3.2. Front page
The relevant information required for the function of the system are shown on the front page. The decisive
thing is the quality of the signals at the INPUT and the utilization of the modulators at the OUTPUT.
3.2.1. Input
The bit error rate BER of all tuners is shown on the left side. The amount of bit errors for the last 1,000,000
transferred bits is calculated.
Also the LEVEL and the C/N ratio are shown.
3.2.2. Outputs
The fill level of all modulators is shown. 100% modulator fill level correspond to the maximal net data rate of
the output channel.
If the current fill level exceeds the maximal fill level, it may cause image disturbances, e.g. mosaic images.
The data rates of the programs are not constant. They are dynamically changed by the sender. To ensure an
undisturbed reception, a reserve must absolutely be observed.
We recommend you to set the maximal fill level to 90%.
From a fill level of 95%, this is indicated in red.
The number of choosen programs (see 4.2 on page 21) and the configuration of the modulators (see 4.3 on
page 34) have an influence to the fill level.
3.2.3. Allerts
If allerts, warnings or messages of the head-end are active, then these are displayed on the start page after
logging in.
