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.
