Internal/External
S Ports
0
All S ports can be operated exter-
0
nally, i.e. on an ISDN network termi-
nation unit. The S
sic module and all S
additionally installed interface cards
can also be connected internally. It is
not possible to use both assign-
ments simultaneously.
Up to eight devices per bus (ISDN
telephones, ISDN fax machines, ISDN
base stations, ISDN cordless tele-
phones, ISDN adapters for the PC)
can be connected to the internal S
ports by twin-pair cables. The power
for three of these devices can be
supplied by the bus; if more devices
are used, they then require their
own power supplies. The internal S
buses enable point-to-multi-point
calls as per the DSS1 protocol (Euro-
ISDN).
U Ports
pn
A system terminal can be connected
to every U
ble. The OpenPhone 61, OpenPhone
63 and OpenPhone 65 are cord-
bound system terminals. The Open-
Phones 63 and 65 can be cascaded
on a U
pn
erate two OpenPhones on one U
port. For further details, refer to the
"OpenPhone 61, 63, 65" user guide.

The RFP 21 base station is required
for the use of cordless system tele-
phones (e.g. OpenPhone 21 or
OpenPhone 25). The OpenPhone 25
features a V.24 port on which you
can transfer data and surf on the In-
ternet.
If this base station is connected to a
U port of an interface card, four si-
pn
multaneous calls are possible with
the mobile parts. If the base station
is connected to two U
simultaneous calls are possible.
However, note that only as many ex-
ternal connections are possible as
there are connected B-channels

available.
If you use a cordless handset such as
the OpenPhone 21, this can also be
contacted by other base stations us-

ing the GAP/CAP standard.
You can also operate the
OpenPhone 52 ISDN terminal on a
U port.

Note: DECT base stations cannot be
operated on the U
