In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access. DSL service can be delivered simultaneously with wired telephone service on the same telephone line. This is possible because DSL uses higher frequency bands for data. On the customer premises, a DSL filter on each non-DSL outlet blocks any high-frequency interference to enable simultaneous use of the voice and DSL services.

Disaster Recovery – involves the policies and procedures needed to enable recovery or continuation of vital technology infrastructure and systems following a natural or human induced disaster.

DOCSISan international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access over their existing hybrid fiber-coaxial infrastructure.

DSLAM – This stands for digital subscriber line access multiplexer. These are usually located at telephone company exchanges, and the further away your home is to one, the slower your broadband connection will be.

Duct Bank – are groups of conduits that are often buried and are designed to protect and consolidate cabling. In a duct bank, data cables are laid out within PVC conduits that are bundled together; these groupings of conduit are protected by concrete and metal casings.

DWDM – Dense Wave Division Multiplexing. This allows for a multiplication in capacity and bi-directional communications over a strand of fiber via waves.A DWDM system creates waves that have thin bands yielding 80 waves total for a given path. Compare with CWDM.


E


F

They are made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair. The fiber cable consists of a core, cladding, and a protective outer coating.

Fiber-to-the-home(FTTH) – also called “fiber to the premises” (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses to provide unprecedented high-speed Internet access.

Firewall – A security system designed to protect a network from external threats (hackers). A hardware and software combination usually makes the firewall that separates a Local Area Network (LAN) from a Wide Area Network (WAN) and prevents unauthorized access to the LAN through the use of electronic security mechanisms such as IP filtering and address remapping.

Fog Computing – is a paradigm that extends cloud computing and services to the edge of the network. Similar to cloud, fog provides data, compute, storage, and application services to end-users. The distinguishing fog characteristics are its proximity to end-users, its dense geographical distribution, and its support for mobility. Services are hosted at the network edge or even end devices such as set-top-boxes or access points. By doing so, fog reduces service latency, and improves QoS, resulting in superior user-experience. Fog computing supports emerging Internet of Everything (IoE) applications that demand real-time/predictable latency such as industrial automation, transportation, and networks of sensors and actuators.


G

G.fast –  is a digital subscriber line (DSL) standard for local loops shorter than 500 m, with performance targets between 150 Mbit/s and 1 Gbit/s, depending on loop length. High speeds are only achieved over very short loops

I

ILEC – (incumbent local exchange carrier) is a local telephone company which held the regional monopoly on landline service before the market was opened to competitive local exchange carriers. In much of the United States, these were originally Bell System companies, although various regional independents (including GTE) in the US held incumbent monopolies in their respective regions. BellSouth (AT&T) is an example of an ILEC.

Innerduct – Located within a conduit or sheath, innerduct seperates strands of fiber-optic cable from others. A sheath or conduit may be made up of multiple bundles of fiber, each enclosed with its own innerduct and sometimes owned by separate providers.

Interconnection – The linkage, by wire, radio, satellite, or other means of two or more existing telecommunications carriers or operators with one another for the purpose of allowing the subscribers of one carrier to reach the subscribers of other carriers.

Internet Exchange  –  is a location where the networks of Internet Service Providers (ISPs), telecommunications carriers, content providers, and webhosters meet to exchange IP traffic with one another. This exchanging of regional, national, and international IP traffic is generally known as peering in a cost-neutral situation.

Parties generally peer at an Internet Exchange in order to decrease network costs, improve network performance, and make their network more redundant. Improving network performance is achieved by accessing many networks directly at the exchange which otherwise would have taken a longer route through other providers. Redundancy is created by having many routes at the exchange through which traffic can be sent.

Internet of Things – (IoT) is a scenario in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. Experts estimate that the IoT will consist of almost 50 billion objects by 2020.

Internet Service Provider – (ISP)  is an organization that provides services for accessing, using, or participating in the Internet. Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned. ISPs can be grouped into tiers reflecting their connection to the Internet backbone. A tier 1 network is one that can reach every other network on the Internet without purchasing IP transit or paying settlements, AT&T or Level 3 Communications are examples of tier 1 networks. A tier 2 network peers with some networks, but still purchases IP transit or pays settlements to reach at least some portion of the Internet, Florida LambdaRail is an example of a tier 2. A tier 3 network is one that solely purchases transit from other networks to reach the Internet, the Escambia County network is an example of a tier 3 network.

IP Address – is an identifier for a computer, device or object on the Internet. The original version is known as IPv4 and provided about 4.2 billion unique addresses. The current version is IPv6 which will provide 340,282,366,920,938,000,000,000,000,000,000,000,000 unique addresses.

IPTV – This stands for internet protocol television. It refers to the technology which delivers television through an internet connection. A set-top box is required to access this technology, allowing you to watch television programs on demand.

IRU – (Indefeasible Right of Use) means the exclusive, unrestricted, and indefeasible right to use the relevant capacity (including equipment, fibers or capacity) for any legal purpose.  An IRU gives the purchaser the right to use some capacity on a telecommunications cable system, including the right to lease that capacity to someone else. However, with that right comes an obligation to pay a proportion of the operating cost and a similar proportion of the costs of maintaining the cable including any costs incurred repairing the cable after mishaps. For information from an accounting perspective see this Ernest & Young paper “IRU arrangements: A purchaser’s guide to identifying and classifying leases

A local option sales tax is often used as a means of raising funds for specific local or area projects, such as improving area streets and roads, or refurbishing a community’s downtown area.

