Configuration Option Sets
This section discusses the modem’s preconfigured option sets, in three parts:
• What is an Option Set?
• How to Configure an Option Set
• Option Set Defaults—326X V.32bis, 326XFA ST V.34, and 326XFA S T-SDC
What is an Option Set?
Option sets are complete configurations, each tailored for an application and stored
in memory. Option sets get the modem working quickly.
If an option set does not exactly suit your needs, pick the one that most closely
matches your application, modify its settings, and save the changes in the modem’s
nonvolatile memory (refer to Appendix A).
Table 4-1 shows V.3bis and V.34
option sets. Table 4-2 shows SDC option sets.
