To assist you in reading this Annual Report on Form 10-K, we have provided definitions of some of these terms below. Bandwidth infrastructure—Offerings of fiber and lit fiber (i.e., fiber that has been activated, or “lit”, by provider-supplied components) provisioned over the fiber network, mobile infrastructure connected to (or capable of being connected to) the fiber network, and data center based colocation and interconnection offerings. Lit fiber-based bandwidth infrastructure offerings include Wavelength, Ethernet, IP and SONET; fiber-based offerings that are not lit are sold as dark fiber capacity. Data center-based bandwidth infrastructure offerings include colocation (space and power) as well as interconnection within facilities. Capacity—The information‑carrying ability of a lit fiber offering. Below is a list of some common units of capacity for various lit fiber offerings: · 1G, 2.5G, 10G, 40G and 100G—Data communication circuits capable of accommodating Wavelengths at 1G, 2.5G, 10G, 40G, and 100G, respectively. · 10Mb and 100Mb—Data communication circuits capable of accommodating Ethernet communications at 10 Mb and 100 Mb, respectively. Carrier—A provider of communications services that commonly include voice, data, and Internet services. Carrier hotel—A data center facility containing many carriers and other telecommunications service providers, all of which may be widely interconnected. These facilities generally have high‑capacity power service, backup batteries and generators, fuel storage, riser cable systems, large cooling capability, and advanced fire suppression systems. Cellular tower—An outdoor structure primarily used to attach and house antennae used by wireless carriers to aggregate and transmit mobile voice and data. CLEC—Competitive local exchange carrier; a local telecommunications provider licensed to compete with some or all of the offerings of the ILEC. Colocation—The housing of telecommunications equipment, other communications equipment, servers and storage components within the same location. Operators of these colocation facilities typically also make available interconnection offerings to their tenants, enabling the tenants to cross connect with other customers located within the same facility and/or with bandwidth infrastructure providers. Conduit—A pipe usually made of metal, ceramic, or plastic that protects underground fiber optic cables. Cybersecurity— Preventative techniques used to protect the integrity of networks, programs and data from attack, damage, or unauthorized access. Dark fiber—Fiber that has not yet been connected to telecommunications access components or optronics and, therefore, has not yet been activated or “lit” by the provider-supplied components. Data center—A facility used to house computer systems, backup storage components, routers, servers and other Internet and other telecommunications equipment. Data centers generally have environmental controls (air conditioning, fire suppression, etc.), redundant/backup power supplies, redundant data communications connections, and high security. DWDM—Dense Wavelength-division multiplexing. The term “dense” refers to the number of channels being multiplexed. A DWDM system typically has the capability to multiplex up to 40 Wavelength channels. Ethernet—The standard local area network (LAN) protocol. Ethernet was originally specified as a standard for connection of components that share a company or home network, as well as to a cable modem or DSL modem for Internet access. Due to its ubiquity in the LAN, Ethernet has become a popular communication protocol in metropolitan, regional and long haul networks as well. i Table of Contents Fiber or fiber optic cables—Thin filaments of glass through which light beams travel over long distances. Fiber miles—The number of route miles in a network multiplied by the number of fiber strands within each cable on that network. For example, if a ten‑mile network segment has a 144 count fiber installed, it would represent 10x144 or 1,440 fiber miles. Fiber‑to‑the‑Tower or FTT—The connection of cellular tower sites to the wider terrestrial network via fiber connections. G—Gigabits per second, a measure of telecommunications speed. One gigabit equals one billion bits of information. ILEC—Incumbent local exchange carrier; a traditional telecommunications provider that, prior to the Telecommunications Act of 1996, had the exclusive right and responsibility for providing telecommunications offerings in its local service area, and in connection therewith typically built or acquired access to key elements of bandwidth infrastructure. Interconnection—A connection between two customers who are located within a single data center or within a single colocation space using fiber and/or other means. IP—Internet protocol; the network protocol used in accommodating movement of data over the Internet. IRU and IRU contract—Indefeasible right of use. The exclusive, unrestricted, and indefeasible right to use one, a pair, or more strands of fiber of a fiber cable. IRU contracts are typically long‑term in nature (20 years) and may or may not contain restrictions on the use of the fiber by the lessee.
