Backbone Cabling

Consists of the cables or wireless links that provide interconnection between the entrance facility and MDF, and betweem the MDF and IDFs. (often composed of fiber-optic cables)

SOW (statement of work)

Documents in detail the work that must be completed for a particular project, and includes specifics such as tasks, deliverables, standards, payment schedule, and work timeline.

MOU (memorandum of understanding)

Documents the intentions of two or more parties to enter into a binding agreement, or contract, and is sometimes used between an informal handshake and the legally binding signatures on contacts.
