Block Name : MOH, External Pager interface Circuit
Circuit Configuration :

• CODEC : IC700

EPG port is used for external paging function, MOH port is also used for external MOH sound input interface. This MOH inter-
face has AGC function to avoid large input level signal.

Block Name : DSP, Door phone, FAN, RS232C, Power Connector Circuit
Description :

DSP1,2 and Door phone card are connected to expansion bus interface. And also these option card are powered from these
interface connectors.
FAN interface is used for FAN driving power supply, also FAN alarm signal is monitored via this connector.
Power connector is used for DC+15V power input interface. And DC/AC-Alarm signal is used to monitor Power Unit alarm sta-
tus.

Block Name : FAX and optional service card (free slot) Storage Memory interface Circuit
Description :

FAX and Option card (free slot) are connected to expansion bus interface. Option card power supply function is also con-
tained.
Storage Memory Card  slot is connected to expansion bus interface too. CPU will access Storage Memory Card  Memory via
expansion bus interface.

Block Name : Internal Power Supply Circuit and Reset Signal Generate
Circuit Configuration :

• DC-DC Converter (DC+15 to 3.3V/5.0V) : IC1200
• DC-DC Converter (DC+15 to 5.0V for USB) : IC1210
• DC-DC Converter (DC+5.0V to 1.8V) : IC1201
• DC-DC Converter (DC+5.0V to 0.98V) : IC1202
• Regulator (DC+3.3V to 2.5V) : IC1203
• Regulator (DC+3.3V to 1.2V) : IC1205
• Regulator (DC+1.8V to 0.9V) : IC103

Every voltage used in Motherboard is generated from DC+15V Input.

And also each output voltage monitored by voltage detection IC and reset signal is generated by these IC.

KX-NS1000 provides various Line Interface functions. The line interface functions; such as SLT, COLine, and Digital Trunk are
mounted on each Option Service Card, and these functions are controlled directly from CPU on the Mother Board. 
In the line interface function part, voice signal is converted into PCM data format and transferred to the Mother Board via Voice
Bus on the Back Board. PBX function is achieved because the PCM data is exchanged by the Local Time Switch on the FPGA . 
On the other hand, it is possible to mount the DSP card on the Mother Board. DSP card converts the PCM voice signal into the
VoIP packet and also provides CODEC conversion function. 
KX-NS1000 can also be used as the fax server, with the installation of a fax card. The fax card terminates the arriving fax data
from an outside line,  and convert it to a fax image data. 
The power unit supplies Power to the Mother Board, and also to the Option Service Card by way of Back Board.

Mother Board is a control part of this system, and controls all the functions of each Option Card on this device. 
For more detailed information on the Mother Board part; please refer to Chapter 4.3 "Mother Board Circuit Operation".

The Back Board functions as a backplane to connect Mother Board with Option Service Card. Only passive parts such as con-
nectors are mounted on the Back Board. The pattern of Option Service Card is relayed to the Mother Board by electric signal.

This unit is switching regulator power supply and supplies DC voltages to Mother Board, Option Service Card (free slot).
