| G.733 | Characteristics of primary Pulse Code Modulation (PCM) multiplex equipment operating at 1,544Kbit/s | |
| G.DMT | A BT term. Wires only presentation | |
| GAP | i) Generic Access Profile. A European standard which ensures that a DECT handset can be used with other manufacturers’ DECT systems. GSM Conformance will become mandatoryGateway ii) A device which operates at the highest layer of the OSI model, performing protocol conversion, thus enabling interconnection of dissimilar networks |
|
| Gateway | A Gateway is a network point that acts as an entrance to another network. In a company network, a proxy server acts as a gateway between the internal network and the Internet. A gateway may also be any machine or service that passes packets from one network to another network in their trip across the Internet. | |
| GBIC | Gigabit Interface Converter. A standard for transceivers, commonly used with Gigabit Ethernet and fibre channel. By offering a standard, hot swappable electrical interface, one gigabit ethernet port can support a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of hundreds of kilometers. The appeal of the GBIC standard in networking equipment, as opposed to fixed physical interface configurations, is its flexibility. Where multiple different optical technologies are in use, an administrator can purchase GBICs as needed, not in advance, and they can be the specific type needed for each link. This lowers the cost of the base system and gives the administrator far more flexibility. On the other hand if it is known that a switch will mostly have one port type (especially if that port type is copper) purchasing a switch with that port type built in will probably be cheaper and take up less space per port. The GBIC standard is non-proprietary and is defined by the SFF Committee in document #SFF-8053. |
|
| GE | A du Pré term. An abbreviation for Good Evening | |
| GHz | Giga Hertz. 1,000 MHz | |
| GIF | Graphic Image File format. A compressed graphics format | |
| Gig or Giga | 2 to the power of 30 = 1,073,741,824. Sometimes used, incorrectly, to approximate a thousand million | |
| Gigabit Ethernet | A new Ethernet network protocol, which can send data across the network at up to 1000Mbit/s, currently the fastest on the market | |
| GLOBAND | Global Bandwidth On Demand Consortium. Introduced wideband ISDN in response to interest in bandwidth on demand | |
| GMT | Greenwich Mean Time | |
| Good Evening | An evening salutation on meeting or departing. In addition, the du Pré sales department's salutation regardless of time of day, often, when written, abbreviated to GE | |
| Good Fiddling With | A JE of du Pré expression, meaning programming and or mechanical repair, is required | |
| Good Ignoring | A JE of du Pré expression. To look down one's nose disdainfully at something or someone and ignore what has either been said or done. To show contempt. Will, without doubt, be followed by a "good leaving alone" | |
| Good Leaving Alone | A JE of du Pré expression, meaning no action required or needed, whatsoever | |
| Good Staring At | A JE of du Pré expression. To carry out a full technical evaluation or fault analysis without interfering or touching the equipment or person concerned. May well be followed up with a "good leaving alone" or a "good fiddling with" | |
| Gopher | A way of finding information on the Internet, which is in decline due to the rise of the web and search engines | |
| GoS | Grade of Service is the probability of a call being blocked or delayed by more than a specified interval. This is always with reference to Busy Hour when traffic density is at its greatest. Specifically applies to a circuit group and not a single circuit. When referring to a single circuit, the term becomes Quality of Service. |
|
| GPRS | A cellular radio term. General Packet Radio Service. A packet switching technology for GSM networks. It's an advanced data transmission mode that does not require a continuous connection to the Internet, as with a standard home modem. Instead, GPRS uses the network only when there is data to be sent, which is more efficient. The "GSM Association" believes using GPRS will enable users to send and receive data at speeds up to 115Kbps, more than two times faster than with traditional home modems | |
| Grade of Service | See GoS. | |
| Green Circle | A BABT approved piece of equipment must be labelled. The label must state the equipment’s ‘approval number’, and show a large Green Circle | |
| Group 4 Fax | Faxes for use on the ISDN, only, offering high speed transmission. Typically 4 seconds per page | |
| GroupLink | A BT term. Associted with BT's Advanced Features. Individual callers can be 'identified' and treated accordingly. Gateway access for closed user groups. | |
| GroupWare | A generic term used to describe software written specifically for NetWare, the Novell network operating system | |
| GSM | A cellular radio term. Global System for Mobile Communications. Considered the most advanced digital cellular technology, extremely popular in Europe and Asia. GSM networks are leaders in many typically "digital" services including the SMS, OTA configuration and GSM positionning. Considered its technology and presence both in Americas and the rest of the world, GSM is in a good position for global roaming and many new GSM phones are called "global phones", since they can be used in virtually any country. The SIM card ("Subscriber Identification Module") is also a unique and essential component of GSM phones. GSM was built based on the TDMA protocol | |
| GUI | Graphical User Interface. Sits between the program and the user, making it easier to use. For example, Icons represent typed commands |
