All, I have a customer with a 1890ect1/csc-50 Circa Surge Protection box in their DMARC. I have not seen one of these, and Im curious if anyone here has seen this and knows wht the pinout connections are like. Im trying to figure out how to connect some cat5 to this thing, so that I dont have to run more cable through this conduit between the buildings. Anyone seen this and know how the pins connect? Id appreciate it.
My bad! I haven't used an R66 style for awhile :) The Left Hand Block is actually the "In" cable (the Tie from either the CO or between buildings) and then the circuit runs through the Carbon protection modules to the "Out" cable (the Tie to the Rack or internal Building Cross-Connect) which is terminated on the Right Hand block.
The first 25 pair termination starts on the upper Left (Pair 1) and continues down the Left-Hand side to Pair 25. The second 25 pair starts on the upper Right (Pair 26) and continues down the Right-hand side to Pair 50.
Hope this helps my friend!
