7 chapter USING AN INTERNAL MODEM The information in this chapter applies to all computer models with internal modems. NOTE: The modem does not support the modem pass-through connection available on some optional docking bases. Connecting the Modem Cable IMPORTANT: The internal modem uses a universal DAA (Direct Access Arrangement) that supports multiple countries. However, in some regions, you may need to use an adapter to connect the modem to the telephone wall jack. If you are connecting the cable to a telephone jack that is not an RJ-11 jack, refer to "Using a Country-Specific Modem Adapter" later in this chapter. IMPORTANT: Wall jacks for digital PBX systems may resemble standard telephone jacks but are not compatible with analog devices such as modems. Be sure the modem cable is connected to a regular analog phone line. Plugging the modem into a digital line will result in no dial tone and is not recommended. The modem includes protective circuitry against the digital lines producing excess current. A warning buzz will sound briefly when excessive current is detected during a call attempt and the attempt is terminated with the phone line back on-hook. ! WARNING: To reduce the risk of electrical shock, always ensure that the modem line is disconnected from the telephone network when opening the equipment's enclosure. ! WARNING: To reduce the risk of electrical shock, fire, or damage to the equipment, do not plug a telephone cable into the Ethernet RJ-45 jack. Using an Internal Modem 7-1
