Telestra Software Functionality Part Numbers (#144)

ASTi has transitioned its Telestra software part numbering system to a standardized format. As of 2025, all Telestra software part numbers (compatible with Telestra 4.X and later) use the SF prefix, which stands for Software Functionality. This replaces the previous ACE naming convention:

• ACE-MPL-NNNN (model credits) → SF-NNNNNN (model credits)
• ACE-XXX (software packages) → SF-XXX (software packages)

Telestra software part numbers follow two formats:

• SF-XXX: feature-specific software packages (where XXX represents alphabetic characters identifying the software type)
• SF-NNNNNN: credit-based licenses (where NNNNNN represents the number of credits)

Note: Feature identifiers (the alphabetic portion) may vary in length depending on the specific software package.