LTE – (Long Term Evolution) is a 4G wireless broadband technology developed by the Third Generation Partnership Project (3GPP), an industry trade group and represents the next step (4G) in a progression from GSM (a 2G standard) to UMTS (the 3G technologies based upon GSM). LTE provides significantly increased peak data rates, with the potential for 100 Mbps downstream and 30 Mbps upstream, reduced latency, scalable bandwidth capacity, and backwards compatibility with existing GSM and UMTS technology. Future developments to could yield peak throughput on the order of 300 Mbps.


M

Make Ready – Everything that needs to be done to make a facility ready to receive the fiber-optic cable or similar preparations necessary to build fiber along a given route. This could include permitting, masonry, electrical work, moving existing cabling to make room for new attachments. A common example is moving existing communications cabling on power poles to make room for additional cabling.

Managed Services – is a business model where a communications service provider offers day-to-day operation and management of the network between customer locations under an agreed service level agreement. Typically, the customer pays a monthly fee to the service provider and receives a pre-determined network bandwidth that can vary on a per location basis.

Meet-me-room – is a place within a colocation center (or carrier hotel) where telecommunications companies can physically connect to one another and exchange data without incurring local loop (last mile) fees from the local telephone company.

Multicast – A process of transmitting data from one source to many destinations.


N

NAP – Network Access Points. Commonly referred to as Internet Exchange Points (IXPs) and are places in which large network providers converge for the direct exchange of traffic. Typically, an ISP or network provider will access Tier 1 global providers and their networks via a NAP. NAPs also serve as meet-me points for like networks. Also known as Carrier Hotels or ISP shopping malls.

Node – A node is any device connected to a computer network and can be computers, cell phones, tablets, or various other network appliances. On an IP network it is any device with an IP address.

NTIA – National Telecommunications and Information Administration which is part of the Department of Commerce, is the Executive Branch agency that is principally responsible by law for advising the President on telecommunications and information policy issues.


O

Open Access Network (OAN) – a network architecture and business model that separates the physical access to the network from the delivery of services. In an OAN, the owner or manager of the network does not supply services for the network; these services must be supplied by separate retail service providers. There are two basic models, in the two layer model there is a network owner and operator, and multiple retail service providers that deliver services over the network. In the three layer model the physical layer is owned by one company, the operations and maintenance of the network and the provision of services is run by a second company, and the retail service providers provide the third layer.

OTT – (Over-the-Top) In broadcasting, OTT refers to delivery of audio, video, and other media over the Internet without the involvement of a multiple-system operator (cable company) in the control or distribution of the content. The Internet provider may be aware of the contents of the network traffic but is not responsible for, nor able to control, the viewing abilities, copyrights, and/or other redistribution of the content. This model contrasts with the purchasing or rental of video or audio content from an Internet service provider (ISP), such as pay television video on demand or an IPTV video service, like AT&T U-Verse. OTT in particular refers to content that arrives from a third party – such as Hulu or Netflix – and is delivered to an end-user device, leaving the ISP only the role of transporting IP packets.

Overlashing – a method of installing aerial fiber by lashing to an existing lashed fiber or copper cable instead of a dedicated messenger cable.


P

Passive Optical Networking (PON) – A passive optical network is a system that brings optical fiber cabling and signals all or most of the way to the end user. The passive simply describes the fact that optical transmission has no power requirements or active electronic parts once the signal is going through the network. A PON consists of an Optical Line Termination (OLT) at the service providers location and a number of Optical Network Units (ONUs) near end users. Typically, up to 32 ONUs can be connected to an OLT.

POP – Point of Presence. The point at which local Internet Service Providers connect to regional and national networks. Distance to the POP can influence service availability and pricing.

POTS – Plain old telephone service, an industry accepted acronym that defines the telephone lines connected to most residential users.

PSTN – Short for Public Switched Telephone Network, which refers to the international telephone system based on copper wires carrying analog voice data. This is in contrast to newer telephone networks base on digital technologies, such as ISDN and FDDI. Telephone service carried by the PSTN is often called plain old telephone service (POTS).

Public-Private Partnership (PPP or P3) – is a contractual arrangement between a public agency (federal, state or local) and a private sector entity. Through this agreement, the skills and assets of each sector (public and private) are shared in delivering a service or facility for the use of the general public. In addition to the sharing of resources, each party shares in the risks and rewards potential in the delivery of the service and/or facility.

V

VDSL2 – (Very-high-bit-rate digital subscriber line 2) is an access technology that exploits the existing infrastructure of copper wires that were originally deployed for traditional telephone service as a way of delivering very-high-speed internet access. The main high-speed link (e.g. a fiber optic connection) terminates at a hub near the customers’ location. The existing copper wire infrastructure is then used to carry the high speed connection for the short remaining distance to the customers. It can be deployed from central offices, from fiber-optic connected cabinets located near the customer premises, or within buildings. It has been defined in standard ITU-T G.993.2 finalized in 2005.

WDM – Wavelength-division multiplexing. A method of combining multiple signals on laser beams at various infrared wavelengths for transmission along fiber optic media.

Wide Area Network (WAN) – A large computer and voice network. Typically it is larger than a metropolitan area. The wide area network uses communications technologies to link its network segments, which can be one big network or linked local area networks (LANs). Computers connected to a wide area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites.

Wi Fi – is a wireless networking technology that allows computers and other devices to communicate over a wireless signal. It describes network components that are based on one of the 802.11 standards developed by the IEEE and adopted by the Wi-Fi Alliance.
