Plug one end of the second telephone line cord for your TAD into the L2 jack of the 
two-line TAD. Plug the other end into the EXT. jack on the back of the machine. 

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 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, 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 Easy Receive, page 5-4.)

 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.

Troubleshooting and Routine Maintenance, Chapter 13.

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.
