The yellow/slate pair from the ringer should be connected to a B1 and R1 pair. The CA terminals should be looped together with a single piece of wire. Each CA terminal from top to bottom represents the ringing output from each line card in numerical order. Envision them being 'CA1' through 'CA4'. They are factory-wired to each of the R terminal rows. The B terminal rows are factory-wired to the RG terminal where you connected your ring generator.
