Outline
4.5.1.
General Description
The control system of this unit is composed of the main control section (IPCMPR) controlling the entire system, exchanging
voice data, the circuit control section (LPR) controlling various telephone lines and the power supply section (POWER).
IPCMPR, LPR and POWER are connected each other through the System BUS (ADDRESS BUS, DATA BUS and CONTROL
BUS). IPCMPR 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, IPCMPR 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 through the inter-processor communi-
cation system.
POWER detects the voltage drop of the AC input and the DC output and transfers it to IPCMPR.
4.5.2.
IPCMPR Card
This card is the main control section of this unit. It controls all the cards mounted on the free slots, and communication of RS-
232C ports.
The front of the IPCMPR card is equipped with two LEDs (LED1 and LED2) that indicate the operating status of this card, There
are no rotary switches on IPCMPR and a push switch used to execute the system reset.
This control circuit execute the control signals for the exchange process, and this card is composed of the following
(A) 32bit CPU (32bit data bus)
(B) DDR_SDRAMs, SRAM
(C) Flash memory
(D) Lithium Battery for back-up of clock IC and Static RAM
4.5.3.
Back Board
BB (back board) is the mother board of the basic shelf. This board connects each card (POWER, IPCMPR, and optional cards)
together. This board has RS-232C connector, FAN connector and LED connector.
4.5.4.
Power Supply Unit
This unit is switching regulator power supply and supplies DC voltages to IPCMPR card, optional card (free slot).
