S LIVM gouenbeg O Spuodas pun NO 1 M0d Printer functions and operation 99 inter timing diagram Pr Figure 20 EN LIU fax functions and operation PSTN operation The public switched telephone network PSTN operates by having a central office CO that generates a constant voltage on the TIP and RING wires 48 V usually When a device goes on hook it does so by connecting impedance such as 600 ohms for the US across TIP and RING allowing a line current to flow The CO can detect this current and it can send things like dial tones The product generates more signaling tones such as dialing digits to tell the CO how to connect the call The product also is able to detect tones like a busy tone from the CO to tell it how to behave When the call is finally connected the CO behaves as if it were a piece of wire connecting the sender and receiver This is the period during which all of the fax signaling and data transfer occurs When a call completes the circuit goes open again and line current ceases to flow removing the CO connection from both sender and receiver All of this is done with a two wire arrangement The two wires are called TIP and RING on all phone systems and on most phone systems they appear on pins 3 and 4 of the RJ 11 modular jack the one on the LIU for HP LaserJet 3330mfp These two wires do not have to be polarized as it is expected that all equipment works with either TIP or RING on pi
