ANALOG SUBSCRIBER HYBRID CIRCUIT PACK FOR 4 CHANNELS

摘要

PURPOSE: An analog subscriber hybrid circuit pack for 4 channels is provided to receive 4 channels using single pack to easily perform a PCB design by controlling a tip/ring signal transmitted through 4 subscriber line matching units in 4-channel subscriber line voice processing unit. CONSTITUTION: A control unit controls a hybrid(1100) for transmitting data transmitted from 4 channels within the hybrid(1100) through a switch. A relay(1110) of the hybrid(1100) receives a tip/ring signal inputted from a transmitting telephone through a channel to transmit the received tip/ring signal to a receiving telephone and changes the tip/ring signal to a test block when testing a function of the hybrid(1100). A subscriber line matching unit(1120) receives the tip/ring signal transmitted from the transmitting telephone through the relay(1110) and provides a current for performing a communication with the receiving telephone. A 4-channel subscriber line voice processing unit(1130) converts an analog voice data transmitted through the subscriber line matching unit(1120) into a digital voice data, and converts a digital voice data transmitted from the switch into an analog voice data.
