NOT QUITE AN ANSWER I don't know why, from a historical perspective. Possibly because it's the simplest way to arrange the keys using the tone dialing scheme. The individual keys' dialing tones are created by mixing two tones. There are three tones for the columns, and four for the rows. Each key makes a predefined combination tone.

How do you determine transfer function of a synchronous generator?
This is just one of the ways:Choose the variables couple in question defining the SISO form of the system. Write out the state space matrix commonly denoted as "A" of the synchronous machine. Calculate the eigenvalues of that matrix. Then calculate the residues of the matrix with respect to the selected SISO system (the chosen variables in question define the input matrix B and output matrix C). The eigenvalues are the zeros of the transfer function while the residues are the constants in the fractionally partitioned form of the transfer function.The matrices I was talking about define the linearised system in the form :dx/dt=Ax+Buy=CxFor a more thorough explanation seePower System Stability And Control By Prabha Kundur
Why prefer nominal pi circuit over nominal T circuit in transmission line modeling?
Nominal Pi is used for the transmission line modeling as it makes the Y matrix representation more accurately and in actual sense we get a conditioned matrix.
