Control Interface (GCI). 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.
Reference, document PID 21324A is recommended.
