Called a fax in common use. The digitisation of an image and then transmission of that image. Superseded the Telex.

Feature of a mobile phone which allows data to be sent and received as per fax protocols.

Telstra product. Duet refers to the addition of a second line which shares the same telephone line as an existing service. Line rental for the second line is minimal (around $6.00). Faxes may still be received while the line is busy, and are queued at the exchange until the line is free. FaxStream Duet has become a valuable tool for many small businesses.

US body for the Regulation of interstate communications: licenses, rates, tariffs, standards, limitations, etc.

A high-speed (up to 100Mbps) LAN ANSI standard for a fibre optic connection.

Multiplexing protocol where the available transmission frequency range is divided into separate channels. Data is segmented and transmitted over these various channels. Data is reconstructed at the destination.

Grouped glass, plastic or hybrid fibres which are used to transmit digital pulses of light for data transmission. High bandwidth solution which may carry voice, video and data. Commonly called `Cable`.

Delivery of calls to a user through multiple numbers at the same time such as desk phone, mobile phone and home phone simultaneously allowing the customer to pick up the call regardless of location. Available on Total Business Connect (TBC) Service.

Hardware and/or software designed to prevent unauthorized access to (or from) a private network. Firewalls are commonly positioned between the internet and all internal infrastructures (PCs, LAN, Intranet, etc.).

Is a fee that can be charged upon successful connection between a mobile and another phone. Flagfalls vary depending on the plan.

Delivery of calls to a user through an alternate network (while that user is out of range from their pre-selected network or whilst that user has requested the routing). See also Roaming.

Typically used for LAN to LAN data connection over distances, frame relays are prescribed connection paths. The end user experience is a (virtual) permanent connection between LAN sites. Frame relay is a protocol for variable-length packet transmission of data. Designed for use as a low-noise connection, redundant- and dark- data are not generally used, which leads to high transmission rates. Frame relays may transmit bursts of data at up to 45Mbps. Due to its transmission burst nature, frame relays are not ideal for transmission of continuous signals such as voice and video.

1800 Number. A FreeCall number is a Toll-Free number but with no connection charges. The call is charged to the owner of the number. As with all toll-free numbers, the call is routed to a nominated answering point. The answering point itself may be dynamic; it may be dependent on time of day (TOD), caller location, or calling traffic overflows.

Process for transferring files over the internet or another TCP/IP network. FTP is also often used to describe the software interface used for transfers. Files available to be shared are held on a server. Users may be required to logon to the server using either a secured username and password or by an `anonymous` logon (an unsecured and generic logon). Files may then be downloaded from the server (or uploaded, if permitted).
