The Features of Your Telephone

DECT and GAP

Your handset uses a digital radio connection in accordance with the DECT (Digital

Enhanced Cordless Telephone) standard for the connection to the base station. The

digital channel guarantees superior voice quality without static or background noise.

For signalling between the communications system and the handset, the

OpenPhone 28 uses the Generic Access Profile (GAP).

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

digital cordless telephones to establish connections. The GAP standard is not manu-

facturer-specific so it is possible to combine the communication systems and

handsets of different vendors. The basic functions (making and receiving calls) are

always possible with in these combinations, but other functions provided by your

OpenCom 100 / Aastra 800 communications system together with your handset

(e.g. display of call numbers or call charges) may not be available when communica-

tions systems produced by other manufacturers are used.

Depending on the digital transmission in the frequency range used and also on the

technical environment within the range of coverage, silent zones may occur. In this

case, transmission quality can be diminished by multiple, short transmission gaps.

Slight movement out of the silent zone will restore typical transmission quality. The

connection will be lost if the handset is moved out of range.

In order to avoid radio coupling into other electronic equipment, we recommend the

maximum possible distance (min. 1m) between the handset and other devices (e.g.

radios, loudspeakers etc.).

Before using the handset, people with hearing aids should note that radio signals can

couple into hearing aids and if strong enough can cause an unpleasant buzzing

sound.
