If you use a PBX or ISDN converter or terminal adapter, then follow these steps to connect the equipment: 1 Connect one end of the telephone cable that came with the printer to the LINE port on the back of the printer. 2 Connect the other end of the telephone cable to the port designated for fax and telephone use. Notes: • Make sure the terminal adapter is set to the correct switch type for your region. • Depending on the ISDN port assignment, you may have to connect to a specific port. • When using a PBX, make sure the call waiting tone is off. • When using a PBX system, dial the outside line prefix before dialing the fax number. • For more information on using the fax with a PBX system, see the documentation that came with your PBX system. Connecting to a Distinctive Ring Service There is a plug installed in the EXT port of the printer. This plug is necessary for the proper functioning of the printer. Note: Do not remove the plug. If you remove it, other telecommunications devices in your home (such as telephones or answering machines) may not work. A distinctive ring service may be available from your telephone service provider. This service allows you to have multiple phone numbers on one telephone line with each phone number having a different ring pattern. This may be useful for distinguishing between fax and voice calls. If you subscribe to a distinctive ring service, follow these steps to connect the equipment: 1 Connect one end of the telephone cable that came with the printer to bottom LINE jack on the back of the printer. 2 Connect the other end of the telephone cable to an active analog telephone wall jack.
