| 8.10.4 | The consequences of trying to install an analog modem into a digital jack
The technologies of an analog and a digital jack are very different and are not compliant. Analog modems use a standard phone line to gain remote access; where as, a digital jack is reserved to be used with an ISDN line or PBX switch. A NIC or a transceiver can burn out if it is exposed to the voltages of an analog phone line. Likewise, an analog modem can be damaged if it is plugged into a digital jack.
