24.4. CIRCUIT OPERATIONS
24.4.1. Option Card (KX-TE82493X)
24.4.1.1. Call ID Detect Circuit
Circuit Operation
This card has three CALL ID detect circuits for support of three COL parts. If necessary to detect CALL ID on eight COLS then
three KX-TE82493 cards are required to be installed in the system. If only required to detect CALL ID on three COLS, then only
one KX-TE82493 card is required.
Incoming signal from COL is detected by CALL ID IC. The CALL ID data changed to serial data from parallel data (8 bit data)
by FPGA. After, the 16 bit CPU detect this 8 bit data and sending the CALL ID data for PITS.
