蔵電話機オフフツク検知回路。 In a facsimile network control device that can connect a high-resistance built-in telephone that has an output terminal for mailbox information and an external telephone that does not have mailbox information, there is a relay drive unit that operates a relay based on the mailbox information, and a It consists of a resistor that generates a potential difference due to the direct current that flows when the phone is off-hook, an external phone off-hook detection section that detects the potential difference, and a low resistance and relay contact that are connected in parallel. A built-in telephone off-hook detection circuit characterized in that off-hook detection resistors are connected in parallel with low resistance and another contact of the same relay constitutes an external I/O.
