Prog. Transmit Gain. Left open transmit gain = 0.0 dB, connected to AGND transmit gain = -6.02 dB.  
Ring Relay driver output. The relay coil may be connected to maximum +14V.  
Connection for High Pass filter capacitor, CHP. Other end of CHP connects to TIPX.  
No internal Connection  
NC  
RINGX  
The TIPX and RINGX pins connect to the tip and ring leads of the two-wire interface via overvoltage  
protection components and ring relay (and optional test relay).

BGND  
TIPX  
Battery Ground, should be tied together with AGND.  
The TIPX and RINGX pins connect to the tip and ring leads of the two-wire interface via overvoltage  
protection components and ring relay (and optional test relay).

No internal Connection  
Connection for Low Pass filter capacitor, CLP. Other end of CLP connects to VBAT.  
Input to the ring trip comparator. With DR more positive than DT the detector output, DET, is at logic level  
low, indicating off-hook condition. The external ring trip network connects to this input.  
14  
DR  
Input to the ring trip comparator. With DR more positive than DT the detector output, DET, is at logic  
level low, indicating off-hook condition. The external ring trip network connects to this input.
