This display shows at a glance whether assigned code domains of various channels overlap, i.e.
whether a domain conflict occurs. The symbol rates of code channels are indicated by the width of the
associated bars. The height of the bars gives the power of the code channel. If a bar is grey, the code
domain at this position is assigned once which means that no conflicts occur. If a bar is black (at least
partly), the code domain is assigned at least twice and conflicts occur.

Display of domain conflicts
If a domain conflict occurs in the base station/mobile station, this conflict is displayed at two locations
(next to the code domain display).
1. Centrally for the whole station in the status line
,
2. All lines in the channel table (processed in ascending channel numbers) showing a domain conflict
in a row with a lower index are indicated with a warning symbol
to the left of STATE.
A domain conflict occurs when the assigned domains of different channel rows overlap. The assigned
code domain of a channel is calculated from the symbol rate of the channel, the minimum possible
symbol rate (depending on the link direction), the chip rate and the channelization code number using
the following equation:
symbolrateimum
symbolratecurrent
factorDomain
_min
_
_ = (the minimum symbol rate is 7.5 ksps in downlink),
where:
Lower domain limit = current channelization code number * domain factor
Upper domain limit = lower domain limit + domain_factor –1.
If the cursor is positioned on one of the warning symbols
and if the SELECT button is clicked, a window
is opened and shows more accurate information about the domain conflict that has occurred. The numbers
of channel rows in the channel table and the assigned domains of the conflicting channels are displayed.
