Your system administrator configures authorisa-tions when configuring the communications system.Contact the system administrator when you have questions on specific features or arenot able to use a feature satisfactorily.Further DocumentationPlease use the other included documentation on parts of your communicationssystem. This documentation is on the OpenCom 100 product CD (on the USB stickthat comes with an Aastra 800).DECT and GAPA digital radio connection is established between the mobile unit and the basestation (Radio Fixed Part, RFP) in accordance with the DECT standard (DECT = DigitalEnhanced Cordless Telecommunications). The digital channel ensures the best voicequality without static or background noise. The Generic Access Profile (GAP) is usedfor signalling between the communications system and the mobile unit.The Generic Access Profile (GAP) and the DECT standard define procedures accordingto which digital cordless telephones can establish connections. The GAP standardapplies independent of manufacturer, meaning that communications systems andmobile units of various manufacturers can be combined. The basic functions (tele-phoning, accepting calls) are always available in these combinations; other functions
