Serial Connection
The serial port is a 9-pin D-SUB male type. When connecting a PC to the CCFP, a
full connection DTE-DTE must be used (Figure 2.6).

Installing the CCFP
When mounting the CCFP on a wall it is important that the supplied bracket is used.
If is also important to make allowance for accessing the connecting cables via the
base of the unit.
Installing RFPs (Base Stations)
Overview
The Radio Fixed Part (RFP) is designed with two internal antennas and supports an-
tenna diversity. The RFP can also carry out a handover between the RF channels
under the same RFP, and handles four DECT speech channels simultaneously. The
RFP is able to frame synchronise with other RFPs under the same CCFP.
Transmission length is up to 2 km on 0.5mm twisted pair, e.g. cat.4, between the
RFP and CCFP. The RFP is also supplied with power from this connection (maxi-
mum supply 1.5 W). The DECT radius of coverage is up to 600 metres with a hand-
set in free sight. It is possible to connect a maximum of eight RFPs to a CCFP with-
out an expansion board, 16 RFPs with an expansion board and 32 with a link system
(using the Link card to connect two systems).
