Switching DECT On and Off

Overview

With the "DECT enabled" setting you can switch the DECT base station on and off.

Rules

• "DECT enabled" is enabled automatically whenever you register a DECT device (cordless telephone, Smart Home device) with the FRITZ!Box.
• "DECT enabled" is disabled automatically when no more DECT devices are registered.
• If you disable "DECT enabled", the connections to the registered DECT devices will be cleared. The devices will be reconnected when you enabled "DECT enabled" once more.

Changing the PIN

Overview

The preconfigured PIN for registering DECT cordless telephones like FRITZ!Fon is set to "0000" in the FRITZ!Box. You can also specify a different PIN.

Rules

• Automatic registration of FRITZ!Fon cordless telephones works only with the preconfigured PIN "0000". If you change the PIN, you have to enter the PIN to register a new FRITZ!Fon cordless telephone.

Using Expanded Registration Mode

Expanded registration mode is a special registration mode for DECT devices that are already known to the FRITZ!Box but no longer connected to it. In expanded registration mode you can register multiple DECT devices (for instance, FRITZ!Fon, FRITZ!DECT) in sequence. You do not have to restart registration on the FRITZ!Box for each DECT device.

Reducing Field Strength and Enabling DECT Eco

Overview

To reduce the radiation of the DECT radio network, you can reduce DECT transmission power and enable DECT Eco.

When DECT Eco is enabled, the FRITZ!Box switches off the DECT radio network as soon as all cordless telephones are in standby mode. The connection to the cordless telephones is maintained, however. When a call arrives or you press a key on a cordless telephone, the DECT radio network is switched back on.

Requirements for DECT Eco

• All of the registered cordless telephones must support DECT Eco. In the user interface, the option "DECT Eco supported" must be displayed for each telephone under "DECT / DECT Monitor".
• The following devices must not be registered with the FRITZ!Box: FRITZ!DECT devices with an outlet switch, FRITZ!DECT Repeater, another FRITZ!Box in DECT repeater mode.

Configuring Security Functions

Overview

The FRITZ!Box is preconfigured to allow only authenticated and encrypted DECT connections. For these connections you can enable or disable the expanded security functions early encryption and re-keying.

In order to use DECT repeaters from other manufacturers that do not allow encrypted connections, you can allow non-encrypted connections.
