Situation 2: You connected the HP LaserJet 3100
product to a jack for a phone line that receives both
fax and voice calls (a shared line).
Connect all other devices you have to the same jack as the HP
LaserJet 3100 product. See “Connecting other devices” later in this
chapter.
Note If you have another jack for this phone line, you can connect some of
the devices to it. However, if you have an answering machine or
computer with voicemail, connect it to the same jack as the HP LaserJet
3100 product.
Connecting other devices (optional)
How you connect the devices you have depends on whether the
devices have British Telecom sockets on the back. Phones or
combination telephone answering machines do not have this socket
and do not need one. However, check your other equipment: Most
answering machines and some modems have a British Telecom
socket. Many modems and computers with internal modems have an
RJ11 (American-style) socket.
If all the devices you are connecting have a British Telecom “Tel”
socket on the back, or if you are only connecting one device, use “To
connect devices with British Telecom sockets.” If you are connecting
at least two devices and one or more of them does not have a British
Telecom socket, use “To connect devices with British Telecom or
RJ11 sockets.”
