Line groups
Your 974 telephone is noted for its line-sharing feature. The four-line CO key
indicators show the line status by displaying different colors and modes (on /
off / flashing). To have an accurate line status indication, all units which are
connected to the system MUST have their Line 1 jacks connected to the
same telephone line (i.e.TL1), Line 2 jacks connected to the same telephone
line (TL2), and Line 3 jacks connected accordingly to (TL3).
