Microwave is a kind of leased line that uses a radio link rather than copper or fibre. Generally it requires a line of sight from the network location to an antenna dish mounted on or near your premises.
An Ethernet leased line can be connected to existing office-based Ethernet networks without additional protocol translation equipment. It ‘presents’ an Ethernet interface to the user.
A leased line is a copper or fibre connection providing a data service with a Service Level Agreement (for example, this may cover. download speeds, repair times and so on). Depending upon the type of service ordered the sockets and connectors, and their electrical characteristics, might differ from the usual Ethernet components that you may be familiar with.
Wireless links can be used instead of copper or optical fibre links to connect users from a wireless base station. Usually the base station is mounted on a mast or building at your premises. The connection’s performance is designed to be more stable and predictable than mobile because user equipment is in a fixed location. Often FWA uses mobile technologies adapted for fixed operations.
The original Cable TV networks used fibre optic links from the network to street side distribution points and coaxial copper lines to users’ premises. Coaxial copper lines have a higher capacity over longer distances than traditional ‘twisted pair’ copper telephone lines and this TV technology has been adapted to provide data communications at up to 120Mbit/s download speeds and 12Mbit/s upload speeds.
Where a supplier usually offers FTTC to customers as a standard product rather than FTTP (because of the high deployment costs), or if FTTC would not provide a sufficiently fast service to meet an individual customer’s needs, then some network operators would offer FTTP for an additional charge by offering what suppliers call an ‘on-demand’ product. Charges are often considerable and are payable upfront.
Where an optical fibre runs all of the way from the provider’s network to your premises. Very high download and upload speed (e.g. 10 Gigabytes per second and above) are possible with some types of active fibre systems. However, lower cost passive optical networks (PON), also classified as FTTP, are often used by suppliers and typically offer asymmetric speeds of up to 330Mbit/s download speed and 30Mbit/s upload speed.
There is no standard definition of Business Grade, but characteristics of a Business Grade line will be that it is oftensymmetric, always uncontended and will have a robust service level agreement from your supplier. Technologies above that would deliver a Business Grade service would be: Leased line, Leased line – Ethernet, Microwave, Ethernet First Mile (EFM) delivered on an uncontended/dedicated basis. Typically, Business Grade solutions will cost more, reflecting the higher quality and reliability of the service offered. The minimum speed you need to contract with your supplier for to use a Connection Voucher is 20Mbit/s upload or download. Remember that if you already have a Business Grade connection and wish to use a voucher to upgrade your service, your new connection must offer you at leastdouble the speed – that is from 10 to 20 Mbit/s or from 20 to 40, and so on if you choose one of these products.
The ‘next generation’ referred to is the industry-wide upgrade in technology from current ‘old’ methods that are used to deliver slower broadband speeds. In the list above, the NGA technologies are : Fibre to the premise, Fibre to the cabinet, Fibre on demand, Cable (DOCSIS 3.0), some newer types of Fixed Wireless Access, and Ethernet First Mile (EFM) delivered on a contended basis (that is, not a dedicated/uncontended line that only you use). Typically, NGA solutions will be lower cost than Business Grade and are likely to be both contended and asymmetric. The minimum speed you need to contract with your supplier for to use a Connection Voucher is 30Mbit/s either upload or download if you choose one of these products. If you already have an NGA connection at or above 30Mbit/s you should contact your city for requirements for the minimum speed that would be eligible for a Connection Voucher.

Is short for ‘Wide Area Network’. This is a type of communications network that uses devices such as telephone lines, satellite dishes or radio waves to span a larger geographic area that cannot be covered by LAN.
Is short for ‘Voice over Internet Protocol’. This implies the ability to make voice calls over the internet. In a mobile phone it would mean the ability to make a call using Wi-Fi, EDGE or any other internet service the handset permits.
Allows users to protect their voicemail, and lets the user pick up their messages from any touch-tone phone.
Is short for ‘Very high bit-rate Digital Line Subscriber’. VDSL is essentially an upgrade on ADSL which offers higher bandwidth and faster upload/download speeds.This identifies that voice communications use a very small amount of wire capabilities, and use the rest of the capability to provide improved data services.

Is short for ‘Near Field Communications’. This is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity. Present and anticipated applications include contactless transactions; data exchanged, and simplified setup of more complex communications such as Wi-Fi. Communications is also possible between an NFC device and an unpowered NFC chip called a ‘tag’.

is short for ‘Fibre To The Cabinet’. This is a new type of broadband that uses fibre optic cables to increase the speed of the customer’s broadband connection. This involves running fibre optic cables from the telephone exchange or distribution point to the street cabinets, which then connect to a standard copper phone line to provide the customer a faster broadband connection

Centrex (Central Office Exchange Service) is a service provided by the local company (usually BT) and allows companies access to powerful state of the art telephone facilities so that they do not need to purchase their own
Call Detail Records – An alphanumerical file containing the details of a call passed over the network. Typically including the CLI, number called, duration of call, time of call and where appropriate the cost of the call. These files are received from the carrier in bulk and processed by the billing platform.
Bandwidth describes how much data you can send through an internet connection and is usually measured in bits per second. Generally, increased bandwidth equals faster internet connections

Asymmetrical Digital Subscriber Line – a method for moving data over regular phone lines. An ADSL circuit is much faster than a regular phone connection and the wires coming into the premises are the same (copper) wires used for regular phone service. An ADSL circuit must be configured to connect two specific locations, similar to a leased line
Integrated Service Digital Network. This is essentially a digital network that will provide seamless communication of voice and data. The ISDN information is transferred in a digital form, which provides superior sound quality to the analague service.
O2 offer two ISDN products: ISDN2 and ISDN 30. The former provides two channels over the same wire at 64kbs. Then ISDN 30 provides a max of 30 channels and is an economic option if a company has more than 8 telephone lines.
