Overview of T1 configuration
Table 7-1 lists the sections describing common tasks you might have to perform to configure a 
T1 line. The table includes a brief description of each task and lists the parameters you will 
use. 
For information about administering the T1 card, including such tasks as specifying a facilities 
data link (FDL) and displaying the status of the lines, see the APX 8000/MAX TNT/DSLTNT 
Administration Guide.
For complete information about the associated parameters, see the APX 8000/MAX
