Overview and Basic Information

Authorisation is Required

Most of the features mentioned in this manual can only be used when you have

the corresponding user authorisation. Your system administrator configures

authorisations when configuring the communications system.

Contact the system administrator when you have questions on specific features or

are not able to use a feature satisfactorily.

DECT and GAP

A digital radio connection is established between the mobile unit and the base

station (Radio Fixed Part, RFP) in accordance with the DECT standard (DECT =

Digital Enhanced Cordless Telecommunications). The digital channel ensures the

best voice quality without static or background noise. The Generic Access Profile

(GAP) is used for signalling between the communications system and the mobile

unit.

The Generic Access Profile (GAP) and the DECT standard define procedures

according to which digital cordless telephones can establish connections. The

GAP standard applies independent of manufacturer, meaning that communica-

tions systems and mobile units of various manufacturers can be combined. The

basic functions (telephoning, accepting calls) are always available in these combi-

nations; other functions (e.g. displaying the call number on the display, displaying

connection charges) which your OpenCom 1000 communications system pro-

vides along with your mobile unit, may not be available with other manufacturers’

communications systems. Please consult the corresponding manufacturer’s user

guide or contact your system administrator.
