Purpose
This section includes ITU and ANSI PPL Config Bytes, all PPL Events, and Timer information for the PPL Component ISUP SPRC.
ISUP SPRC Configuration Bytes (ITU)
You can modify the parameters for Config Bytes 1–4, but you cannot move them to other byte locations. Other functions in the system access these parameters.
