When the subscriber hangs-up, check the intermittent tone. If cycle tone is detected, the collector of Q201 goes to a low logic. 9.3.4. Inializing Circuit 9.3.4.1. Function This circuit is used for to initialize the microcomputer when it incorporates batteries. 9.3.4.2.
9.4. Caller ID Detect Circuit 9.4.1. 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.

10.4. EEP ROM (IC802) 1. SCL SCL terminal is input terminal of Serial Clock to control transmit and receipt between Master and Slave. 2. SDA SDA terminal is input terminal, to forward the address and the mutual data between Master Device and Slave Device the mutual. This terminal needs the pull-up resistance external because output circuit of SDA uses Open Drain.
