DIGITAL STD – WCDMA/3GPP – BS CONFIGURATION / channel table menu
Below the general parameters of the current base station follows a table comprising all the parameters
that can be edited on a channel-specific basis.
CH NO
Channel number, consecutive from 0 to 138. This value cannot be edited. All
rows are displayed even if the channels are inactive. Activating/deactivating is
via STATE at the end of the row.
TYPE
Channel type which is permanently linked to the channel number and which
cannot be edited:
The first 11 code channels in the table are occupied for the special channels
P-CPICH to DL-DPCCH. All other code channels are DPCHs. The channel
type is a pure display parameter and cannot be edited. Not all parameters in
the table can be edited. This depends on the type of channel.
SYMBOL RATE
Symbol rate of channel in ksps.
The value range of symbol rate is modified depending on the channel type.
For example, the P-CPICH is fixed at a symbol rate of 15 ksps by the 3GPP
standard, but all symbol rates between 7.5 ksps and 960 ksps are available for
a DPCH.

CHANNELIZATION
CODE
The channelization code (previously called spreading code number) is
selected here. The code channel is then spread with the channelization code
(spreading code) thus determined. The value range of the channelization code
depends on the symbol rate of the channel. A fixed channelization code is
allocated to a few channels as standard (the P-CPICH e.g. always uses the
channelization code 0).
The maximum value range extends from 0 to
