Switch to data CONNECT A PHONE HANDSET TO THE MODEM'S RJ11C LINE JACK If you have a telephone with a handset that has a cable with an RJ11C connector plugged into the phone set base unit, you can unplug the handset and plug it into the modem LINE Jack and then use the handset as both a microphone and a speaker. The two central wires in the LINE Jack are the signal wires to be connected to the phone company. If you connect the handset to this LINE Jack, normally the earphone in the handset will be connected to the modem's two-wire line terminals. You can hear the voice when the modem is in playback mode and you can speak to the earphone (remember "earphone") while recording. In recording mode, the earphone is used as a microphone. CAUTION: Never plug the handset into the modem's PHONE Jack because it will be connected to the phone line when modem is on-hook and it will be damaged by the phone line's DC voltage and current. CONNECT A TELEPHONE SET TO THE MODEM'S RJ11C LINE JACK A normal telephone set cannot be connected to the modem's LINE jack and used for recording and playback. A telephone set needs DC voltage and a current supply to work. This DC voltage is normally supplied through the phone line from the telephone company or PABX. A specially designed "Switch Box" can be used to interface the telephone set to the modem. On one side of the Switch Box it connects to the phone line and telephone set; on the other side it connects to the modem's LINE and PHONE jacks. In normal conditions, the modem's LINE and PHONE jacks connect to the phone line and telephone set through this Switch Box. When the switch on the Switch Box is pressed down, the telephone set is connected to the modem's LINE jack and the Switch Box provides a DC voltage to it. The other connections are cut off. The telephone set can then be used as a recording input or a playback output for the modem's voice function. If a facsimile is connected to the PHONE SET terminal of the Switch Box, it can be used as a scanner or printer for the computer connected to the modem. Chapter Sixteen - NETWORK MANAGEMENT CAPABILITY When there are many modems installed at different places forming a modem network, it is desirable to monitor and control all the modems and modem links from a central location. When there are hundreds of modems installed at one central location, it is also desirable to control and monitor all the modems from the desk of a computer workstation. We call this a Modem Network Management System (MNMS). In this chapter we briefly describe the ZyXEL MNMS capability. For detailed description, please refer to the rack's user manual and the NMS software ZyView's operation manual. ZyXEL MODEM NETWORK MANAGEMENT SYSTEM ZyXEL's MNMS is centered around its rack system.
