7.6 MX+S01-8
Field of Application
The MX+S01-8 interface card provides eight 8 S
0
interfaces which can be used for
either external connections, i.e. to connect the OpenCom 510 to a digital network
(PSTN, Public Switch Telephony Network), or internal connections, i.e. to connect
digital terminals (ISDN telephones, 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 starting on page 27).
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 terminal resistor
(default: on).
For further information, refer to Termination starting on page 41.
■ 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; provided the system has
been configured accordingly, external calls can be made using an emergency
telephone.
For further information, refer to Power Failure starting on page 37.
■ All eight S
0
interfaces can be configured either as subscriber (internal) inter-
faces or as trunk (external) interfaces.
For further information, refer to S0 Ports starting on page 40.
■ The MX+S01-8 interface card can provide the system clock signalling.
■ The MX+S01-8 interface card runs on software acquired from the system. After
the card has been installed it will automatically load the required software.
