Hand-free function operation
Hand-free function execution
When HFO is low, a rising edge triggers the HFI, en-
abling the Hand-free function (HFO becomes high).
Reset Hand-free function
When HFO is high, the Hand-free function is enabled
and can be reset by:
Off-hook
Applying a rising edge to HFI
Changing the HDO pin from low to high
Hand-free function table
Hold-line function operation
Hold-line function execution
When HDO is low, a falling edge triggers the HDI, en-
abling the Hold-line function (HDO becomes high).
The XMUTE remains low when HDO is high.
Reset Hold-line function
When HDO is high, the Hold-line function is enabled
and can be reset by:
Off-hook
Applying a falling edge to HDI
Changing the HFO pin from low to high
Hold-line function table
DOUT BCD code
When dialing, the corresponding 4-bit BCD codes are
serially presented on DOUT from MSB to LSB. The data
of DOUT is valid at the falling edge of the CLOCK pin.
The following table lists the BCD codes corresponding
to the keyboard input.
