You can keep two-line telephones on other wall outlets as always. There are two
ways to add a two-line telephone to the FAX/MFC's wall outlet. You can plug
the telephone line cord from the two-line telephone into the L1+L2 jack of the
triplex adapter. Or, you can plug the two-line telephone into the TEL jack of the
two-line TAD.

Multi-Line Connections (PBX)

Most offices use a central telephone system. While it is often relatively simple
to connect the machine to a key system or a PBX (Private Branch Exchange),
we suggest that you contact the company that installed your telephone system
and ask them to connect the FAX/MFC for you. It is advisable to have a separate
line for the FAX/MFC. You can then leave the FAX/MFC in FAX mode to
receive faxes any time of day or night.
If the FAX/MFC is to be connected to a multi-line system, ask your installer to
connect the unit to the last line on the system. This prevents the unit from being
activated each time a telephone call is received.
As with all fax units, this machine must be connected to a two wire system. If
your line has more than two wires, proper connection of the FAX/MFC cannot
be made.

If You Are Installing the FAX/MFC to Work with a PBX:

1
It is not guaranteed that the unit will operate correctly under all circumstances
with a PBX. Any cases of difficulty should be reported first to the company that
handles your PBX.
2
If all incoming calls will be answered by a switchboard operator, it is
recommended that the Receive Mode be set to MANUAL. All incoming calls
should initially be regarded as telephone calls.
3
(For Canada only) The FAX/MFC may be used with either pulse or tone dialing
telephone service.
