It's riddled with mistakes. SNET was never part of AT&T. GTE and Contel merged, keeping the GTE name, so GTE should be next to Contel. BOCs should be before the 7 RBOCs as part of AT&T. Many missing like NY Tel and NE Tel which became the NYNEX RBOC. MCI line should start with MCI. There are others, and arguably the Sprint/United connection needs to be with GTE. Nice idea, but I hope nobody uses this for serious information.
