7
LGND
Battery Ground
. VBat return path. Connected to system’s energy dumping ground.
8
LCA
Current Limit Set (Input).
The current limit is set by connecting an external resistor to
ground. For 30mA default current, this pin is tied to GND.
9
VBat
Battery Voltage
. Typically -48Vdc is applied to this pin.
10
DCRI
DC Ringing Voltage Input
. A continuous 120Vdc is applied to this input.
11
RGND
Relay Driver Ground Connection.
12
VRLY
Relay Supply Voltage Connection
.
13
RD
Ring Drive (Output).
Connects to ring relay coil.
14
SEL1
Select 1 (Input).
Refer to Table 5
15
SEL2
Select 2 (Input).
Refer to Table 5.
16
ESI
External Signal Input.
12/16kHz meter pulse input.
17
ESE
External Signal Enable.
Applies the external signal to the line.
18
AGND
Analog Ground.
VDD and VEE return path.
19
NATT
Network Balance AT+T Node.
Connects to N1 for a network balance impedance of AT&T
compromise (350
+ 1k
// 210nF); the device’s input impedance must be set to 600
.
This node is active only when NS is at logic high. This node should be left open circuit when
not used.
