Safety precautions
Read the safety precautions and the user guide before use.
The device cannot be used in the event of a power failure. In case of a power failure it is also not
possible to make emergency calls.
Emergency numbers cannot be dialled if the keypad/display lock is activated!
Use only rechargeable batteries that correspond to the specification. Never use a conventional
(non-rechargeable) battery or other battery types as this could result in significant health risks and
personal injury. Rechargeable batteries, which are noticeably damaged, must be replaced.
The handset must not be operated if the battery cover is open.
Do not use the devices in environments with a potential explosion hazard (e.g. paint shops).
The devices are not splash-proof. For this reason do not install them in a damp environment such
as bathrooms or shower rooms.
Use only the power adapter indicated on the device.
Whilst charging, the power socket must be easily accessible.
Use only the cable supplied for LAN connection and connect it to the intended ports only.
Remove faulty devices from use or have them repaired by our Service team, as these could interfere
with other wireless services.
Do not use the device if the display is cracked or broken. Broken glass or plastic can cause injury to
hands and face. Send the device to our Service department to be repaired.
Keep small cells and batteries, which can be swallowed, out of the reach of children.
Swallowing a battery can lead to burns, perforation of soft tissue anddeath. Severe burns can occur
within 2 hours of swallowing.
In the case of a swallowed cell or battery, seek medical care immediately.
Using your telephone may affect nearby medical equipment. Be aware of the technical conditions
in your particular environment, e.g. doctor's surgery. If you use a medical device (e.g. a pacemaker),
please contact the device manufacturer. They will be able to advise you regarding the susceptibility
of the device to external sources of high frequency energy.

Introduction
This document explains the preparations necessary to install a multi-cell DECT network and take
measurements for the optimum positioning of the base stations. It also provides technical and
practical background information.
The COMfortel WS-500M Multi-Cell System
The COMfortel WS-500M multi-cell system is a DECT multi-cell system for connecting DECT base
stations to a VoIP PBX. It combines the options of IP telephony with the use of DECT telephones.
Components
The following figure shows the components of the COMfortel WS-500M multi-cell system and
how they are embedded in the IP phone environment:
The currently available extension levels of the multi-cell system only support the
combination of Integrator and DECT Manager within one device. Additional DECT
Managers are not supported.

•DECT integrator
Central management and configuration unit of the DECT multi-cell system.
The DECT integrator
•integrates the base stations of multiple DECT managers in one roaming domain
•contains the central database for the DECT subscribers
•provides a web interface for configuring the subscribers
•enables access for configuration of all DECT managers and the synchronisation hierarchy
of the base stations
In small and medium-sized installations, the integrator and DECT manager are on the same device.
For large installations, the integrator is provided as a virtual machine.
•DECT manager
Management station for a group of base stations. At least one DECT manager must be used
in every installation. Up to 100 DECT managers can be used in large installations.
The DECT manager
•manages synchronisation of the base stations within clusters
•acts as an application gateway between SIP and DECT signalising
•controls the media path from the phone system to the relevant base stations
•DECT base stations
•form the wireless cells of the DECT phone network
•provide media processing from the handsets directly to the phone system
•make available connection channels for the handsets (the number is dependent
on various factors, such as bandwidth approved) (refer to Section Capacity ¢P. 10)
•Handsets
•Up to 250 handsets can be connected per DECT manager; up to 60 DECT calls can be held
simultaneously (VoIP calls, and phone book access). Information on the functions of
certain handsets on COMfortel WS-500M is available from wiki.auerswald.de.
•Subscribers can accept or initiate calls in all DECT cells with their handset (Roaming),
and can also switch between the DECT cells during a call (Handover). A handover is only
possible when the cells are synchronised.
•Phone system
Connect your DECT phone system to a VoIP phone system, e.g.:
•your own PBX (on-premise solution)
•a virtual phone system from an external provider (Cloud solution, hosted PBX)
•VoIP provider
The phone system
•establishes the connection to a public phone network
•enables central management of phone connections, directories, network mailboxes, ...
