Switchable Data Port
If you want to connect another device (such as a modem or fax machine)
to the wall jack,you can use the jack on the phone labeled DATA. You can
set the data port to use Line 1 or 2. Set the DATA SELECTswitch
located on the back of the phone to L1 or L2. A call picked up at another
extension on the line used by the data port may interrupt a fax,modem or
message transmission.
