Pin Description

PIN	Name	Description
1	RING	Connects to the subscriber line Ring.
2	TIP	Connects to the subscriber line Tip.
3	CATHODE	For power cross protection connect to protection device cathode.
4	ANODE	For power cross protection connect to protection device anode.
5	DMA	A resistor is connected between this pin and DMa to adjust the d.c. characteristics of the termination.
6	DMB	A resistor is connected between this pin and DMb to adjust the d.c. characteristics of the termination.
7	GATE	For power cross protection connect to protection device gate.
8	LC	A logic 1 Indicates that loop current is flowing.
9	Vin	Audio In.
10	Vout	Audio Out.
11	LSC	Loop switch control. Applying a logic 1 closes the integral loop switch.
12	GND	Analog ground. Normally connected to system ground.
13	VCC	Positive supply. Must be connected to +5V or +3.3V.
14	F/R	Forward/reverse. A logic 1 indicates that the Tip and Ring polarities are reversed. i.e. Tip is negative with respect to Ring. NOTE: When no line voltage is present the logic state is indeterminate.
15	ZB	Balance network. The network balance matching components are connected between this pin, VIN and GND.
16	ZT2	2 Wire matching network 2. The 2 wire impedance matching network is connected between this pin and ZT1. The compensation impedance Zc is connected between this pin and ZB.
17	ZT1	2 Wire matching network 1. The 2 wire impedance matching network is connected between this pin and ZT2.
18	RS	A logic 0 indicates the presence of ringing voltage on the telephone line. Toggles at ringing frequency.

19 Vref Reference voltage output. Used with VTR to detect parallel phone. Normally left open circuit. Approx. +VCC/2

20 Vtr Tip/Ring voltage. Indicates the voltage between Tip/Ring. Divided by 220 and relative to Vref.
