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 MFC for you. It is advisable to have a separate line for
the MFC. You can then leave the MFC in FAX mode to receive faxes
any time of day or night.
If the 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 MFC cannot be made.

If you are installing the MFC to work with a PBX:

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.
If all incoming calls will be answered by a switchboard
operator, it is recommended that the Answer Mode be set to
MANUAL. All incoming calls should initially be regarded as
telephone calls.
The unit may be used with either pulse or tone dialing
telephone service.
