SLICs

SLICs (Subscriber Line Interface Cards) are modular electronic circuits that interface with a telecommunications network. They are used to convert analog voice communications to digital and vice-versa. SLIC supplies the interface between the analog loop of the telecommunication network and a digital central office. The environments that benefit from SLIC cards are digital central office to customer-premises connections, private branch exchanges (PBX), remote terminals (RT) and digital loop carrier (DLC) systems.
