Installation of the IPBL
INSTALLATION GUIDE
IP-DECT Base Station and IP-DECT Gateway
4.2.2 RFP Cable
The RFP cable connects the IPBL with the RFPs. The maximum cable length between IPBL and a single RFP
must not exceed 1500 meters.
Ensure that during the installation, each RFP is given an extra length (5-10 metres) of cable
because it is possible that it will have to be moved for one reason or another.
1. Cut the cable to the correct length.
2. Connect the cable to a RJ45 modular jack. For information on the pinning, see below.
If local power supply is used for the RFP, the EPP cable pairs must NOT be connected.
