3. Rename signalstandards.txt to userstandards.txt .
4. Edit the contents of the file to suit your systems settings.
When editing your userstandards.txt file, it is safer to copy a row and
then edit the copied row to meet your requirements than to modify
an existing row.
Table 2--12 lists the elements of the Channel Table file.
Table 2- 12: Channel table file contents
Column heading Description
Standard Name The text string used to identify the standard. This name is
what appears in the Signal Standard list.
Each line in the channel table should describe a single
group of channels for a standard. If a standard is made up
of multiple groups or blocks of channels then you should
make an entry for each group. When multiple groups are
required, they should be ordered in channel number
sequence and contiguous. To tie the groups together, the
Unique Standard ID must be the same for each group.
Forward Base Frequency Forward base frequency for each signal standard. The
actual frequency for each channel is calculated.
For signal standards that specify a single frequency for each
channel (for example, the UTRA/FDD scheme used by
W-CDMA (UMTS)), each row in the file will describe a
group of forward or a group of reverse channels. The row
that describes forward channels should specify zero for the
reverse base frequency. The row that describes reverse
channels should specify zero for the forward base
frequency.
