Purpose

This chapter outlines the PPL components in the SS7 stack of the CSP system software that are available for customizing within the following SS7 modules:

• L3P

• ISUP

• TUP

• L3P SSUTR2

• BT IUP

• MTP3

• MTP2 TXC (0x26)

• SCCP/TCAP

Important! Unless indicated otherwise, it is assumed that all configuration bytes are part of Block 1

With each module, specific information can be found within PPL component IDs according to ITU and/or ANSI standards: Configuration Bytes, PPL Events and PPL Timers. For some components, only PPL Timers can be changed.

For an explanation of PPL formats and configuration, see the Developer’s Guide: Overview.

For a list of the PPL Components and addressing information, see PPL Component IDs and PPL Component Addressing in the API Reference.
