Terminology and Abbreviations

3G

Generic term for the third generation mobile systems which will offer voice and faster data services compared to today’s 2G (e.g. GSM) and ‘2.5G’ (e.g. GPRS) solutions.

3GPP

3rd Generation Partnership Project. Collaboration between a number of telecommunications standards bodies to specify 3G. 3GPP also maintains and develops the specifications for GSM.

AMR

Adaptive Multi-Rate. 3GPP standard for speech coding (compression).

AU, .au

Format for audio data files.

AWT

Abstract Windowing Toolkit. A Java Graphical User Interface library.

Bearer

Path over which data flows. Specifically in CSD and HSCSD, the type of telephony link from the GSM network to the server – PSTN or ISDN.

Bluetooth

Bluetooth wireless technology is a secure, fast, point-to-multipoint radio connection technology. It is a specification for a small-form factor, low-cost radio solution providing links between mobile computers, mobile phones and other portable handheld devices, and connectivity to the internet. Available from the Bluetooth Special Interest Group (SIG), http://www.bluetooth.com.

Bookmark

A URL and header/title stored in the phone, enabling the user to go directly to a Web or WAP page.

bps

Bits per second – rate of data flow.

BMP

Microsoft Windows Bitmap. A graphics format defined by Microsoft supporting 1, 4, 8 or 24 bit colour depth. No compression, so files can be large.

cHTML

A version of HTML optimized for small devices.

CLDC

Connected Limited Device Configuration. The J2ME ‘configuration’ implemented in the P800. CLDC specifies a runtime environment with specifically limited resources, suitable for memory-constrained devices.

CLI

Calling Line Identity. Shows the number of the person calling you in your mobile phone display. The P800 will also display the name and photograph of the caller if they are in Contacts. You can then make an informed choice as to whether or not to take the call. Bear in mind that not all numbers can be displayed. To use this service,

it must be supported by your network.

COM Port

Defines a serial/RS-232 port within the Windows environment. May be physical (COM1 port on the rear of the PC) or virtual (COM5 port communicating with a PC card modem)

CS

Circuit Switched. Connection from A to B which has a fixed bandwidth and is maintained over a period of time, for example a voice telephone call.

CS-1 to CS-4

Coding Scheme. Determines the data rate per timeslot in GPRS.

CSD

Circuit Switched Data. CSD is a GSM service providing a CS data connection at a rate of 9.6 or 14.4kbps.

CSS

Cascading Style Sheet. A feature of browsers.

DTMF

Dual Tone Multi Frequency. A method of coding digits as a combination of two audible tones.

DUN

Dial-Up Networking.

ECML

Electronic Commerce Modelling Language.

EFR

Enhanced Full Rate, speech coding. Provides better speech quality than HR or FR.
