Tip Lead.
Connects to the “Tip” lead of subscriber line.
Ring Lead
. Connects to the “Ring” lead of subsriber line.
No Connection
. This pin may be used for internal connections.
DC Ringing Voltage Input
. A continuous 120 Vdc is applied to this pin. This voltage is the
positive supply rail for the internal ringing amplifier for subscriber line.
Battery Ground
. V
Bat
return path for subscriber line. Connects to the systems’s energy
dumping ground.
Battery Voltage
. Battery supply feed for subscriber line. Typically -48Vdc is applied to this
pin.
No Connection
. This pin may be used for internal connections.
Positive Supply Voltage
. +5V dc supply rail.
Analogue Ground
. V

return path.
Negative Supply Voltage
. -5V dc supply rail.
Ringing Control
. This input enables the ringing voltage feed to Tip and Ring for subscriber
line.
Power Denial.
A
logic
high will isolate the battery voltage for Tip and Ring.
No Connection
. This pin may be used for internal connections.
Switch Hook Detect.
A logic high indicates when subscriber line has gone off-hook.
Receive Signal.
This is the 4 wire analogue signal received at subscriber’s set.
Reference Voltage.
A dc reference voltage is applied to this pin to set the constant current
feed to subscriber line. This pin may also be grounded for normal 25mA loop current.
Ring Trip Filter Capacitor.
A capacitor is normally connected from this pin to ground and
filters out low frequency ringing signals, preventing false off-hook conditions.
