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 machine for y ou. It is advisable to have a separat e line
for the machine. You can t hen leave the Receive Mode set to Fax
Only to receive faxes any time of the day or night.
If the machine 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 bei ng activated each time a telephon e call is
received.

If you are installing the machine to work with a PBX

1
It is not guaranteed that the unit will operate properly under all
circumstances with a PBX. Any cases of difficulty should be
reported first to the comp any that handles your PBX.
2
If all incoming calls will be answered by a switchboard operator,
it is recommended that the Re ceive Mode be set to Manual. All
incoming calls should initially be regarded as telephone calls.
Custom features on your phone line
If you have Call Waiting/Caller ID with the MFC-3320CN, or Call
Waiting, Voice Mail, RingMaster, an answering service, an alarm
system or other custom feature on one phone line it may create a
problem with the operation of your machine. (See Custom featur es
on page 1-7 and Custom features on a single line. on page 14-9.)
