General Description
The control system of the main unit is composed of the main central processing card (DMPR card) controlling the entire system
and exchanging voice data, the circuit control section (LPR/LC) controlling various telephone lines and the power supply section
(POWER).
DMPR card, LPR/LC and POWER are connected each other through the System BUS (ADDRESS BUS, DATA BUS and CON-
TROL BUS). DMPR card and LPR/LC are under I/O control (I/O Read/Write) by DMPR card.
DMPR card controls LPR which have a microprocessor by the lnter-Microprocessor Communication System supported by
ASIC. Those are, DMPR card and LPR exchange controlling messages through bi-directional buffer and CPU controls LPR so
that it can manage multiple telephone lines. Since LC does not have a microprocessor, it is completely controlled through ASIC
from DMPR card.
I/O address for LPR access is fixed for 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 DMPR card.

DMPR Card
This card is the main control section of main unit. It controls all the cards mounted on the free slots, and communication of RS-
232C ports. DLC port of onboard is controlled.
There are two LED (BATT ALARM, SD ACCESS), one SD card slot, one push switch, one slide switch, one USB port, one RS-
232C connector,two RJ11 connectors(DLC),one RJ45 connector (MOH and EPG) in the front of DMPR card. BATT ALARM LED
light red if the output of the lithium battery in DMPR card is set to about 2.8V or less. During access to SD card, it green-blinks
or SD ACCESS LED light and blink. Enclosed SD card is used for SD card slot on a main part, putting in. The main program is
stored in SD card. It connects with PC and a USB port is used for a maintenance or a system setup. The external sound source
for BGM or suspension sound is connected to a RJ45 connector. A speaker with amplifier is connected to external paging at
RJ45 connector. Light Emitting Diode (RUN indicator, ALARM indicator) arranged at the main part upper part is directly con-
trolled from DMPR card, and shows the state of a system of operation.
This control circuit executes the control signals for the exchange process, and this card is composed of the following
(A) 32bit CPU (32bit data bus)
(B) SDRAMs, SRAMs
(C) Flash memorys
(D) Lithium Battery for back-up of clock IC and Static RAMs
232C ports. DLC port of onboard is controlled.
