I/O TYPE Description
Output DTE Data Carrier Detect output signal. Indicates modem has detected carrier.
Input Ring detector input. This pin assumes that a half wave opto coupler is used in the
telephone line DAA circuit in the frequency detection algorithm.
Input DTE Ready To Send input signal. Used for hardware flow control.
Input DTE Data Terminal Ready input signal. Used to enable modem device
Intput Country Selection bit 0 (Internal pull up)
Input Country Selection bit 1 (Internal pull up)
Input Country Selection bit 2 (Internal pull up)
Input Country Selection bit 3 (Internal pull up)
Input Reset signal to the AMC2442A Controller. Active High.
Input DTE Transmit Data Pin. All data communication from the DTE connects via this pin.
Output DTE Receive Data Pin. All data communication to the DTE connects via this pin.
Input Receiver Clock Input from AFE. Used in PSK, QAM and synchronous data mode.
Input Transmitter Clock Input from AFE. Used in PSK, QAM and synchronous data mode.
I/O DO NOT CONNECT
Output DTE Clear To Send output signal. Used for hardware flow control.
Output Write signal to AFE. Goes active low whenever the SMC wishes to write to the AFE
Output Read signal to AFE. Goes active low whenever the SMC wishes to read from the AFE
Output Buffered Clock output signal. Also used as a crystal drive signal when required.
Input Clock input signal. The SMC requires an 11.0592MHz signal on this pin.
Power Controller Ground connection
Output Speaker Enable drive
I/O DO NOT CONNECT
I/O DO NOT CONNECT
Output DAA Line Seize relay control. Used if DPCO relay is used to share the telephone with a
standard telephone instrument.
Output DAA Bell Shunt control. Used during LD dialling to provide a low impedance loop.
Input Line-In-Use detection input.
Output Line-In-Use circuit drive pin.
Output DAA Hook switch control. Delayed from Seize to allow for a low cost opto coupler.
I/O DO NOT CONNECT
Output ALE signal to AFE. Goes active high to latch an address into the AFE
Power Auxiliary power supply pin.
I/O Multiplex Address / Data bus connections to AFE.
Power Main power supply pin.
