BSCTRAN Programmer’s Guide
For a detailed view of a sample Freeway server dlitrancfg file, refer to Section 7.1 on
page 104. Note how in our example, the session definition properly indicates that the
desired ICP board number is 0 and the desired link number is 2. Also note that the
Transport parameter indicates a connection name of bsc0. The Freeway software uses
the connection name to find the server name. To do so, the Freeway software checks the
tsitrancfg file and locates the section that defines the designated connection. In our
example, it would locate the following section:
bsc0
{
.
server = "freeway0"; // Server name //
.
For a detailed sample tsitrancfg file (for a Freeway server), refer to Section 7.2 on
page 107. Note how in our example, the connection definition properly indicates that
the desired server name is
freeway0.
For the embedded ICP boards (using DLITE), the Simpact-supplied DLI configuration
file (
dlitetrancfg) does not reference Simpact Freeway servers, and thus does not ref-
erence a TSI configuration file. The proper ICP and link are, however, defined exactly as
in any DLI configuration file.
In summary, the BSCTRAN software combines the information in a BSCTRAN com-
mand into a session name and then looks up the definition of that session in the
dlitrancfg or dlitetrancfg file. It uses the session definition to determine the desired
link and ICP board. Using this information, the Freeway software can then route the
data to the desired link on the desired ICP.
Figure 2–1 shows two example BSCTRAN commands and the way in which the infor-
mation in the commands determines the data path. Note that for DLITE, the
“
transport” parameter is ignored in dlitetrancfg.
