Line groups

Your 984 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).
