Pin Description
Pin #
Name
Description
1
TIP
Tip Lead.
Connects to the Tip lead of a telephone line usually via an external protection
circuit.
2
RING
Ring Lead.
Connects to the Ring lead of a telephone line usually via an external protection
circuit.
3
XLA
Loop Relay Contact A.
Connects to XLB through relay contacts (K1A) when the relay is
energized.
4
XLB
Loop Relay Contact B.
Connects to XLA through relay contacts (K1A) when the relay is
energized.
5
XLC
Loop Relay Contact C.
Connects to XLD through relay contacts (K1B) when the relay is
energized.
6
XLD
Loop Relay Contact D.
Connects to XLC through relay contacts (K1B) when the relay is
energized.
7
IC
Internal Connection.
No connection should be made to this pin.
8
GRD
Ground Ring Lead Relay Drive (Output).
Connects to the Ground Ring Lead Relay coil
(K3) and is controlled by GRC.
9
IC
Internal Connection.
No connection should be made to this pin.
10
IC
Internal Connection.
No connection should be made to this pin.
11
RGND
Relay Ground.
Return path for relay supply voltage.
12
VRLY
Relay Positive Supply Voltage.
Normally +5V. Connects to all relay coils and the relay
supply voltage.
13
LRD
Loop Relay Drive (Output).
Connects to the Loop Relay coil (K1) and is controlled by
LRC.
14
BRD
Bias Relay Drive (Output).
Connects to the Bias Relay coil (K2) and is controlled by BRC.
15
LRC
Loop Relay Control (Input).
A logic 1 activates LRD. The Loop Relay (K1) is used for
placing the Line Termination across Tip and Ring.
