Jargon Buster

Red Question Mark

A collection of useful Jargon definitions – some common and some not so common technological terms to help you understand the abbreviations that are often used in relation to all forms of communication – if there are any missing please let us know!

ADSL (Asymmetric Digital Subscriber Line)

ADSL is a basic broadband service used mainly for accessing the Internet, it allows data to be transferred over copper lines from the exchange to the premises. By adding a micro-filter the line can also be used for voice calls and the connection of analogue devices.

Analogue Lines

A conventional analogue telephone line delivered on copper wiring generally used for direct analogue telephones, fax machines, alarm lines, PDQ machines and other analogue devices. Standard ADSL services usually require an analogue line.

Auto Attendant

Auto Attendant is an automated call technology that answers external calls and provides the caller with options for choosing the department they wish to speak to.

Avaya

Avaya is an American multinational technology company specialising in business communication systems and is ranked at No. 101 on Forbes America’s Largest Private Companies.

 

BYOD (Bring Your Own Device)

Bring your own device (BYOD) refers to employees who bring their own technology ie. smart phones, laptops and tablets into work that can be connected to the internal network.

Cloud Services

Traditionally technical services were either hardware in the office or were installed on users local computers – cloud services are hosted on internet which enables companies to share data more effectively whilst centralising their network security. It can also cut costs by reducing the number of both computers and licences required.

Digital

This represents the way a computer reads information which is in a binary form consisting of 1 or 0. Although basic, this Digital method can represent huge amounts of data which can be also be stored and replayed on CDs and DVDs.

Domain

A group of computers specific to a local network that are accessed and administered by a common set of rules are described as being in a ‘Domain’

Domain Name

Every website has a unique identifying address called a domain name and is used to access the website from the address bar when added to the host domain and TLD.

Domain Name example: (www.)’digicomm360′(.com)

DR (Disaster Recovery)

Disaster Recovery (DR) is a set of rules and procedures designed to protect and recover the critical data infrastructure of a company and to restore it to working order thereby helping to maintain business continuity after an unforeseen disaster.

EFM (Ethernet in the First Mile) Data

Ethernet in the First Mile (EFM) delivers flexible data connectivity over a choice of two copper pairs (up to 10Mbps) or four pairs (up to 20Mbps), with a minimum symmetrical speed guarantee.

Firewall

A Firewall is usually a piece of hardware (ie. a router) that is connected to an internet socket and acts as a barrier to prevent external threats gaining access to the local network (LAN). It can be configured to allow as much or as little traffic inbound and outbound as required and, for example, could block all IP addresses flagged on a blacklist or be further configured to accept only trusted IP addresses ie. those on a whitelist.

Fixed Cellular Terminals (FCTs)

Also known as GSM (Global System for Mobile) Gateways or Premicells, FCT’s route Landline to Mobile calls via the GSM Network to enable users to benefit from substantially reduced calling rates.

FQDN (Fully Qualified Domain Name)

A fully qualified domain name (FQDN) contains a hostname, a domain name and a TLD in the following format:

‘hostname’.’domainname’.’tld’ – www.digicomm360.com

FTTC – Fibre to the Cabinet

 

FTTC (Fibre to the Cabinet) is a data communications technology that enables superfast data transmission via a fibre connection from the local telephone exchange directly to the distribution point outside your premises (the cabinet), where a copper cable is then run from the distribution point (DP) to your premises thus greatly reducing the overall copper cable distance and therefore increasing connection and data speeds whilst also reducing the possibility of copper degradation.

FTTP – Fibre To The Premises

FTTP (Fibre to the Premises) is a data communications technology that enables superfast data transmission via a fibre connection from the local telephone exchange directly to the your premises.

IOT (Internet of Things)

Internet of Things (IOT) refers to any kind of device that can be internet enabled. Historically this has been just devices such as PCs, tablets, smartphones etc. but the scope of the technology has recently widened to include home appliances, cars, wearable electronics

IP (Internet Protocol)

Simply put, Internet Protocol provides a standard set of rules that govern the sending and receiving of data over the internet. In many cases this is used synonymously when referring to an IP Address.

ISDN (Integrated Services Digital Network)

Integrated Services for Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the telephone network. It comes in two types:

BRI (Basic Rate Interface) is delivered over a pair of standard telephone copper wires called a circuit (2 channels) which will carry two simultaneous calls or

PRI (Primary Rate Interface) which starts with a minimum of  8 channels and up to a maximum of 30 and is usually connected to a PBX.

LAN (Local Area Network)

A local area network (LAN) allows the relatively fast transmission of data within a local network of limited distance.

PC

A PC (personal computer) is a programmable electronic device intended to be operated by a single individual and is used in conjunction with devices such as a keyboard and mouse.

QOS (Quality of Service)

The goal of QOS (Quality of Service) is to provide  sufficient bandwidth, control latency and jitter, and reduce data loss for critical delivery applications and services that require it, such as voice etc.

Router

So named because a router is designed to route data from a local area network (LAN) to another network connection and only allows authorised machines to connect to other computer systems. Certain types of routers also record the activity passing through it.

SDSL (Symmetric Digital Subscriber Line)

SDSL is a basic broadband service used mainly for accessing the Internet and allows data to be transferred over copper lines from the exchange to the premises. It differs from ADSL in that the upload speed is the same as the download speed (Symmetric).

Server

A server provides functionality for programs or devices called ‘Clients’ and allows the sharing of data or resources across multiple clients.

SIM Management

This enables calls to be routed normally when the bundled minutes have been used up therefore no expensive, out of bundle, Cross-Network minutes.
When Mobile Network Operators send SMS updates to their SIMS they often require a SIM reset or even take the SIM offline rendering it useless until rebooted.

SIP Services

SIP technology provides voice calls over a data connection as opposed to traditional telephone lines into your building. This requires a stable business internet service to ensure speech quality and can provide major savings on both rental and call costs, especially inter-site when linked by a telephone system where the calls are free. As SIP numbers are in the cloud they are completely flexible and in the event of a power outage etc. can immediately be directed to an alternative site.

TLD (Top Level Domain)

Also known as a domain suffix, a top level domain is the last part of a domain name, examples of which are ‘.com’, ‘.co.uk.’, ‘.net’ and ‘.org’

Unified Messaging

Unified Messaging provides alternative methods of accessing communications by merging e-mail, voice and other services. Users can get voice messages in e-mail, have e-mail dictated over the phone, or access communications via the Web.

 

UPS (Uninterruptible Power Supply)

An uninterruptible power supply (UPS) is an alternative power source that uses battery backup to maintain power when unforeseen power outages occur to aid business continuity.

VoIP (Voice Over Internet Protocol)

This is a telephone connection over the internet rather than traditional analogue telephone lines and allows people to talk internationally without having to pay long distance call charges. The data is sent digitally and requires a computer, an internet connection, VoIP software and ideally a VoIP telephone. Alternatively IP handsets can be used which connect directly to the router and contain the required software which therefore negates the need for a computer.

VPN (Virtual Private Network)

VPNs provide a secure ‘Point to Point’ network connection between your company network and remote users  which allows employees to securely access the company network from an external location. VPNs are also used to ‘link’ offices based in different geographical locations together, allowing the ability to share resources and communication across all offices securely and efficiently.

WAN (Wide Area Network)

A wide area network (WAN) usually consists of two or more local area networks (LANs) and covers a larger geographical distance.

WiFi

WiFi is a networking technology that wirelessly provides internet and network connections via radio waves.

WLAN (Wireless Local Area Network)

A local area network that uses high-frequency radio waves to wirelessly connects computers rather than wires (WLAN).
