Multi-Line Connections (Pbx); If You Are Installing The Fax/Mfc To Work With A Pbx - Brother FAX-645 Owner's Manual

Multi-Line Connections (PBX)

Most offices use a central telephone system. While it is often relatively simple to
connect the FAX/MFC 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 ONLY 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. (See Fax Detect (set ON by default), page 5-4.)
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 Answer Mode be set to MANUAL. All incoming calls should initially be
regarded as telephone calls.
3
The unit may be used with either pulse or tone dialing telephone service.
