8.1. GENERAL DESCRIPTION
The control system of this unit is composed of the main control section (MPR) controlling the
entire system, exchanging voice data, the circuit control section (LPR) controlling various
telephone lines and the power supply section (POWER).
MPR, LPR and POWER are connected each other through the System BUS (ADDRESS BUS,
DATA BUS and CONTROL BUS). MPR LPR are under I/O control (I/O Read/Write) by MPR.
MPR controls LPR which has a microprocessor by the lnter-Microprocessor Communication
System supported by ASIC. That is, MPR and LPR exchange controlling messages through bi-
directional buffer and CPU controls LPR so that it can manage multiple telephone lines.
I/O address for LPR access is fixed per each free slot. CPU discriminates the sort of LPR
