    10.3.1. Speakerphone Circuit 10.3.1.1. Function The circuit controls the automatic switching of the transmitted and received signals, to and from the telephone line, when the unit is used in the hands -free mode. 10.3.1.2. Circuit Operation The speakerphone can only provide a one-way communication path. In other words, it can either transmit an outgoing signal or receive an incoming signal at a given time, but cannot do both simultaneously.
  • Page 28 The attenuator control detects the setting of the volume control through Pin 24 of IC601 to automatically adjust for changing ambient conditions. 10.3.2. Telephone Line Interface 10.3.2.1. Circuit operation - On hook Q101 is open, Q101 is connected as to cut DC loop current and cut the voice signal.

    10.4. Caller ID Detect Circuit 10.4.1. Function (FSK signal) The caller ID is a changeable ID which the user of a telephone circuit obtains by entering a contract with the telephone company to utilize a caller ID service. For this reason, the operation of this circuit assumes that a caller ID service contract has been entered for the circuit being used.

    Description Name XDC Transmit detector output. A resistor and capacitor at this pin hold the system in the transmit mode during pauses between words or phrases. When the XDC pin voltage decays to ground, the attenuators switch from the transmit mode to the idle mode. The internal resistor at nominally 2.6 kohms.
