RJ11 One Male to Three Female Modular T-Adapter, L1/L2/L1+L2

RJ11 One Male to Three Female Modular T-Adapter, L1/L2/L1+L2

This modular T-adapter plugs into a standard two-line telephone jack and split the line, directing the first line to one jack (L1) and the second line to the other jack (L2). With a splitter, you will just have two single-line phones coming off the same jack. One of the phones will receive calls from line one (L1), and the other will receive calls from line two (L2). A combined line one plus line two (L1+L2) allows you to keep your two-line telephone connected.
