System Components
2.1.1 Port Card
The following two types of Port cards can be installed in the KX-TVP200.
• 4 Digital ports expansion card (KX-TVP204)
• 2 Digital/Analog ports expansion card (KX-TVP102)
No Port cards are installed at the factory.
Please purchase above two port cards per your requirement.
KX-TVP102
KX-TVP102 consists of the following two cards:
• Telephone line interface card
• Digital signal processor (DSP) card
The telephone line interface transmits and receives analog and digital signals to
and from the telephone line. The analog input signal is digitized at a sampling
rate of 8kHz to create a 16-bit digital signal.
The DSP has the following features.
• Voice Compression and Decompression
• DTMF Detection
• DTMF Generation
• Call Progress Tone Detection
KX-TVP204
KX-TVP204 consists of a telephone line interface and a DSP.
The telephone interface of the KX-TVP204 transmits and receives only digital sig-
nals to and from the telephone line. The DSP has the same features as the KX-
TVP102.
2.1.2 CPU Card
The CPU card includes the central microprocessor, Flash ROM, dynamic RAM,
system controller, a Rotary switch and a RS-232C interface. It is mounted inside
the main cabinet.
The central microprocessor communicates with and controls the DSPs on the Port
card via FIFO memory.
The Flash memory stores ROM-based system boot program, operating system, pro-
duction-diagnostic software and basic application program.
Parts of the Flash memory (except the fixed boot part) can be updated from the
hard disk if they are out of date.
The other application programs and the system administration table from the hard
disk are read into dynamic RAMs for use by the system.
