Relay Control (Input)
. Active high.
Relay Drive.
Open collector sinks current when RC is at logic high.
Ring Feed Voltage.
Normally connected to pin 11 (RF) through a normally closed relay
and to external diode protection.
Relay voltage Supply (+5V).
Clamping Diode
. Normally connected to AGND.
Negative Battery Feed Supply Voltage (-48V).
Battery supply for the Subscriber Line.
Typically -48VDC is applied to this pin.
Ring Trip Filter Capacitor.
Normally connected via an external capacitor to ground to
prevent false ring trip. Must be open circuit to allow dial pulse detection.
Switch Hook Detect (Output).
A logic level 1 will indicate that the Subscriber Line is in
the ’Off-Hook’ state.
