Transistor Emitter.
Connects to the emitter of Q3.
DC Termination.
Provides dc termination to the telephone network.
Receive Input.
Serves as the receive side input from the telephone network.
Internal Bias.
Provides a bias voltage to the device.
Isolation Capacitor 1B.
Connects to one side of isolation capacitor C1 and communicates with the system side.
Isolation Capacitor 2B.
Connects to one side of isolation capacitor C2 and communicates with the system side.
Voltage Regulator.
Connects to an external capacitor to provide bypassing for an internal power supply.
Ring 1.
Connects through a resistor to the RING lead of the telephone line. Provides the ring and
caller ID signals to the Si2457/34/15/04.
Ring 2.
Connects through a resistor to the TIP lead of the telephone line. Provides the ring and
caller ID signals to the Si2457/34/15/04.
Voltage Regulator 2.
Connects to an external capacitor to provide bypassing for an internal power supply.
SC Connection.
Enables external transistor network. Should be tied through a 0 Ω resistor to I
