Allow 3 pair per station on your count down the punch block for the 25 pair Amp. cable.
Digital sets actually only require 1 pair, the 2nd pair of each port.
the 1st pair is for SLT operation, XDP or if your using analog sets. It is a good practice to wire 2 pair to all your jacks. the 3rd pair on the blck is skipped.
Do as I mentioned above and I think you will be OK.
To check SLT operation you simply use an SLT or butt set.
