This section of the manual describes the elements of the driver that configure and control its
behavior. Included here are the constants, variables, and structures that the Narrowband Chipset
device driver uses to store initialization, configuration, and status information. For more
information on our naming convention, please see Appendix A (page 178).
Constants
The following constants are used throughout the driver code:

<Narrowband Chipset ERROR CODES>
functions and used in the global error number field of the Chipset Module Data Block
(CSMDB) and Chipset Device Data Block (CSDDB). For a complete list of error codes, see
Appendix B (page 178).
NBCS_MAX_SBS and NBCS_MAX_NSE
devices that can be supported by the driver. This constant must not be changed without a
thorough analysis of the consequences to the driver code.
NBCS_MAX_SBS_INIT_PROFS and NBCS_MAX_NSE_INIT_PROFS
number of profiles for SBS and NSE devices that can be supported by the driver.
