Ports
U
pn
ports can be used to connect
one of the following system terminal
types:
■
RFP 21 DECT base station
■
OpenPhone 61, OpenPhone 63
or OpenPhone 65 system tele-
phone
■
OpenPhone 52 ISDN system ter-
minal
The (corded) OpenPhone 63 and
OpenPhone 65 system telephones
can be cascaded by means of a U
pn
adapter, which enables you to con-
nect two OpenPhones to one U
pn
port. For further information, refer
to the “OpenPhone 61, 63, 65” user
guide.
The RFP 21 DECT base station can be
used to connect the OpenPhone 21
and OpenPhone 25 DECT handsets.
The OpenPhone 25 has a V.24 inter-
face for data transmissions and In-
ternet access. Note that handsets
such as the OpenPhone 21 can also
be used in conjunction with base
stations operating with the GAP/CAP
standard.
Note on the MS+UPN2-8
Interface Card
U
pn
interfaces can only be used to
connect DECT base stations if the
MS+UPN2-8 has been installed in
the master system; if this card is in
the slave system, it is not possible to
connect any DECT base stations to
the card’s U
pn
interfaces.
Note on the MS+UPN1-8
Interface Card
The U
pn
interfaces of the
MS+UPN1-8 interface card cannot
be used to connect DECT base sta-
tions.
Technical Information
The U
pn
ports have been imple-
mented as RJ45 sockets.
Each of the devices listed above can
be connected to the U
pn
interface by
means of a two-wire 1:1 cable. Sys-
tem terminals come with a suitable
cable for connection to the RJ45
socket of the interface.
A two-wire cable connected to a U
pn
port can be up to 1000 m long, pro-
vided it is a 0.6 mm twisted-pair ca-
ble.
Each U
pn
port has a power feed of
approx. 3 W. The short-circuit-proof
feed voltage is
–
42 V.
