Am79213/Am79C203/031 Data Sheet
The Am79213/Am79C203/031 Advanced Subscriber
Line Interface chip set implements a universal telephone
line interface function. This enables the design of a single,
low cost, high performance, fully software programmable
line interface card for multiple country applications world
wide. All AC, DC, and signaling parameters are fully
programmable via the microprocessor interface.
Additionally, the ASLIC device and ASLAC device have
integrated self test and line test capabilities to resolve
faults to the line or line circuit. The integrated test
capability is crucial for remote applications where
dedicated test hardware is not cost effective. The
Technical Reference, PID 21325A is recommended to be
used with this document.
