Notes:
The Exchange name for this central office was CEntral. This was home to one of the largest 1A ESS switches in the world. The building to the left is an office building 405 N. Broadway and although it is connected to the Central building on the right side of the picture it is not part of the CO. These buildings are only 2 blocks away from where the Alfred Murrah building was before McVeigh destroyed it.Also serves on NXX code for the Norman ratecenter.
The AT&T Long Lines tandem (4ESS) is co-located with the local central office.
