Signaling System 7 (SS7) Protocol Microcode User's Manual for MC68360 QUICC
User manual for MC68360 SS7 microcode providing features for Signaling System 7 protocol layers, including FISU/LSSU filtering, error monitoring, and HDLC functionality.
Overview
This technical manual describes the Signaling System 7 (SS7) protocol microcode designed for the NXP MC68360 Quad Integrated Communications Controller (QUICC). It outlines the SS7 controller architecture, specifically focusing on the Message Transfer Part (MTP) layer 2 functions. The microcode enhances basic HDLC functionality to handle SS7-specific tasks such as continuous transmission of Fill-In Signal Units (FISUs) and Link Status Signal Units (LSSUs), Signal Unit (SU) filtering, and error rate monitoring. The document provides detailed technical specifications for the SS7 programming model, including transmit and receive commands, memory mapping, buffer descriptor configurations, and specific register settings for octet counting and error handling. Additionally, it includes microcode initialization procedures for various QUICC hardware revisions.
Use Cases
- Implementing SS7 data link layer functions in public switching telecommunications networks.
- Configuring the MC68360 QUICC for automated FISU and LSSU filtering to reduce CPU overhead.
- Developing communication protocols requiring high-reliability signal unit error monitoring and alignment.
