26.4. EXPLANATION OF BLOCK DIAGRAM
26.4.1. Option Card (KX-TE82483X)
26.4.1.1. CO Interface Circuit
There are the interface circuits linking the CO line (CO4 -CO6) and the cross point circuit section.
26.4.1.2. Cross Point Circuit
This is a space division switching system for connecting the following:
The eight extension circuits with the eight CO,DTMF generator, DTMF receiver, INT-CALL ID,MODEM,OGM, BV, paging, music on
hold, tone etc.
It is composed of 3 C-MOS IC´s. (8 X 16 matrix: 1pce 4 X 8 matrix:1pce, 8 X 8 matrix:1pce)
26.4.1.3. Intercom Circuit
This is the interface circuit of the single line telephone, and it is composed of 8 intercom circuit. (ICM9-16)
26.4.1.4. Power Failure Through Call Switching Circuit
This card has one power failure transfer circuit. (CO4-EXT109)
26.4.1.5. DATA Communication Circuit
The APT i/f module which performs communication with a private telephone machine is built in ASIC located main unit.
26.4.1.6. DTMF Receiver Circuit
The circuit which receives the Dial Tone Multi Frequency by which extension dispatch is carried out with the DTMF receiver
connected to the crossing point.
26.4.1.7. INT CALL ID Circuit
FSK/Dial Tone Multi Frequency generated by DSP in ASIC are connected even to a crossing point through AMP.
The circuit which sends out a CALLID signal to the telephone connected to an extension by connecting the line of INT-CALL-ID with
arbitrary extensions.
