DECTnetIP Properties ■ RFP 31/32: Access via shielded CAT5 Ethernet cable (STP cable, Shielded Twisted Pair cable) with up to 100 metres of cable from the last Ethernet switch, integrated antennas; 8 voice channels ■ RFP 33/34: like the RFP 31; mounted outside enclosed areas (IP55); external antennas ■ RFP 41/42: Access via shielded CAT5 Ethernet cable (STP cable, Shielded Twisted Pair cable); offers simultaneous function of a WLAN Access Point conforming with the IEEE 802.11b/g protocol; external antennas; 8 voice channels Note: When started, the operating software for the DECTnetIP base stations is transmitted via TFTP protocol from the OpenCom 510. The configuration for the start sequence is transmitted by the DHCP server of the OpenCom 510 to a DECTnetIP base station for the start sequence. 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. 12.1.2 Features All DECTnetIP 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 additional power supply unit. Please note: The WLAN function of the RFP 41/42 is activated when connected 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 supported. DECT encryption of calls can be deactivated for the RFP 32, RFP 34 and RFP 42 if desired. VoIP audio communication between the DECTnetIP base station and the OpenCom 510 is made via the RTP/RTCP protocol. RTP voice data are directly converted into DECT voice data by the base station. The base stations support the VoIP codecs G.711, (uncompressed) as well as G.729 and G.723 (compressed). 135
