Positive

Analog

Input

These are the analog inputs from the DAA.

AVDD

Analog Power

EE_DATA 18

Input/

Output

I2C EEPROM Data.

EE_CLK

Output

I2C EEPROM Clock.

MUTE

Speaker Mute

Control

Output

Controls speaker muting.

RDET/

LCS

Ring Detect

Input Line

Current Sense

Input

Signals the presence of a ring signal on the

line.The LCS_CHK input is used to detect when

a parallel phone is off-hook before dialing or

when a parallel phone has been picked up while

connected. In either case when LCS goes Low,

the connection attempt is dropped with a NO

CARRIER message.

VDD

Digital Power

Output

DGND

Digital Ground

LCS_CHK 24

Line Current

Sense

Output

This signal is used to enable the Line Current

Sense circuits in the DAA when checking for

parallel phone off-hook condition prior to taking

the phone line off-hook.

CID

Caller ID Relay Output

This signal is used to turn on the Caller ID relay

in the DAA.

SHTREL

Pulse Dial

Shunt Relay

Output

SHTREL works in conjunction with pulse dial

make/break. It offers extra-low resistance

across the tip and ring. When all relays are

closed, SHRTEL provides 100 Ohms (Low)

instead of 600 Ohms.

Off-Hook Relay

Output

This signal is used to turn on the off-hook relay

in the DAA.

DGND

Digital Ground
