Loop Closure Filter Capacitor. PPM injection can cause false loop closure indication.
Connect a capacitor from this node to V
sure filtering is not required, leave this node open.
Battery Ground. Ground return for the battery supply.
Auxiliary Battery. If a lower-voltage auxiliary battery is used, connect the auxiliary bat-
tery supply to this node. If a power control resistor is used, connect the power control
resistor from this node to V
to V
Office Battery Supply. Negative high-voltage power supply.
Office Battery Supply. Negative high-voltage power supply.
Battery Ground. Ground return for the battery supply.
Test Input. This input injects a test signal to the line when an appropriate test operational
state is chosen. Connect this node to V
Connect to V
Test Level Output. This output pin will provide a voltage that is proportional to either the
dc line voltage, dc line current, ac line voltage, ac line current, or internal reference volt-
age dependent upon which operational state is selected.
No Connect. May not be used as a tie point.
Ring Trip Sense. Sense input for the ring trip detector.
Ring Lead Ringing Access Switch. Ringing relay connects this pin to pin RRING. Con-
nect this pin to pin PR through a 400
Ringing Access. Input to solid-state ringing access switch. Connect to ringing generator.
Protected Ring. The output of the ring driver amplifier and input to loop sensing con-
nected through solid-state break switch. Connect to subscriber loop through overvoltage/
current protection.
Protected Tip. The output of the tip driver amplifier and input to loop sensing connected
through solid-state break switch. Connect to subscriber loop through overvoltage/current
protection.
Tip Ringing Return. Ring relay connects this pin to PT. Connect to ringing supply return.
Loop Status. The output of the loop status detector (loop start detector wired-OR with
ring trip detector). This loop status supervision output is not controlled by the data latch.
Data Control Input. See Table 2, Primary Control States and Table 3, Secondary Control
States for details.
Data Control Input. See Table 2, Primary Control States and Table 3, Secondary Control
States for details.
Data Control Input. See Table 2, Primary Control States and Table 3, Secondary Control
States for details.
Data Control Input. See Table 2, Primary Control States and Table 3, Secondary Control
States for details.
Reset. A logic low will override the B[0:3] and LATCH inputs and reset the state of the
SLIC to the disconnect state and the switch to the all-off state.
Latch Control Input. Edge-level sensitive control for data latches.
5 V Digital Power Supply. 5 V supply for digital circuitry.
