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 
as an SCS (Small Communications System).
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.

where the circuit pack is located (for example, 01, 02, ..., etc.); and pp is the 2-digit
