DECT over IP® Properties 10. DECT over IP® In order to achieve optimal network coverage, a DECT network with several DECT base stations can be operated. A DECT network is comprised of DECT terminals connected with the next respective base station (network cell). For users of a DECT terminal, the handover from DECT base station to base station is completely transparent. Even during a conversation, users are switched from one network cell to the next without any interruption. Administration of DECT terminals is done centrally via the OpenCom 100 Configurator in the Telephony: Devices: DECT Phones menu. Note: DECT over IP® is a registered trademark of Aastra Telecom Schweiz AG. 10.1 Properties 10.1.1 DECT Base Stations DECT base stations can be connected to the OpenCom 100 via Upn accesses or via network (TCP/IP).
