Analog Telephony Interface Module
Benefits
• Field Programmable
• Operating System Independent
• Bellcore Compliant
• Isolated Analog Telephony Interface
The SocketSLIC
®
interface module is a complete, ready-to-integrate isolated and programmable analog-to-PCM
interface. It allows the user to choose the appropriate telephony interface when the system is configured either
in manufacturing or in the field. This flexibility adds convenience, low cost and quick time to market to designing
modern communication systems or updating existing telephony systems. The SocketSLIC interface module takes
care of the many standard analog interfaces allowing the designer to focus on the digital design.
