Using the Internal Modem
Connection procedures

❖ If a (working) telephone connected to the wall jack has an
REN (Ringer Equivalency Number) printed on its label, then
it is an analog phone. If the phone is working correctly, then
the wall jack itself is analog.
❖ Telephones in an office environment are commonly
connected to digital phone lines.
❖ Unfortunately, the wall jacks for both analog and digital
phone lines use the familiar RJ11 connector as shown below.
If you are not sure that an RJ11 jack terminates an analog
phone line, do not connect the modem to it.
