Preliminary Information
Figure 2 - Pin Connections
Pin Description
Pin #
Name
Description
1
TIP1
Tip Lead.
Connects to the “TIP” lead of subscriber line 1.
2
RING1
Ring Lead.
Connects to the “RING” lead of subscriber line 1.
3
V
BAT
Battery Voltage.
Typically -48V dc is applied to this pin. This should be connected to pin 38
of the hybrid on the PCB.
4
DCRI
DC Ringing Voltage Input.
A continuous 120V dc is applied to this input to achieve
90Vrms ringing. This should be connected to pin 37 of the hybrid.
5
GND
Ground.
This pin should be tied to pins 13, 28 & 36 on the PCB.
6
ESI1
External Signal Input (Input).
A continuous signal should be applied to this pin which will
be switched to “Tip” and “Ring” of subscriber 1.
7
ESE1
External Signal Enable (Input).
The external signal to the subscriber 1 is controlled by a
logic level applied to this pin.
8
VR1
Receive (Input).
4-Wire GND referenced audio input for subscriber 1.
9
SHK1
Off Hook Indication (Output).
A logic low output indicates when subscriber 1 equipment
has gone off hook.
10
LCS1
Loop Current Set 1
. Logic 1 gives I
Loop
= 40mA, Logic 0 gives I
Loop
= 25mA
Transmit (Output).
4-Wire, GND referenced audio output for subscriber 1.
11
VX1
12
VEE
Negative Supply Voltage.
-5Vdc. Connects to pin 29 of the hybrid on the PCB.
13
GND
Ground.
Return path for VDD, VEE, VBat & DCRI. This pin should be connected to pins 5,
28 & 36 of the hybrid on the PCB.
14
VDD
Positive Supply Voltage.
+5Vdc. Connect to pin 27 of the hybrid on the PCB.
15
LR1
Line Reversal.
A logic 1 applied to LR1 will reverse the “Tip” and “Ring” to subscriber 1.
This pin has an internal pull down.
16
RC1
Ringing Control (Input).
A logic level applied to this pin enables ringing to be applied
across Tip and Ring of subscriber 1.
