    摘要: In a signal detection circuit for an optical disk, a comparator converts an analog HF signal into a digital HF signal by using a slice level. A dropout detection circuit detects a dropout of the digital HF signal. A charge-pump circuit feeds back a slice-level control voltage to the comparator based on a result of the detection by the dropout detection circuit. A voltage follower holds and outputs a voltage stored in the capacitor. A switch is turned OFF when a dropout signal has been detected, and outputs to the voltage follower the voltage that has been stored in the capacitor during an ON state of the switch. A second switch is turned ON when a dropout signal has been detected, and applies an output of the voltage follower to the comparator.

    摘要: A VoIP gateway apparatus is used to provide an IP centrex service to accommodated devices. The VoIP gateway apparatus (1) assigns, to a call originated from an accommodated device (PBX 2), a telephone number for which the number of simultaneous call connections has not reached a simultaneous connection tolerance number, and sends the call to an IP centrex network (5) with the assigned telephone number used as a calling number. The VoIP gateway apparatus (1) includes a number-of-calls management part (105) and a SIP processing part (104). The number-of-calls management part (105) manages the number of the current simultaneous call connections for each of the telephone numbers as assigned to the apparatus. When a call is received from an accommodated device, a SIP processing part (104) selects, among the telephone numbers as assigned to the apparatus, a telephone number, for which the number of the current simultaneous call connections as managed by the number-of-calls management part (105) is smaller than the predetermined simultaneous connection tolerance number, and then transmits, to the IP centrex network (5), a SIP packet of a call control message to which the selected telephone number has been added as the calling number.
