<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.
