SINTRAN III Logical Device Number Reference
All logical device numbers used by SINTRAN III, from 0₈ through 3377₈ (0-1791 decimal).
Source: Appendix B of ND-860228-2-EN "SINTRAN III Monitor Calls"
Overview
Logical device numbers are 11-bit values (0-3777₈ = 0-2047 decimal). They are organized into 32 groups of 64 entries each via the LDNT (Logical Device Number Table). The logical device number encodes the group and entry index:
Logical device number = group_index * 64 + entry_index
= group_index * 100₈ + entry_index
