Assigning lines for data traffic

The number of lines you assign for data traffic determines the bandwidth of your data networking
connection. The following table shows the available bandwidth for data traffic on the UTWAN
according to the number of lines assigned.

Table 19 Bandwidth available per channel

Note: The maximum number of lines you can assign for data traffic is 16.
Both ends of the WAN link must be using the same number of lines for data traffic and
start with the same time slot.
To assign a line for data traffic, you must change the line type to Fixed Data Channel and then
assign the line to the data module.

Determining which lines are available to the UTWAN

The lines that are available to the UTWAN are determined by the DIP switch settings on the DTM
you are using for the UTWAN connection. Refer to the table below for a list of lines assigned per
DS30 bus.
