Field of Application
The MX+S01-8 interface card pro-
vides eight 8 S
0
interfaces which can
be used for either external connec-
tions, i.e. to connect the
OpenCom 510 to a digital network
(PSTN, Public Switch Telephony Net-
work), or internal connections, i.e. to
connect digital terminals (ISDN tele-
phones, ISDN fax machines etc.) to
the OpenCom 510.
The MX+S01-8 interface card can be
installed in any of the slots (1 to 12)
of the OpenCom 510 (see
Slots start-
ing on page 22).
Technical Information
■
The MX+S01-8 interface card
can also be installed in a slave
system.
■
DIP switches S1 to S16 can be
used to activate a 100-ohm ter-
minal resistor (default: ON).
For further information, refer to
Termination starting on page 35.
■
The power failure circuit can be
activated by means of DIP
switches S17 to S20 (default:
off). If activated, the system will
connect the first S
0
interface
with the eighth S
0
interface in
the event of a power failure; pro-
vided the system has been con-
figured accordingly, external
calls can be made using an
emergency telephone.
For further information, refer to
Power Failure starting on
page 31.
■
All eight S
0
interfaces can be
configured either as subscriber
(internal) interfaces or as trunk
(external) interfaces.
For further information, refer to
S0 Ports starting on page 34.
■
If the MX+S01-8 interface card is
being used in the master system
of a cascaded configuration, it
can provide the system clock sig-
nal.
For further information, refer to
PBX Networking starting on
page 102.
■
The MX+S01-8 interface card
runs on software acquired from
the system. After the card has
been installed it will automati-
cally load the required software.
