Head-end accessories

The user has the option of remotely programming and maintaining head-end devices. Depending on
the use of bus controllers different possibilities are offered: analogue modem, GSM-modem or
connection via IP. These added features save the network operator service costs, e. g. when changes
occur in transponder assignments. They imply rapid response in the event of processing card failure
by replacement signal switching. In order to activate the backup signal circuit, the network operator
merely has to select the failed module and the backup module redundancy. A renewed manual
configuration of the operating parameters for the redundancy module is not necessary.
The following processes are carried out in an automated manner:
Via a menu for detail adjustments all relevant
parameters of signal processing can be configu-
red for every head-end module. The options are
clearly arranged and assorted according to input
and output parameters. Input parameters can –
depending on the module – be entered manually
or carried over from the satellite data base in a
user friendly manner. Output parameters can be
adjusted as needed. Depending on the module the
level adjustment occurs electronically and different
options for the output signal can be activated or
deactivated.
If error messages should occur, these are
displayed in the detail menu as well.
