IDA (In-Direct Access) - A coding used by carriers to facilitate calls via their networks.

Internet - The Internet is a worldwide collection of computer networks, working together to exchange data using a common software standard – usually HTTP. Nobody owns the Internet – so it is bound by few rules and answers to no single authority.

IP (Internet Protocol) - It’s a standardised method of transporting information across the Internet in packets of data. It is often linked to Transmission Control Protocol, which assembles the packets once they have been delivered to the intended location.

IP Address - IP is short for Internet Protocol, and an IP Address is a set of four numbers that are basically the virtual address of the computer you are using – a unique identifier if you like. Your Internet Service Provider (ISP) will assign your computer with a temporary IP address purely for when you are connected to the Internet. If you disconnect and reconnect later, you will be assigned a new IP address.

IP Telephony - Using Internet Protocol as a method of carrying voice calls. With IP, voice communications (in the form of IP packets) are routed directly from the origin to destination devices.

IP VPN - A virtual private network (VPN) is a computer network that uses a public telecommunication infrastructure such as the Internet to provide remote offices or individual users with secure access to their organization's network. It aims to avoid an expensive system of owned or leased lines that can be used by only one organization.

It encapsulates data transfers between two or more networked devices which are not on the same private network so as to keep the transferred data private from other devices on one or more intervening local or wide area networks. There are many different classifications, implementations, and uses for VPNs.

ISDN (Integrated Services Digital Network) – It’s a digital telephony service that gives better call quality, quicker connection times and DDI facilities. ISDN is generally provided to connect to a customer’s PBX. ISDN can also be used in Radio and was historically used for faster Internet connection before the advent of broadband.

ISDN2e – This digital telephony service is provided in pairs i.e. 2 channels/lines per ISDN2e. For offices with 2 - 8 concurrent users, ISDN2e allows for up to 8 simultaneous calls into or out of your business. The e stands for the European standard.

ISDN30e - This digital telephony service is provided over one large circuit (bearer/pipe) either as copper or in many cases fibre optic. Designed for larger offices whom expect to make or receive over 8 simultaneous calls. The minimum number of channels/lines one can have is 8 moving up to 30. Larger organisations can rent multiple ISDN30e’s should they require more lines. The e stands for the European standard.

ISP (Internet Service Provider) - Your ISP is the company that supplies your connection to the Internet. In our case, it would be our recommended ISP.

L

LAN (Local Area Network) – It’s a data network that connects computers, servers, printers etc together, generally within one physical location.

Landline (aka Analogue line or PSTN) - Your landline is the fixed analogue telephone line, which you can receive your broadband and phone services through. It is often used as a facsimile line. See also analogue line and PSTN.

Leased Line – It’s a dedicated private internet access circuit – provides secure, fast and unrivalled internet access.
