Understanding BSP's and operational theory

[Babybearjs]

I'm trying to wire in 2 208A KTU's to my system right now and am finding conflicting info concerning the BSP (518-114-110) and the 1955 information on the Interconnections for the 207, 208, and 212. in the practice it shows Battery "B" on terminals 39 and 40. but on the 1955 manual its showing Battery "C".... and... in the practice, it shows terminal 17 on the 208 connects to terminals 22,23, and 24.... I put a jumper between 17 and 22 and got my A-Lead connection. I thought these connections were already wired internally. I'm having to wire this KTU in a pair at a time, and when I tested the system, the units worked, but I don't know how the system is suppose to behave. when a extention is dialed, is the lamp suppose to wink, or glow with the signalling time and then go off.  is the lamp suppose to light up when the phone is picked up on that circuit? none of the documentation explains the operational theory of the 208 KTU
