In the 'Backup Settings' mode you can allocate an entry of
the ISDN directory to each input port of the Alarm/Control
Interface.
To do this, you must select the requested input port. Press
the ‘Cfg’ (Configuration) key to allocate an ISDN number
to this input port.
This ISDN number complies in all parameters to the re-
spective entry in the ISDN directory.
In the following example, the entries IN1 to IN 4 for back-
up are utilised.
The entries IN5 to IN8 have not been allocated and are
transmitted transparently to the opposite side. A feedback
to confirm whether connection has been established takes
place over the respective outputs of the Alarm/Control
Interface. When, for example, a connection has been
established with IN2, the output OUT2 is activated once
the connection has been established and the decoder has
been synchronised.
Further information on applications of Backup Settings can
be found on page 75.
To do this the ‘No X.21 clock’ must be activated. Enter
with the corresponding Cfg button, the ISDN number of
the partner unit which should be dialed in case of error.
The desired configuration is also entered.
