Description
External Ring Trip Sensing Input.
Used to sense ring-trip condition when using centralized ring
generator. Connect to low side of ring sense resistor.
Test Relay Driver Output.
Drives test relays for connecting loop test equipment.
Ring Relay Driver Output.
Connects an external centralized ring generator to the subscriber
loop.
General Purpose Output Driver.
Used as a relay driver or as a second battery select pin when
using a third battery supply.
Battery Voltage Select Pin.
Switches between high and low external battery supplies.
Receive PCM Data.
Input data from PCM/GCI bus.
Transmit PCM Data.
Output data to PCM/GCI bus.
PCM Bus Clock.
Clock input for PCM/GCI bus timing.
Reset.
Active low. Hardware reset used to place all control registers in
known state. An internal pulldown resistor asserts this pin low
when not driven externally.
Frame Sync.
8 kHz frame synchronization signal for PCM/GCI bus. May be
short or long pulse format.
Interrupt.
Maskable interrupt output. Open drain output for wire-ORed
operation.
Serial Port Bit Clock Input.
Controls serial data on SDO and latches data on SDI.
Serial Port Data Out.
Serial port control data output.
Serial Port Data In.
Serial port control data input.
Serial Data Daisy Chain.
Enables multiple devices to use a single CS for serial port con-
trol. Connect SDITHRU pin from master device to SDI pin of
slave device. An internal pullup resistor holds this pin high during
idle periods.
