Overview

This chapter gives an overview of the QMC protocol including some example applications.
1.1 The QMC (QUICC Multichannel Controller)
The QMC protocol emulates up to 64 logical channels within one SCC (serial
communication controller) using the same time-division-multiplexed (TDM) physical
interface. This multichannel protocol is implemented using the CPM ROM space and
additional hardware; it is not a downloadable microcode.
The standard QUICC family members (MC683601, MPC8602, etc.) work in TDM
applications but can only support one logical channel per SCC. The parts currently
supporting the QMC protocol are a superset to the following devices:
MC68MH360 is a superset of the MC68EN3603
MPC860MH is a superset of the MPC860EN
MPC860DH is a superset of the MPC860DE
The QMC parts are pin-compatible with their respective family members. With minor
adjustments, they can be used in identical applications such as primary rate ISDN support.
1.2 Introduction
Ideal for E1/T1 applications, the QMC protocol can multiplex any 64-channel combination
of subgroups to one TDM interface.
Each of the channels can be separately programmed either to perform HDLC formatting/
deformatting or to act as a transparent channel.
Both of the SI serial interfaces (for example, TDMa or TDMb) can be dedicated to the QMC
protocol. The SI transfers the whole frame to an SCC4. Using the CPM RISC, the SCC
1MC68360 is trademarked as the QUICC.
2MPC860 is trademarked as the PowerQUICC.
3On the MC68MH360, protocol support for Centronics and BISYNC have been removed to create space for
the QMC microcode.
4This is the normal operating mode; however, it is possible to split the TDM stream over several SCCs.
