5
RING
Connects to the “Ring” lead of the telephone line
6
LOOP
Loop Length Indication
. The output on this pin is proportional to the loop length /
resistance, and is valid for off hook conditions only.
7
BGND
Battery Ground
. This pin is the return pin for the battery feed to the line and also for the
message voltage supply and the Ring Voltage supply. This pin should normally be
connected to AGND.
8
WU
Wake Up(Output)
. When in the power down mode this pin goes high to indicate the phone
has gone off hook. When this occurs the power down signal should be removed.
9
EGB
Earth Ground Button Detection (Output)
This output goes low when the ring lead or tip
lead is grounded.

IC
Internal Connection
11
VBAT
Battery Feed Supply
. This pin is the supply for the line feed. (Typically -48V).

IC
Internal Connection
13
PD
Power Down (Input)
Applying a logic 0 (Active low) will Power down the hybrid. This may
be used, but must be removed to allow a call to be made or to reduce power consumption.
14
AGND
Analog Ground
. This pin is the return pin for the positive and negative supplies and is
normally connected to BGND.
15
VDD
Positive Supply
. (Typically +5V).
16
VEE
Negative Supply
. (Typically -5V).
17
IC
Internal Connection
18
VR
Receive (Input).
The audio input signal is applied to this pin from the programmable
CODEC. This signal is internally a.c. coupled
