Pedestals with louvered doors are almost exclusively used for CATV. This is because all of their gear is designed for outdoor (aerial use). Louvered doors aren't used for telco splices because of the potential for moisture.
Don't forget that this pedestal is double-sided, so it is possible that everything in there is completely accessible from the other side.
Then again if it is CATV, since when do they and the telcos get along, especially now that they are in competition with each other?
