line alarm indication signal (AIS) code
The code generated by a regenerator upon loss of input signal or loss of frame. The line AIS signal will maintain operation of the downstream regenerators and therefore prevent generation of unnecessary alarms. At the same time, data and orderwire communication is retained between the regenerators and the downstream line terminating equipment (LTE). [T1.105-1988]
