Purpose
This section includes ITU and ANSI PPL Config Bytes, all PPL Events, and Timer information for the PPL Component ISUP CPC.
Use of Blocks
Blocks are used to organize the PPL configuration bytes. Each block does not exceed 200 configuration bytes. The ISUP CPC component has three blocks of configuration bytes. These blocks must be reference when using the bytes.
