The two articles in bold below relate to buildings in AT&T's and Verizon's territories that were previously serviced, prior to their respective mega-mergers, by TCG (owned by AT&T) and MFS (owned by MCI) in their own service areas. These required divesting in order to preserve competitive conditions, where AT&T, up until now was serving the same buildings with TCG, and Verizon with MFS. Now those buildings will be dual served by Above and Level3 in lieu of TCG and MFS.

Digital ROADMs: Completing the promise of the optical network revolution By Geoff Bennett, Infinera
Due to their analog nature, ROADMs have significant limitations, including limited management capability, lack of subwavelength multiplexing, and the iunability to exploit the full benefits of a GMPLS control plane. However, a new class of ROADM, based on digital technology, is now emerging to address these limitations and deliver a range of additional benefits to the service provider.
