DECT over IP
®
143
If VoIP telephony is already being used, Ethernet cable access makes good sense.
Transmission of telephony signalling and voice data via TCP/IP also offers usage of
existing network infrastructure and an increase in range using suitable methods. VPN
connections, for example, can be used for data links to provide service to remote or
hard-to-reach locations.
Note
The DECT base stations RFP 32/35, RFP 34/36/37 and RFP 42/43 support the DECT
encryption function. This feature is however, only available if all the DECT base sta-
tions support it.
Features
All DECT over IP base stations can be connected to a CAT5 Ethernet cable with a 10/
100 Base T. Power is supplied either via Power-over-LAN (IEEE 802.3af ) or via an addi-
tional power supply unit. A base station of the type RFP 34 can only be supplied via
PoE.
Please note: The WLAN function of the RFP 42 is activated only when con-
nected to the 100 Base T.
DECT terminals offer all system telephony features. DECT telephones supporting the
GAP standard can also be operated. Transparent GAP device handovers are sup-
ported. DECT encryption of calls can be deactivated for the RFP 32/34/42 and RFP 35/
36/37/43 if desired.
VoIP audio communication between the DECT over IP base station and the
OpenCom 100 is made via the RTP/RTCP protocol. RTP voice data are directly con-
verted into DECT voice data by the base station. The base stations support the fol-
lowing VoIP codecs:
G.711 uncompressed
G.723 compressed
G.729 compressed
