HYB-LINE (Hybrid Line)
Hybrid Line is the user-friendly name for Hybrid Line, which was previously used
to denote the Multifunction Analog Telephone. The Hybrid Line set is also known

The TN762B Hybrid Line circuit pack supports eight of these multifunction analog
telephone sets, as shown in the following figure. The Hybrid Line sets use three
pairs of wires: an analog voice pair, a transmit/receive pair, and a power pair.
