Hey all (again)
I got my Meridian 1 yesterday, and the seller forgot to include the power supply. Now I have to wait till Wednesday to use my system
That is besides the point, I got a Universal Trunk Card with it, and need to know the RJ-21 pinout for that (if I am using analog CO lines). I am almost 95% colourblind now, so a pin to wire chart would really help, showing what trunk number corresponds to what pairs (including tip/ring)
I really appreciate it!
 

The NT8D14 typically uses an Amphenol 50-pin connector. Each port corresponds to a pair of pins (one for Tip, one for Ring).

The odd-numbered pairs are used for the analog CO lines.
