How do i wire a phone jusk up to use a 3rd and 4th line? - phone line wiring diagram

My office telephone has 4 lines, pin connected to the line 1 a.m.-2 p.m. with a 6-stroke and then 3 a.m. to 4 p.m., on the other 3 a.m. to 4 p.m., are not appropriate, however. How to wire? I saw a wiring diagram for a series of 6 pins 3 a.m. to 4 p.m. to see, but provide useful results. Help?
